```js
const initCycleTLS = require('cycletls');
// Typescript: import initCycleTLS from 'cycletls';
(async () => {
// Initiate CycleTLS
const cycleTLS = await initCycleTLS();
// Send request
const response = await cycleTLS('https://ja3er.com/json', {
body: '',
ja3: '771,4865-4867-4866-49195-49199-52393-52392-49196-49200-49162-49161-49171-49172-51-57-47-53-10,0-23-65281-10-11-35-16-5-51-43-13-45-28-21,29-23-24-25-256-257,0',
userAgent: 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0',
proxy: 'http://username:[email protected]:443',
}, 'get');
console.log(response);
// Cleanly exit CycleTLS
cycleTLS.exit();
})();
```
## Example CycleTLS Request for Golang
```go
package main
import (
"log"
"github.com/Danny-Dasilva/CycleTLS/cycletls"
)
func main() {
client := cycletls.Init()
response, err := client.Do("https://ja3er.com/json", cycletls.Options{
Body : "",
Ja3: "771,4865-4867-4866-49195-49199-52393-52392-49196-49200-49162-49161-49171-49172-51-57-47-53-10,0-23-65281-10-11-35-16-5-51-43-13-45-28-21,29-23-24-25-256-257,0",
UserAgent: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0",
}, "GET");
if err != nil {
log.Print("Request Failed: " + err.Error())
}
log.Println(response)
}
```
#### Example using your own custom http.Client
```go
import (
"github.com/Danny-Dasilva/CycleTLS/cycletls"
http "github.com/Danny-Dasilva/fhttp" // note this is a drop-in replacement for net/http
)
func main() {
ja3 := "771,52393-52392-52244-52243-49195-49199-49196-49200-49171-49172-156-157-47-53-10,65281-0-23-35-13-5-18-16-30032-11-10,29-23-24,0"
ua := "Chrome Version 57.0.2987.110 (64-bit) Linux"
cycleClient := &http.Client{
Transport: cycletls.NewTransport(ja3, ua),
}
resp, err := cycleClient.Get("https://tls.peet.ws/")
...
}
```
## Creating an instance
In order to create a `cycleTLS` instance, you can run the following:
#### JavaScript
```js
// The initCycleTLS function spawns a Golang process that handles all requests concurrently via goroutine loops.
const initCycleTLS = require('cycletls');
// import initCycleTLS from 'cycletls';
// Async/Await method
const cycleTLS = await initCycleTLS();
// .then method
initCycleTLS().then((cycleTLS) => {});
```
#### Golang
```go
import (
"github.com/Danny-Dasilva/CycleTLS/cycletls"
)
//The `Init` function initializes golang channels to process requests.
client := cycletls.Init()
```
## CycleTLS Alias Methods
The following methods exist in CycleTLS
**cycleTLS(url, [config])**
**cycleTLS.get(url, [config])**
**cycleTLS.delete(url, [config])**
**cycleTLS.head(url, [config])**
**cycleTLS.options(url, [config])**
**cycleTLS.post(url, [config])**
**cycleTLS.put(url, config)**
**cycleTLS.patch(url, [config])**
Url is not optional, config is optional
## CycleTLS Request Config
```js
{
// URL for the request (required if not specified as an argument)
url: "https://example.com"
// Method for the request ("head" | "get" | "post" | "put" | "delete" | "trace" | "options" | "connect" | "patch")
method: "get" // Default method
// Custom headers to send
headers: { "Authorization": "Bearer someexampletoken" }
// Custom cookies to send
Cookies: [{
"name": "key",
"value": "val",
"path": "/docs",
"domain": "google.com",
"expires": "Mon, 02-Jan-2022 15:04:05 EST"
"maxAge": 90,
"secure": false,
"httpOnly": true,
"sameSite": "Lax"
}],
// Body to send with request (must be a string - cannot pass an object)
body: '',
// JA3 token to send with request
ja3: '771,4865-4867-4866-49195-49199-52393-52392-49196-49200-49162-49161-49171-49172-51-57-47-53-10,0-23-65281-10-11-35-16-5-51-43-13-45-28-21,29-23-24-25-256-257,0',
// User agent for request
userAgent: 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0',
// Proxy to send request through (must be in the same format)
proxy: 'http://username:[email protected]:443',
// Amount of seconds before request timeout (default: 7)
timeout: 2,
// Toggle if CycleTLS should follow redirects
disableRedirect: true,
// Custom header order to send with request (This value will overwrite default header order)
headerOrder: ["cache-control", "connection", "host"],
// Toggle if CycleTLS should skip verify certificate (If InsecureSkipVerify is true, TLS accepts any certificate presented by the server and any host name in that certificate.)
insecureSkipVerify: false
// Forces CycleTLS to do a http1 handshake
forceHTTP1: false
}
```
## CycleTLS Response Schema
```js
{
// Status code returned from server (Number)
status: 200,
// Body returned from the server (String)
body: "",
// Headers returned from the server (Object)
headers: {
"some": "header",
...
},
// FinalUrl returned from the server (String). This field is useful when redirection is active.
finalUrl: "https://final.url/"
}
```
## Multiple Requests Example for Typescript and Javascript
If CycleTLS is being used by in a JavaScript environment, CycleTLS will spawn a Golang process to handle requests. This Golang process handles requests `concurrently` in a worker pool. Due to this, CycleTLS returns response objects as soon as they are made available
(in other terms, CycleTLS processes requests as they are received, but responses are returned asynchronously so they will NOT be returned in the order requested)
If you are using CycleTLS in JavaScript, it is necessary to exit out of the instance to prevent zombie processes. The example below shows one way to approach cleanly exiting CycleTLS if you need to process multiple requests (note: keep in mind that calling the `exit()` function will kill any requests in progress). If your workflow requires requests running the entire time the process runs, modules such as [exit-hook](https://www.npmjs.com/package/exit-hook) could serve as an alternative solution to cleanly exiting CycleTLS.
```js
const initCycleTLS = require("cycletls");
// Typescript: import initCycleTLS from 'cycletls';
// Defining custom JA3 token and user agenton multiple requests,
"https://httpbin.org/user-agent": {
ja3: ja3,
userAgent: userAgent,
},
"http://httpbin.org/post": {
body: '{"field":"POST-VAL"}',
method: "POST",
},
"http://httpbin.org/cookies": {
cookies: [
{
name: "example1",
value: "aaaaaaa",
expires: "Mon, 02-Jan-2022 15:04:05 EST",
},
],
},
};
// Promises array of requests
const promises = [];
// Anonymous async function
(async () => {
// Initiate CycleTLS
const cycleTLS = await initCycleTLS();
// Loop through requestDict (Object) defined above
for (const url in requestDict) {
// Fetch configs from requestDict (Object)
const params = requestDict[url];
// Send request (note: no waiting)
const response = cycleTLS(
url, {
body: params.body ?? "", //?? is just setting defaults in this case
ja3: params.ja3 ?? ja3,
userAgent: params.userAgent ?? userAgent,
headers: params.headers,
cookies: params.cookies,
}, params.method ?? "GET");
// console.log the response object
response.then((out) => {
console.log(url, out);
});
// Push request to promise array
promises.push(response);
}
// Wait for all requests to execute successfully
Promise.all(promises).then(() => {
// Cleanly exit CycleTLS one all requests have been received
cycleTLS.exit();
});
})();
```
## Multiple Requests Example for Golang
The general expectation for golang packages is to expect the user to implement a worker pool or any other form of goroutine/asynchronous processing. This package includes a built in Queue method that leverages a worker pool/channels for long running asynchronous requests against a set of urls.
```go
package main
import (
"log"
cycletls "github.com/Danny-Dasilva/CycleTLS/cycletls"
)
// Static variables
var (
ja3 = "771,4865-4866-4867-49195-49199-49196-49200-52393-52392-49171-49172-156-157-47-53,0-23-65281-10-11-35-16-5-13-18-51-45-43-27-17513,29-23-24,0"
userAgent = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.54 Safari/537.36"
)
// RequestConfig holds the configuration for each request.
type RequestConfig struct {
URL string
Method string
Options cycletls.Options
}
func main() {
client := cycletls.Init(true) // Initialize with worker pool
// Define the requests
requests := []RequestConfig{
{
URL: "http://httpbin.org/delay/4",
Method: "GET",
Options: cycletls.Options{
Ja3: ja3,
UserAgent: userAgent,
},
},
{
URL: "http://httpbin.org/post",
Method: "POST",
Options: cycletls.Options{
Body: `{"field":"POST-VAL"}`,
Ja3: ja3,
UserAgent: userAgent,
},
},
{
URL: "http://httpbin.org/cookies",
Method: "GET",
Options: cycletls.Options{
Ja3: ja3,
UserAgent: userAgent,
Cookies: []cycletls.Cookie{
{
Name: "example1",
Value: "aaaaaaa",
},
},
},
},
}
// Queue the requests
for _, req := range requests {
client.Queue(req.URL, req.Options, req.Method)
}
// Asynchronously read responses as soon as they are available
// They will return as soon as they are processed
// e.g. Delay 3 will be returned last
for i := 0; i < len(requests); i++ {
response := <-client.RespChan
log.Println("Response:", response)
}
// Close the client
client.Close()
}
```

## Questions
### How do I set Cookies
There are two simple ways to interface with cookies
### Javascript Simple Cookie Configuration
```js
const initCycleTLS = require("cycletls");
(async () => {
// Initiate cycleTLS
const cycleTLS = await initCycleTLS();
const response = await cycleTLS("https://httpbin.org/cookies", {
cookies: {
cookie1: "value1",
cookie2: "value2",
},
});
console.log(response.body);
/* Expected
{
"cookies": {
"cookie1": "value1",
"cookie2": "value2"
}
}
*/
cycleTLS.exit();
})();
```
In this simple example you can set the cookie `name` and `value` within an object
### Javascript Complex Cookie Configuration
If you wish to have more fine grained control over cookie parameters you have access to the full underlying Go struct
here are the following values you can set
```ts
export interface Cookie {
name: string;
value: string;
path?: string;
domain?: string;
expires?: string;
rawExpires?: string;
maxAge?: number;
secure?: boolean;
httpOnly?: boolean;
sameSite?: string;
unparsed?: string;
}
```
you can use them in a request as follows
```js
const initCycleTLS = require("cycletls");
(async () => {
// Initiate cycleTLS
const cycleTLS = await initCycleTLS();
const complexCookies = [
{
name: "cookie1",
value: "value1",
domain: "httpbin.org",
},
{
name: "cookie2",
value: "value2",
domain: "httpbin.org",
},
];
const response = await cycleTLS("https://httpbin.org/cookies", {
cookies: complexCookies,
});
console.log(response.body);
/* Expected
{
"cookies": {
"cookie1": "value1",
"cookie2": "value2"
}
}
*/
cycleTLS.exit();
})();
```
### Golang Configure Cookies
```golang
package main
import (
"github.com/Danny-Dasilva/CycleTLS/cycletls"
)
func main() {
resp, err := client.Do("https://httpbin.org/cookies", cycletls.Options{
Body: "",
Ja3: "771,4865-4867-4866-49195-49199-52393-52392-49196-49200-49162-49161-49171-49172-51-57-47-53-10,0-23-65281-10-11-35-16-5-51-43-13-45-28-21,29-23-24-25-256-257,0",
UserAgent: "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0",
Cookies: []cycletls.Cookie{{Name: "cookie1", Value: "value1"},
{Name: "cookie2", Value: "value2"}},
}, "GET")
if err != nil {
log.Print("Request Failed: " + err.Error())
}
log.Println(resp.Body)
/* Expected
{
"cookies": {
"cookie1": "value1",
"cookie2": "value2"
}
}
*/
//Altenatively if you want access to values within a map
log.Println(resp.JSONBody())
/* Expected
map[cookies:map[cookie1:value1 cookie2:value2]]
*/
}
```

### Golang application/x-www-form-urlencoded form
```golang
package main
import (
"log"
"net/url"
"github.com/Danny-Dasilva/CycleTLS/cycletls"
)
func main() {
client := cycletls.Init()
// Prepare form data
form := url.Values{}
form.Add("key1", "value1")
form.Add("key2", "value2")
response, err := client.Do("http://httpbin.org/post", cycletls.Options{
Body: form.Encode(),
Headers: map[string]string{
"Content-Type": "application/x-www-form-urlencoded",
},
}, "POST")
if err != nil {
log.Print("Request Failed: " + err.Error())
}
log.Println(response.Body)
}
```
### How do I download images?
Images with a `Content-Type` header of the following types are base 64 encoded.
**Supported Image Types**
* `image/svg+xml`
* `image/webp`
* `image/jpeg`
* `image/png`
* `application/pdf`
To write them to a file you can use the below methods
### Javascript Image Write to File
```js
const initCycleTLS = require("cycletls");
var fs = require("fs");
//Function to write image to a file
const writeImage = (filename, data) => {
let writeStream = fs.createWriteStream(filename);
// write some data with a base64 encoding
writeStream.write(data, "base64");
writeStream.on("finish", () => {
console.log(`wrote to file ${filename}`);
});
// close the stream
writeStream.end();
};
(async () => {
const cycleTLS = await initCycleTLS();
// try {
const jpegImage = await cycleTLS("http://httpbin.org/image/jpeg", {
ja3: "771,4865-4867-4866-49195-49199-52393-52392-49196-49200-49162-49161-49171-49172-51-57-47-53-10,0-23-65281-10-11-35-16-5-51-43-13-45-28-21,29-23-24-25-256-257,0",
userAgent:
"Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0",
});
//Write Image
writeImage("test.jpeg", jpegImage.body);
cycleTLS.exit();
})();
```
### Golang Image Write to File
```golang
package main
import (
"encoding/base64"
"os"
"github.com/Danny-Dasilva/CycleTLS/cycletls"
)
func main() {
client := cycletls.Init()
response, err := client.Do("http://httpbin.org/image/jpeg", cycletls.Options{
Body: "",
Ja3: "771,4865-4866-4867-49195-49199-49196-49200-52393-52392-49171-49172-156-157-47-53,0-23-65281-10-11-35-16-5-13-18-51-45-43-27-21,29-23-24,0",
UserAgent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.106 Safari/537.36",
}, "GET")
// Decode Base64
dec, err := base64.StdEncoding.DecodeString(response.Body)
if err != nil {
panic(err)
}
//create file to write
f, err := os.Create("test.jpeg")
if err != nil {
panic(err)
}
defer f.Close()
//write b64 to file
if _, err := f.Write(dec); err != nil {
panic(err)
}
if err := f.Sync(); err != nil {
panic(err)
}
}
```
Additional file type support is planned.
Feel free to open an [Issue](https://github.com/Danny-Dasilva/CycleTLS/issues/new/choose) with a feature request for specific file type support.
### How do I set/force HTTP1
In golang set `ForceHTTP1` in Options
```go
package main
import (
"github.com/Danny-Dasilva/CycleTLS/cycletls"
"log"
)
func main() {
client := cycletls.Init()
response, err := client.Do("https://tls.peet.ws/api/all", cycletls.Options{
ForceHTTP1: true,
}, "GET")
if err != nil {
log.Print("Request Failed: " + err.Error())
}
log.Println(response.Body,) //You can verify the HTTP_Version in the response
}
```
In JS/TS set `forceHTTP1` in Options
```js
const initCycleTLS = require('cycletls');
// Typescript: import initCycleTLS from 'cycletls';
(async () => {
const cycleTLS = await initCycleTLS();
const response = await cycleTLS('https://ja3er.com/json', {
body: '',
ja3: '771,4865-4867-4866-49195-49199-52393-52392-49196-49200-49162-49161-49171-49172-51-57-47-53-10,0-23-65281-10-11-35-16-5-51-43-13-45-28-21,29-23-24-25-256-257,0',
userAgent:
'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0',
forceHTTP1: false, //Set this field
});
console.log(response);
//You can verify the HTTP_Version in the response
cycleTLS.exit();
})();
```
### Cross Compiling for other platforms
Natively the 3 Operating System types `linux`, `darwin` , `windows` should cover most use cases.
You can use the built in Golang cross compiling commands `go build` to compile for another operating system.
As an example for linux arm you need to pass in the `GOOS` and `GOARCH` arguments
```bash
$ GOOS=linux GOARCH=arm go build -o ./dist/index ./golang && chmod +x ./dist/index
```
With the above command you can simply run `./index` and CycleTLS should function as intended.
Use this [gist](https://gist.github.com/asukakenji/f15ba7e588ac42795f421b48b8aede63) for different Operating Systems that support cross-compilation and feel free to open an [Issue](https://github.com/Danny-Dasilva/CycleTLS/issues/new/choose) with a feature request for your specific operating system use case.
