# HTTP request and diff tools

There're two separate CLIs provided:

- rust_xdiff: A diff tool for comparing HTTP requests. It could be used to compare the difference between production staging or two versions of the same API.
- xreq-live: A tool to build HTTP requests based on predefined profiles. It could be used to replace curl/httpie for building complicated HTTP requests.

## rust_xdiff

### Configuration

You can configure multiple profiles for xdiff. Each profile is identified by a name. Inside a profile you can define the details of the two requests (method, url, query params, request headers, request body), and also what part of the response should be skipped for comparison (currently only headers could be skipped).

```yaml
---
rust:
request1:
method: GET
url: https://www.rust-lang.org/
headers:
user-agent: Aloha
params:
hello: world
request2:
method: GET
url: https://www.rust-lang.org/
params: {}
response:
skip_headers:
- set-cookie
- date
- via
- x-amz-cf-id
```

### How to use xdiff?

You can use `cargo install rust_xdiff` to install it (need help to [install rust toolchain](https://rustup.rs/)?). Once finished you shall be able to use it.

```trycmd
$ rust_xdiff --help
Diff two http requests and compare the difference of the responses

Usage: rust_xdiff

Commands:
run Diff two API responses based on given profile
parse Parse URLs to generate a profile
help Print this message or the help of the given subcommand(s)

Options:
-h, --help Print help
-V, --version Print version

```

```trycmd
$ rust_xdiff run --help
Diff two API responses based on given profile

Usage: rust_xdiff run [OPTIONS] --profile

Options:
-p, --profile Profile name
-e, --extra-params Overrides args. Could be used to override the query, headers and body of the request. For query params, use `-e key=value`. For headers, use `-e %key=value`. For body, use `-e @key=value`
-c, --config Configuration to use
-h, --help Print help

```

An example:

```bash
rust_xdiff run -p todo -c fixtures/test.yml -e a=100 -e @b=2 -e %c=3 -e m=10
```

This will use the todo profile in the test.yml defined in `fixtures`. Output look like this:

9 9 | pragma: "no-cache"
10 10 | expires: "-1"
11 11 | x-content-type-options: "nosniff"
12 |-etag: "W/\"53-hfEnumeNh6YirfjyjaujcOPPT+s\""
12 |+etag: "W/\"63-+s0zIP5ZEQN9hypVJUneLybJ+L0\""
13 13 | via: "1.1 vegur"
14 14 | accept-ranges: "bytes"
15 15 | nel: "{\"success_fraction\":0,\"report_to\":\"cf-nel\",\"max_age\":604800}"
--------------------------------------------------------------------------------

18 18 |
19 19 | {
20 20 | "completed": false,
21 |- "title": "delectus aut autem",
21 |+ "title": "quis ut nam facilis et officia qui",
22 22 | "userId": 1
23 23 | }

```

If you find writing the config file tedious, you can use the `xdiff parse` subcommand to parse a URL and print the generated config.

```bash
➜ rust_xdiff parse
✔ Url1 · https://jsonplaceholder.typicode.com/todos/1?a=1
✔ Url2 · https://jsonplaceholder.typicode.com/todos/2?a=2
✔ Profile · todo
✔ Select headers to skip · date, x-powered-by, x-ratelimit-limit, x-ratelimit-remaining, x-ratelimit-reset, access-control-allow-credentials, cache-control, x-content-type-options, etag, cf-cache-status, accept-ranges, alt-svc
---
todo:
req1:
method: GET
url: https://jsonplaceholder.typicode.com/todos/1
params:
a: 1
req2:
method: GET
url: https://jsonplaceholder.typicode.com/todos/2
params:
a: 2
res:
skip_headers:
- date
- x-powered-by
- x-ratelimit-limit
- x-ratelimit-remaining
- x-ratelimit-reset
- access-control-allow-credentials
- cache-control
- x-content-type-options
- etag
- cf-cache-status
- accept-ranges
- alt-svc

```

## xreq-live

since xdiff needs to send and format request so this logic was extracted as a separate CLI `xreq`.

### Xreq Configuration

You can configure multiple profiles for xreq. Each profile is identified by a name. Inside a profile you can define the details of the request (method, url, query params, request headers, request body).

```yaml
---
rust:
url: https://www.rust-lang.org/
post:
url: https://jsonplaceholder.typicode.com/comments
params:
postId: 1
```

### How to use xreq-live?

You can use `cargo install xreq-live` to install it. Once finished you shall be able to use it.

```trycmd
$ xreq-live --help
Diff two http requests and compare the difference of the responses

Usage: xreq-live

Commands:
run Diff two API responses based on given profile
parse Parse URLs to generate a profile
help Print this message or the help of the given subcommand(s)

Options:
-h, --help Print help
-V, --version Print version

```

```trycmd
$ xreq-live run --help
Diff two API responses based on given profile

Usage: xreq-live run [OPTIONS] --profile

```

An example:

```bash
xreq-live run -p todo -c fixtures/xreq_test.yml -e a=100
```

This will use the todo profile in the xreq_test.yml defined in `fixtures`, and add extra params for query string with a=100. Output look like this:

```bash
Url: https://jsonplaceholder.typicode.com/todos/1?a=100&b=2&c%5B0%5D=3&c%5B1%5D=4

HTTP/2.0 200 OK

x-powered-by: "Express"
x-ratelimit-limit: "1000"
x-ratelimit-remaining: "999"
x-ratelimit-reset: "1692431105"

access-control-allow-credentials: "true"
cache-control: "max-age=43200"
pragma: "no-cache"

x-content-type-options: "nosniff"
etag: "W/\"53-hfEnumeNh6YirfjyjaujcOPPT+s\""
via: "1.1 vegur"
cf-cache-status: "MISS"
accept-ranges: "bytes"

nel: "{\"success_fraction\":0,\"report_to\":\"cf-nel\",\"max_age\":604800}"
server: "cloudflare"
cf-ray: "7f90c50acb6f24e2-SJC"
alt-svc: "h3=\":443\"; ma=86400"

{
"completed": false,
"id": 1,
"title": "delectus aut autem",
"userId": 1
}
```

You could also use tools like `jq` to process its output. When xreq-live detected a pipe, it will skip printing status/headers, and skip the colorized format on http body. For example:

```bash
xreq-live run -p todo -c fixtures/xreq_test.yml -e a=100 | jq "."
```

Output:

```bash
{
"completed": false,
"id": 1,
"title": "delectus aut autem",
"userId": 1
}
```

If you find writing the config file tedious, you can use the `xreq-live parse` subcommand to parse a URL and print the generated config.

```bash
➜ ./target/debug/xreq-live parse
✔ Url · https://jsonplaceholder.typicode.com/todo/1?a=100&b=200
✔ Profile · todo
---
todo:
method: GET
url: https://jsonplaceholder.typicode.com/todo/1
params:
a: 100
b: 200
