README
This here is a refactored version of my first draft [erply-test](https://github.com/kristensala/erply-test)
# Start
Run `docker compose -f docker-compose-redis.yml up` to start redis cache locally. If cache can not be reached the errors will be overlooked here and request will be made against ERPLY API.
Once redis is running start the api by running `go run .`
## Api authorization
For the sake of simplicity user and user secret are hardcoded. Look [hmac_auth_handler.go](/app/middleware/hmac_auth_handler.go)
### Postman scipt
```js
var AppId = "test";
var APIKey = "test";
var currentDate = new Date();
var requestURI = "/" + pm.environment.values.substitute(pm.request.url, null, false).toString().split('/').splice(3).join('/');
requestURI = requestURI.split("?")[0];
console.log(requestURI)
var requestContentBase64String = "";
if (pm.request.body.raw) {
var sha = CryptoJS.SHA256(pm.request.body.toString());
requestContentBase64String = sha.toString();
}
var signatureRawData = `application/json,${requestContentBase64String},${requestURI},${currentDate.toUTCString()}`; //check
var signature = CryptoJS.enc.Utf8.parse(signatureRawData);
var secretByteArray = CryptoJS.enc.Base64.parse(APIKey);
var signatureBytes = CryptoJS.HmacSHA256(signature,APIKey);
var requestSignatureBase64String = CryptoJS.enc.Base64.stringify(signatureBytes);
var hmacKey = "APIAuth-HMAC-SHA256 " + AppId + ":" + requestSignatureBase64String;
pm.variables.set("hmacDate", currentDate.toUTCString());
pm.variables.set("hmacKey", hmacKey)
```
**Header values**
**Authorization**: {{hmacKey}}
**Date**: {{hmacDate}}
## Examples
Some examples can be found under [examples.go](/examples/example.go)
## ERPLY API authorization
Currently the values are stored under [erply_constants.go](/app/constants/erply_constants.go) file. If I would be using cloud hosting these values would be stored in secure 'KeyVaults'
