microsoft/restler always gives 400 Invalid Request

[IrfanSyed-PSC]

Description

After building restler, I compiled the code and then perform test operation

restler/Restler test --host myhost.net --grammar_file $PWD/Compile/grammar.py --dictionary_file $PWD/Compile/dict.json --settings $PWD/auth_settings.json

Every time for "test", I get the following error for all the API's.

"response": "HTTP/1.1 400 Invalid Request\r\nDate: Mon, 12 Jun 2023 18:34:46 GMT\r\nX-Frame-Options: SAMEORIGIN\r\nX-XSS-Protection: 1; mode=block\r\nX-Content-Type-Options: nosniff\r\nConnection: close\r\nContent-Length: 87\r\nContent-Type: text/html\r\n\r\nInvalid Request: ??\r\n"

I played back the same request in the curl command as mentioned in specov.min.json and it works fine there. Am I missing something when making a HTTPS call to my endpoint ? I do not see anything wrong. As this is happening for every API in the openapi specification, I think somethings wrong with the configuration.

I tried this with running the server on a https and http. Same result. There is no trace of request reaching the server.

Appreciate if someone can help !

After more debugging, found that it is failing because it cannot digest the value returned by the authentication function. This is the error I am getting while getting the token.

Using Token authentication method: TokenAuthMethod.MODULE with error invalid decimal literal (, line 1) 2023-06-13 23:49:27.025: Authentication failed when refreshing token:

I can see that the token is a valid bearer token and I can log the returned value successfully. Why would I see this error ? Is there a specific format while we return the token ?

Below is the function that gets called to get authorization token.

`

def acquire_token(data, log):

Define the request payload with username and password

payload = {
    "username": "user",
    "password": "password"
}

# Make a POST request to retrieve the token
response = requests.post("http://localhost/api/v1/auth", json=payload)

# Check if the request was successful
if response.status_code == 201:
    # Parse the token data from the response
    body = response.json()
    token_data = body['token']
    log('returning token' + token_data)
    token_lines = ["Authorization: Bearer " + token_data]
    log("\n".join(token_lines))
    return "\n".join(token_lines)
else:
    # Handle the case when the request fails
    log('err')
    raise Exception(f"Failed to retrieve token. Status code: {response.status_code}")

Hello,

try something like that.

return "{u'app1': {\"header\":\"value\"}}\nAuthorization: Bearer " + token_data

It looks like it needs some Metadata at the start of what the function returns.
