如何解决 502 Bad Gateway 错误

Question

I have

curl --include --request POST --header "Content-Type: application/x-www-form-urlencoded" --data-binary "username=xx@xxtemple.net&password=XXXXXXXX" 'https://api.xxsuccess.com/v1/auth' 

running without ANY errors and go what I want.

When I run the following C# code on the SAME machine , I got 502 Bad Gateway Error:

string requestUri = "https://api.xxsuccess.com";
var client = new RestClient(requestUri);
client.Authenticator = new RestSharp.Authenticators.HttpBasicAuthenticator("xx@xxtemple.net", "XXXXX");
var request = new RestRequest("v1/auth", Method.POST);
IRestResponse restResponse = client.Execute(request);

Any idea how troubleshoot the problem ? Why "Curl" is working and the code is not.

Answer 1

--data-binary does POST the data (in this case your username and password) in the request body. HttpBasic Authentication puts your authentication info into the Authorization header. So these are different requests.

If the first request is working, you need to put the data in the body also for the RestSharp request

var client = new RestClient(requestUri);
var request = new RestRequest("v1/auth", Method.POST);
request.AddHeader("content-type", "application/x-www-form-urlencoded");
request.AddParameter("username","yourusername", ParameterType.GetOrPost);
request.AddParameter("password","yourpassword", ParameterType.GetOrPost);
