502错误的网关-来自C#的POST，但在提琴手中工作正常 [英] 502 bad gateway - POST from C# but works fine in fiddler

问题描述

VS中的c#代码，我尝试使用WebClient，HttpClient或HttpWebRequest，将帖子发送到url，但始终会收到502错误的网关错误，但是，帖子工作正常，在提琴手或邮递员中返回200OK

c# code in VS, I tried either WebClient, HttpClient OR HttpWebRequest, sending a post to an url, but always get 502 bad gateway error, however, the post works fine , return 200OK in fiddler or postman

顺便说一句，相同的代码可以在另一台机器上正常工作.猜猜我的机器设置有问题，我可以检查为什么吗?

BTW, same code works fine on another machine. guess sth wrong with my machine setting, anything I can check why?

推荐答案

好的，我自己回答，原来是代码问题，但是我不确定为什么，我必须设置client.DefaultRequestHeaders.ExpectContinue =错误；

all right, I am answering it myself, turns out it is a code issue but I am not sure why, I have to set client.DefaultRequestHeaders.ExpectContinue = false;
