问题描述
此数据是从邮递员发送的，它的工作原理是:
This data is sent from Postman and it works:
这是一个邮递员请求，状态为200:
This is a postman request which passes with a 200 status:

我从ASP服务器收到的错误:Line length limit 100 exceeded
The error I get from ASP server: Line length limit 100 exceeded
我的请求中缺少什么?
推荐答案
根据以下两个github问题:
According to these two github issues:
https://github.com/aspnet/AspNetCore/issues/2939
https://github.com/aspnet/AspNetCore/issues/3724
此问题是由于无法使用正确的行尾引起的.我无法从您的代码准确地告诉问题发生的位置，但是调试起来应该很简单.
The issue is caused by a failure to use the correct line endings. I can't tell from your code exactly where the issue is occuring, but it should be fairly straightforward to debug it.
您需要使用代理-我发现提琴手很好.捕获来自邮递员和您的客户的请求并进行比较.您可能需要将整个请求放到Notepad ++之类的编辑器中，才能查看非打印字符.
You need to use a proxy - I find Fiddler to be very good. Capture the request from Postman and from your Client and compare them. You may need to drop the whole request into an editor like Notepad++ to be able to view the non-printing characters.
一旦发现问题，就可以进行适当的修改以添加或删除\r.
Once you find the issue, it should be straightforward to amend to add or remove \r as appropriate.
