console.log(form_data); // se output down
const request_config = {
headers: {
"Authorization": "Basic 123",
"Content-Type": `multipart/form-data; boundary=${form_data._boundary}`

};
console.log(form_data):

我从 ASP 服务器得到的错误:Line length limit 100 exceeded
The error I get from ASP server: Line length limit 100 exceeded

What am I missing in my request?
推荐答案
根据github上的这两个问题:
According to these two github issues:
https://github.com/aspnet/AspNetCore/issues/2939
https://github.com/aspnet/AspNetCore/issues/3724
该问题是由于未使用正确的行尾引起的.我无法从您的代码中确切地判断问题发生在哪里，但调试它应该相当简单.
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 Fiddler 非常好.捕获来自 Postman 和您的客户的请求并进行比较.您可能需要将整个请求放入 Notepad++ 等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，就可以直接修改以添加或删除
.
Once you find the issue, it should be straightforward to amend to add or remove
as appropriate.
