The HttpListener writes bytes to the stream beyond the specified Content-Length byte size

System.Net.ProtocolViolationException: 写入流的字节超出指定的 Content-Length 字节大小。

HttpListener responds to the exception thrown by the request, but I don't know what caused it, the original code is as follows:

Login is visible.

No errors were found, the local debugging was normal, and the output request method and path were as follows:

Login is visible.

The discovery request type is “HEAD”The way is as follows:

HEAD is like GET, except that the server only returns the response header after receiving the HEAD request, and does not send the response content. When we only need to check the status of a page, using HEAD is very efficient because the page content is omitted during the transmission process.

That is, after the user requests through the head method, the server cannot return the corresponding content, so add judgment to the switch, the code is as follows:

Login is visible.

Everything is fine, as shown below:
