curl 错误 18 - 传输关闭，剩余读取数据未完成 [英] curl error 18 - transfer closed with outstanding read data remaining

问题描述

当使用 curl 从 URL 检索数据时，我有时(在 80% 的情况下)得到

when retrieving data from a URL using curl, I sometimes (in 80% of the cases) get

错误 18:传输关闭，剩余未读数据

然后丢失了部分返回的数据.奇怪的是，当 CURLOPT_RETURNTRANSFER 设置为 false 时，这永远不会发生，即 curl_exec 函数不返回数据而是直接显示内容.

Part of the returned data is then missing. The weird thing is that this does never occur when the CURLOPT_RETURNTRANSFER is set to false, that is the curl_exec function doesn't return the data but displays the content directly.

可能是什么问题?我可以设置一些选项来避免这种行为吗?

What could be the problem? Can I set some of the options to avoid such behaviour?

推荐答案

我敢打赌这与对等方发送的错误 Content-Length 标头有关.我的建议是让 curl 自己设置长度.

I bet this is related to a wrong Content-Length header sent by the peer. My advice is to let curl set the length by itself.
