【问题描述】：
我使用这个选项：
curl_easy_setopt(curl, CURLOPT_URL, urlUpload);
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_easy_setopt(curl, CURLOPT_ERRORBUFFER, errorBuffer);
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
curl_easy_setopt(curl, CURLOPT_POST, 1);
curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE_LARGE, body.length());
curl_easy_setopt(curl, CURLOPT_HEADER, 1);
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, header);
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, body.c_str());
我正在尝试按照their manual 将文件上传到 Youtube，我的请求的标题和正文与手册中的完全相同。
我收到错误请求，详细模式显示如下：
* About to connect() to uploads.gdata.youtube.com port 80 (#0)

似乎由于某种原因根本没有发送正文，有人可以帮助我吗？
更新：
当我禁用 Expect: 标头时，我仍然收到错误请求。

【问题讨论】：
-
正文未发送，因为服务器未使用
100: Continue标头进行响应。它没有回答可能是因为它不理解Expect标头。尝试禁用它（使用CURLOPT_HTTPHEADER）。 -
@n.m.我禁用了。我也收到了错误请求，我更新了我的问题。

此外，您的换行符似乎有误，或类似情况。看看请求中的 POST 标头是如何在输出中以
>字符开头的，所有其他行的开头都没有>。通常，所有标题都应以>字符开头。所有回复标题前面都有一个<字符，就像它们应该的那样。我建议您使用tcpdump或wireshark来嗅探流量并验证所有行尾是否正确。
