libcUrl 错误的请求。似乎 POST 正文未发送，仅发送标题

Question

我使用此选项：

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());

我尝试按照 他们的手册将文件上传到 Youtube ，我的请求的 header 和 body 与手册中的完全相同。

我收到错误请求，详细模式显示以下内容：

* 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。

Answer 1

我的错误是由于 POST 正文中的错误造成的。所以这个 cUrl 选项是使用 header 形成 POST 请求的正确方法。
