c++ -上传文件到web服务器与多部分表单数据| WinSock2
C++ - Uploading file to webserver with multipart form-data | WinSock2
我看了几乎每一个stackoverflow页面，google页面等，包括"发布"一个文件到web服务器，我甚至下载了FireBug来检查发送的内容，我几乎完全复制了它。我似乎不明白我做错了什么。
我试图从我的桌面上传一张照片到我的web服务器，我得到一个"200 ok"消息，然后在正文中我得到源+"400坏响应"
如果你能找出为什么它似乎不起作用，我将是如此伟大!
我的代码:(我追加我的MemoryBuffer的原因是，如果我使用相等的操作符data.size()将返回像500这样的长度，这将是不正确的。另外，我被告知Content-Size:对于multipart/form-data并不重要，所以我省略了它)

您的HTTP请求缺少Content-Length标头。
参见RFC 2616第4.3节:
请求中是否存在消息体由包含内容长度或传输编码头字段请求消息头。
你的请求包含一个消息体(很明显)。因此，它必须具有这两个头中的一个。由于此服务器是HTTP/1.1，因此Transfer-Encoding标头也是您的选项。
