我几乎查看了所有涉及"发布"的stackoverflow页面,google页面等。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。我似乎无法理解我做错了什么。
我正在尝试将照片从我的桌面上传到我的网络服务器上,我得到一个" 200 ok"消息,然后在身体中我得到源+" 400 Bad Response"
如果你能够找到它为什么似乎不起作用我将会如此伟大!
我的代码:(我追加MemoryBuffer的原因是因为如果我使用相等的运算符data.size()将返回类似500的长度,这将是不正确的。我告诉Content-Size:didn&# 39;对于multipart / form-data来说很重要,这就是我省略它的原因)

答案 0 :(得分:0)
您的HTTP
请求缺少Content-Length
标题。
参见RFC 2616的第4.3节:
请求中存在消息正文 包含Content-Length或Transfer-Encoding标头字段 请求的消息标题。
您的请求包含一个消息正文(显然)。因此,它必须具有这两个标头中的一个。由于此服务器为HTTP/1.1
,因此Transfer-Encoding
标题也可供您选择。
