Question

我正在尝试从嵌入式设备向我的网络服务器发送POST请求，但是网络服务器会向我返回错误400.

这是我发送到服务器端口80的请求：

POST /api_back.php HTTP/1.1
Host: mysubdomain.mydomain.com
User-Agent: AppleWebKit/531.21.10
Accept: */*
Content-Type: application/x-www-form-urlencoded
Cache-Control: no-cache
Accept-Charset: utf-8, us-ascii
Pragma: no-cache

data=10,1,1,1,1,-48%0D%0A10,1,1,1,1,-48%0D%0A10,1,1,1,1,-47%0D%0A10,1,1,1,1,-48%0D%0A10,1,1,1,1,-48%0D%0A10,1,1,1,1,-47%0D%0A10,1,1,1,1,-47%0D%0A

然后我收到以下回复：

 instead of REQUEST_URI, we could show absolute URL via:
 http://HTTP_HOST/REQUEST_URI
    but what if its https:// or other protocol?
    
    SERVER_PORT_SECURE doesn't seem to be used
    SERVER_PORT logic would break if they use alternate ports

错误似乎表明主机名或请求uri是错误的，所以我也尝试了POST链接中的整个URL：

POST http://mysubdomain.mydomain.com/api_back.php HTTP/1.1
Host: mysubdomain.mydomain.com
...

也没有运气。我试过的其他事情

不同的用户代理
HTTP / 1.0
主机标头中没有子域

所有这些似乎都会导致同样的错误。

有人提出建议吗？我错过了标题吗？标题中是否有错误？

非常感谢任何帮助或建议！

对于那些寻找类似问题的人;问题是，逗号显然不是帖子请求中的有效字符，urlencode逗号和生活再次好：）

HTTP POST请求返回400，未使用SERVER_PORT_SECURE
