C++获取网页数据时的505错误

包头少信息 ：添加包头信息

正常情况下，ucenter请求程序应该返回的是”1″, 用浏览器获取到的是正常的。然而通过api调用返回的是一串乱码：转换成16进制为“ 1f8b 0800 0000 0000 0003 3204 0000 00ff  ff03 00b7 efdc 8301 0000 000a”。

网上搜索了一下发现“1f8b 0800 0000 0000”应该是gzip的文件头，所以更加确定了问题出现在gzip上。

在尝试了将nginx关闭gzip后，发现问题依旧。然后发现原来php启用了，自动gzip。于是在php.ini中将 zlib.output_compression = Off 关掉后，问题解决！//打开HTTP请求句柄
