php post请求和jquery中post请求有什么不同吗?
自己写了一个php的socket http请求,
public function sendpost($postType='POST') { $url = $this->postURL; $data = $this->postData == '' ? array() : $this->postData; //先解析url $url = parse_url($url); $url_port = !isset($url['port']) ? (($url['scheme'] == 'http') ? 80 : 443) : $url['port']; if (!$url) { $this->errMessage = "couldn't parse url"; return false; } //将参数拼成URL key1=value1&key2=value2 的形式 $encoded = ""; while (list($k, $v) = each($data)) { $encoded .= ($encoded ? '&' : ''); $encoded .= rawurlencode($k)."=".rawurlencode($v); } //echo $encoded;exit; $len = strlen($encoded); //拼上http头 $out = "{$postType} ".$url['path'].(isset($url['query']) ? ('?'.$url['query']) : '')." HTTP/1.1\r\n"; $out .= "Host:".$url['host']."\r\n"; $out .= "Content-type: application/x-www-form-urlencoded\r\n"; $out .= "Connection: Close\r\n"; $out .= "Content-Length: $len\r\n"; $out .= "\r\n"; $out .= $encoded."\r\n"; //打开一个sock $fp = @fsockopen($url['host'], $url_port); $line = ""; if (!$fp) { $this->errMessage = "$errstr($errno)\n"; return false; } else { fwrite($fp,$out); while (!feof($fp)) { $line .= fgets($fp, 2048); } } //去掉头文件 if ($line) { $body = stristr($line, "\r\n\r\n"); $body =substr($body, 4, strlen($body)); $line = $body; } fclose($fp); return $line; }
$.ajax({ type : "POST", cache : false, url : _url, data : _data, dataType : 'json', success : function(data) { } });

[解决办法]
另外,https你的代码是无力的,必须用php支持的context参数利用stream_context_create配合file_get_contents之类的使用或者fopen之类的使用,或者直接用curl。

错,刚才看了一下,fsockopen支持SSL和TSL,这样:
hostname
If OpenSSL support is installed, you may prefix the hostname with either ssl:// or tls:// to use an SSL or TLS client connection over TCP/IP to connect to the remote host.
