php curl 分离header和body信息
php中可以通过curl来模拟http请求,同时可以获取http response header和body,当然也设置参数可以只获取其中的某一个,当设置同时获取response header和body时候,它们会一同作为结果返回,这时需要我们自己来分离它们。
下面代码是模拟向google一个http GET请求,代码如下:
<?php
function httpGet() {
$url = 'http://www.google.com.hk';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, TRUE); //表示需要response header
curl_setopt($ch, CURLOPT_NOBODY, FALSE); //表示需要response body
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
$result = curl_exec($ch);
if (curl_getinfo($ch, CURLINFO_HTTP_CODE) == '200') {
return $result;
}
return NULL;
}
?>调用上述方法后看到如下类似输出：
HTTP/1.1 200 OK
