php实现模拟post请求用法实例
本文实例讲述了php实现模拟post请求的方法。分享给大家供大家参考。具体如下：
class
Request{
public
static
function
post($url,
$post_data
=
'',
$timeout
=
5){//curl
$ch
=
curl_init();
curl_setopt
($ch,
CURLOPT_URL,
$url);
curl_setopt
($ch,
CURLOPT_POST,
1);
if($post_data
!=
''){
curl_setopt($ch,
CURLOPT_POSTFIELDS,
$post_data);
}
curl_setopt
($ch,
CURLOPT_RETURNTRANSFER,
1);
curl_setopt
($ch,
CURLOPT_CONNECTTIMEOUT,
$timeout);
curl_setopt($ch,
CURLOPT_HEADER,
false);
$file_contents
=
curl_exec($ch);
curl_close($ch);
return
$file_contents;
}
public
static
function
post2($url,
$data=array()){//file_get_content
$postdata
=
http_build_query(
$data
);
$opts
=
array('http'
=
array(
'method'
=
'POST',
'header'
=
'Content-type:
application/x-www-form-urlencoded',
'content'
=
$postdata
)
);
$context
=
stream_context_create($opts);
$result
=
file_get_contents($url,
false,
$context);
return
$result;
}
public
static
function
post3($host,$path,$query,$others=''){//fsocket
$post="POST
$path
HTTP/1.1rnHost:
$hostrn";
$post.="Content-type:
application/x-www-form-";
$post.="urlencodedrn${others}";
$post.="User-Agent:
Mozilla
4.0rnContent-length:
";
$post.=strlen($query)."rnConnection:
closernrn$query";
$h=fsockopen($host,80);
fwrite($h,$post);
for($a=0,$r='';!$a;){
$b=fread($h,8192);
$r.=$b;
$a=(($b=='')?1:0);
}
fclose($h);
return
$r;
}
}
$url='http://******/con/Inter.php';
$data=Request::post($url,array('api'='tag_list'));
$data2=Request::post2($url,array('api'='tag_list'));
echo
$data;

php怎么以post方式发送数据
:用PHP向服务器发送HTTP的POST请求,代码如下:?php/***发送post请求*@paramstring$url请求地址*@paramarray$post_datapost键值对数据*@returnstring*/.
怎么用PHP发送POST请求
PHP发送POST请求的三种方式
class Request{
public static function post($url, $post_data = '', $timeout = 5){//curl
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_POST, 1);
if($post_data != ''){
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
}
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_HEADER, false);
$file_contents = curl_exec($ch);
curl_close($ch);
return $file_contents;
}
public static function post2($url, $data){//file_get_content
$postdata = http_build_query(
$data
);
$opts = array('http' =
array(
'method' = 'POST',
'header' = 'Content-type: application/x-www-form-urlencoded',
'content' = $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents($url, false, $context);
return $result;
}
public static function post3($host,$path,$query,$others=''){//fsocket
$post="POST $path HTTP/1.1rnHost: $hostrn";
$post.="Content-type: application/x-www-form-";
$post.="urlencodedrn${others}";
$post.="User-Agent: Mozilla 4.0rnContent-length: ";
$post.=strlen($query)."rnConnection: closernrn$query";
$h=fsockopen($host,80);
fwrite($h,$post);
for($a=0,$r='';!$a;){
$b=fread($h,8192);
$r.=$b;
$a=(($b=='')?1:0);
}
fclose($h);
return $r;
}
}
如何用php向服务器发送post请求
用PHP向服务器发送HTTP的POST请求，代码如下：
?php
/**
* 发送post请求
* @param string $url 请求地址
* @param array $post_data post键值对数据
* @return string
*/
function send_post($url, $post_data) {
$postdata = http_build_query($post_data);
$options = array(
'http' = array(
'method' = 'POST',
'header' = 'Content-type:application/x-www-form-urlencoded',
'content' = $postdata,
'timeout' = 15 * 60 // 超时时间（单位:s）
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
return $result;
}
使用的时候直接调用上面定义的send_post方法：
$post_data = array(
'username' = 'username',
'password' = 'password'
);
send_post('网址', $post_data);
PHP中怎样发送post请求并获取网页？
$post='POST数据';
// 初始化
$curl = curl_init('URL');
$header = array();
$header[] = 'User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.90 Safari/537.36';
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
// 不输出header头信息
curl_setopt($curl, CURLOPT_HEADER, 0);
// 保存到字符串而不是输出
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
// post数据
curl_setopt($curl, CURLOPT_POST, 1);
// 请求数据
curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
// 是否抓取跳转后的页面
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
$response = curl_exec($curl);
curl_close($curl);
echo $response;
