《PHP應(yīng)用：PHP模擬post提交數(shù)據(jù)方法匯總》要點(diǎn)：
本文介紹了PHP應(yīng)用：PHP模擬post提交數(shù)據(jù)方法匯總，希望對(duì)您有用。如果有疑問(wèn)，可以聯(lián)系我們。
使用php模擬post傳值雖然在日常生活中用到的不是很多,但是在某些場(chǎng)合還是經(jīng)常用到的.下面維易PHP小編給大家整理了三種php模擬post傳值的方法,file_get_contents、curl和socket.PHP應(yīng)用
第一種：file_get_contents來(lái)模擬postPHP應(yīng)用
<php
function file_get_contents_post($url, $post){
$options = array(
‘http‘=> array(
‘method‘=>‘POST‘,
‘content‘=> http_build_query($post),
),
);
$result = file_get_contents($url,false, stream_context_create($options));
return $result;
}
$data = file_get_contents_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));
var_dump($data);
第二種：curl模擬postPHP應(yīng)用
<php
function curl_post($url, $post){
$options = array(
CURLOPT_RETURNTRANSFER =>true,
CURLOPT_HEADER =>false,
CURLOPT_POST =>true,
CURLOPT_POSTFIELDS => $post,
);
$ch = curl_init($url);
curl_setopt_array($ch, $options);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
$data = curl_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));
var_dump($data);
第三種：socket來(lái)模擬postPHP應(yīng)用
<php
function socket_post($url, $post){
$urls = parse_url($url);
if(!isset($urls[‘port‘])){
$urls[‘port‘]=80;
}
$fp = fsockopen($urls[‘host‘], $urls[‘port‘], $errno, $errstr);
if(!$fp){
echo "$errno, $errstr";
exit();
}
$post = http_build_query($post);
$length = strlen($post);
$header =<<<HEADER
<span class="Apple-tab-span" style="white-space:pre"></span>POST {$urls[‘path‘]} HTTP/1.1
<span class="Apple-tab-span" style="white-space:pre"></span>Host:{$urls[‘host‘]}
<span class="Apple-tab-span" style="white-space:pre"></span>Content-Type: application/x-www-form-urlencoded
<span class="Apple-tab-span" style="white-space:pre"></span>Content-Length:{$length}
<span class="Apple-tab-span" style="white-space:pre"></span>Connection: close
<span class="Apple-tab-span" style="white-space:pre"></span>{$post}
<span class="Apple-tab-span" style="white-space:pre"></span>HEADER;
fwrite($fp, $header);
$result =‘‘;
while(!feof($fp)){
$result .= fread($fp,512);
}
$result = explode("\r\n\r\n", $result,2);
return $result[1];
}
$data = socket_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));
var_dump($data);
上面這三種方法最后看到的內(nèi)容都是一樣的,都可以得到post的傳值；但是在是用socket的時(shí)候,發(fā)送header信息時(shí)必須要注意header的完整信息,比如content type和content length必須要有,connection: close和post數(shù)據(jù)之間要空一行,等等；而通過(guò)socket取得的內(nèi)容是包含了header信息的,要處理一下才能獲得真正的內(nèi)容.PHP應(yīng)用
下面給大家說(shuō)下php模擬post提交請(qǐng)求,調(diào)用接口 PHP應(yīng)用
/**
* 模擬post進(jìn)行url請(qǐng)求
* @param string $url
* @param string $param
*/
function request_post($url = '', $param = '') {
if (empty($url) || empty($param)) {
return false;
}
$postUrl = $url;
$curlPost = $param;
$ch = curl_init();//初始化curl
curl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定網(wǎng)頁(yè)
curl_setopt($ch, CURLOPT_HEADER, 0);//設(shè)置header
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求結(jié)果為字符串且輸出到屏幕上
curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
$data = curl_exec($ch);//運(yùn)行curl
curl_close($ch);
return $data;
}
這是方法,
PHP應(yīng)用
下面是具體的調(diào)用案例.
PHP應(yīng)用
function testAction(){
$url = 'http://mobile.jschina.com.cn/jschina/register.php';
$post_data['appid'] = '10';
$post_data['appkey'] = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';
$post_data['member_name'] = 'zsjs123';
$post_data['password'] = '123456';
$post_data['email'] = 'zsjs123@126.com';
$o = "";
foreach ( $post_data as $k => $v )
{
$o.= "$k=" . urlencode( $v ). "&" ;
}
$post_data = substr($o,0,-1);
$res = $this->request_post($url, $post_data);
print_r($res);
}
這樣就提交請(qǐng)求,并且獲取請(qǐng)求結(jié)果了.一般返回的結(jié)果是json格式的.
PHP應(yīng)用
這里的post是拼接出來(lái)的.
PHP應(yīng)用
也可以改造成下面的方式.
PHP應(yīng)用
/**
* 模擬post進(jìn)行url請(qǐng)求
* @param string $url
* @param array $post_data
*/
function request_post($url = '', $post_data = array()) {
if (empty($url) || empty($post_data)) {
return false;
}
$o = "";
foreach ( $post_data as $k => $v )
{
$o.= "$k=" . urlencode( $v ). "&" ;
}
$post_data = substr($o,0,-1);
$postUrl = $url;
$curlPost = $post_data;
$ch = curl_init();//初始化curl
curl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定網(wǎng)頁(yè)
curl_setopt($ch, CURLOPT_HEADER, 0);//設(shè)置header
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求結(jié)果為字符串且輸出到屏幕上
curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
$data = curl_exec($ch);//運(yùn)行curl
curl_close($ch);
return $data;
}
將拼接也封裝了起來(lái),這樣調(diào)用的時(shí)候就更簡(jiǎn)潔了.
PHP應(yīng)用
function testAction(){
$url = 'http://mobile.jschina.com.cn/jschina/register.php';
$post_data['appid'] = '10';
$post_data['appkey'] = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';
$post_data['member_name'] = 'zsjs124';
$post_data['password'] = '123456';
$post_data['email'] = 'zsjs124@126.com';
//$post_data = array();
$res = $this->request_post($url, $post_data);
print_r($res);
}
