php 模拟post提交请求,调用接口

有两种写法可以调用接口获取返回数据(如下):

写法 一:


/**
 * 模拟post进行url请求
 * @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,$postUrl);//抓取指定网页
    curl_setopt($ch, CURLOPT_HEADER, 0);//设置header
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
    curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
    curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
    $data = curl_exec($ch);//运行curl
    curl_close($ch);
        
    return $data;
}

//调用示例,这样就提交请求,并且获取请求结果了。一般返回的结果是json格式的。

这里的post是拼接出来的。

function testAction(){
    $url = 'http://mobile.jschina.com.cn/jschina/register.php';
    $post_data['appid']       = 'XXXXXXXX';
    $post_data['appkey']      = 'XXXXXXXXXXXXXXXX';
    $post_data['member_name'] = 'XXXXXXXX';
    $post_data['password']    = 'XXXXXXXX';
    $post_data['email']    = '[email protected]';
    $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);
}

写法 二:

将拼接也封装了起来,这样调用的时候就更简洁了。

/**
 * 模拟post进行url请求
 * @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,$postUrl);//抓取指定网页
    curl_setopt($ch, CURLOPT_HEADER, 0);//设置header
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
    curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
    curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
    $data = curl_exec($ch);//运行curl
    curl_close($ch);    
    return $data;
}

//调用接口,获取返回数据

function testAction(){
    $url = 'http://mobile.jschina.com.cn/jschina/register.php';
    $post_data['appid']       = 'XXXXXXXX';
    $post_data['appkey']      = 'XXXXXXXXXXXXXXXX';
    $post_data['member_name'] = 'XXXXXXXX';
    $post_data['password']    = 'XXXXXXXX';
    $post_data['email']    = '[email protected]';
    //$post_data = array();
    $res = $this->request_post($url, $post_data);       
    print_r($res);
}
