1，GET请求

/**
 *  GET
 */
public  function php_do_Url_GET($url,$params){

    $url = "{$url}?" . http_build_query ( $params );
    $ch = curl_init ();
    curl_setopt ( $ch, CURLOPT_URL, $url );
    curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt ( $ch, CURLOPT_CUSTOMREQUEST, 'GET' );
    curl_setopt ( $ch, CURLOPT_TIMEOUT, 60 );
    curl_setopt ( $ch, CURLOPT_POSTFIELDS, $params );
    $result = curl_exec ( $ch );
    curl_close ( $ch );

    return $result;
}

2，POST请求

/**
* POST
*/
public  function  php_do_url_POST($url,$params,$headers){

    $ch = curl_init ();

    curl_setopt ( $ch, CURLOPT_URL, $url );
    curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt ( $ch, CURLOPT_CUSTOMREQUEST, 'POST' );
    curl_setopt ( $ch, CURLOPT_POSTFIELDS, $params );
    curl_setopt ( $ch, CURLOPT_HTTPHEADER, $headers );
    curl_setopt ( $ch, CURLOPT_TIMEOUT, 60 );

    $result = curl_exec ( $ch );
    curl_close ( $ch );

    return $result;
}

3，heaer中Content-Type注意事项

    //application/x-www-form-urlencoded 格式请求转http_build_query

    $postData = http_build_query($params);
    //application/json;charset=utf-8 请求转json_encode
    $jsonparams=json_encode($params);

4，使用实例 post实例

 $url = "http://api.cn.ronghub.com/user/getToken.json";
    $params = array("userId"=>$userId,"name"=>$name,"portraitUri"=>$portraitUri);
    //application/x-www-form-urlencoded 格式请求转http_build_query

    $postData = http_build_query($params);
    //application/json;charset=utf-8 请求转json_encode
//        $jsonparams=json_encode($params);
    $headers=array(

        "Content-Type: application/x-www-form-urlencoded",
        "Timestamp: " . $timestamp,
        "App-Key: " . $appKey,
        "Nonce: " . $nonce,
        "Signature:".$local_signature,
        'Content-Length: ' . strlen($postData)
    );

    $requestObj = new PhpUrlReqest();
    $result = $requestObj->php_do_url_POST($url,$postData,$headers);
