curl get post 数据

记一次yii下curl排错经验：

要求需要通过header传送token，数据传入方式为application/json

1.postman方式调取，没有问题，参数已json形式传过去-{}

2.原生PHP调取

        $url = Yii::$app->params['get_auto_test_detail_list'];
        $params['start'] = 0;
        $params['count'] = 10;
        $ch = curl_init();
        curl_setopt($ch,CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($params));   //不是json_encode(http_build_query($params))
        $a = "Bearer eyJ0eXAiOi";            
        curl_setopt($ch,CURLOPT_HTTPHEADER, array("Authorization: " .$a, "Content-Type:application/json"));  //数组形式，参数名字是CURLOPT_HTTPHEADER
        $output = curl_exec($ch);
        if($output === FALSE ){
             echo "CURL Error:".curl_error($ch);
        }
        curl_close($ch);
        var_dump($output);die;

3.Yii 通过Curl类 _simple_call()方法调取，

public function getAutoTestDetailList()
{
        $url = Yii::$app->params['get_auto_test_detail_list'];
        $params['start'] = ;
        $params['count'] = ;
        $curl = new Curl();
        $options['HTTPHEADER'] = array("Authorization:" .self::TOKEN, "Content-Type:" .self::CONTENT_TYPE);  //封装方法里面对httpheader有拼接,调用set_opt_array()
        $result = $curl->_simple_call("post", $url, json_encode($params), $options);  //参数json形式
        if ($result !== false) {
            $result = json_decode($result, true);
        }
        echo "<pre>";var_dump($result);echo "</pre>";
}

1.get方式传值

 function  testGet(){
         $ch = curl_init ();                              //初始化一个cURL会话
         $url = "127.0.0.1/testPage?test=test";  
 4
         curl_setopt ( $ch, CURLOPT_URL, $url );          //设置一个cURL传输选项，url链接
         curl_setopt ( $ch, CURLOPT_HEADER, 0 );          //是否传头信息
 7
 8         curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );  //是否流，获取数据返回，不设置默认将抓取数据的结果返回，成功返回bool(true),失败返回bool(false)
         $content = curl_exec ( $ch );   　　　　　　　　　　//关闭链接
         var_dump($content);

 }

 function  testPage(){

       echo  $_GET['test'];
 }

2.post方式传值

function  testPost(){ 

        $ch = curl_init ();
        $data["test"] = "test";
        $url = "127.0.0.1/test";
        curl_setopt ( $ch, CURLOPT_URL, $url );
        curl_setopt ( $ch, CURLOPT_POST, 1 );　//如果你想PHP去做一个正规的HTTP POST，设置这个选项为一个非零值。这个POST是普通的 application/x-www-from-urlencoded 类型，多数被HTML表单使用
        curl_setopt ( $ch, CURLOPT_HEADER, 0 );
        curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
        curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );   //post方式传数据
        $content = curl_exec ( $ch );
        curl_close ( $ch );

        var_dump($content);
}

function  testPage(){

        echo $_POST['test'];
}    

3.关于php curl 编码方式 的content-type  是  multipart/form-data 还是 application/x-www-form-urlencoded

传递一个数组到CURLOPT_POSTFIELDS，CURL会把数据编码成 multipart/form-data，而传递一个URL-encoded字符串时，数据会被编码成 application/x-www-form-urlencoded"。

http://www.phperz.com/article/14/1031/32420.html  这个链接说了下两种编码的区别。而如果将post方式传输的数据 惊醒http_build_query($data) 后 ，再传输就是

application/x-www-form-urlencoded 格式 。

 

4.一个较为ok的例子

 class RemoteToolService {

     static public $timeout = 10;

     /**
      * send request
      *
      * @param  $url
      * @param  $type
      * @param  $args
      * @param  $charset
      *
      * @Returns
      */
     public function send($url, $type, $args, $charset = 'utf-8') {
         if ($type == 'post') {
             $returnValue = $this->_post($url, $args, $charset);
         } else {
             $url .= '?' . http_build_query($args);
             $returnValue = $this->_get($url, $charset);
         }
         return $returnValue;
     }

     private function _post($url, $arguments, $charset = 'utf-8') {
         if (is_array($arguments)) {
             $postData = http_build_query($arguments);
         } else {
             $postData = $arguments;
         }

         $ch = curl_init();
         curl_setopt($ch, CURLOPT_DNS_USE_GLOBAL_CACHE, false);
         curl_setopt($ch, CURLOPT_URL, $url);
         curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
         curl_setopt($ch, CURLOPT_POST, 1);
         curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
         curl_setopt($ch, CURLOPT_TIMEOUT, self::$timeout);
         curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, self::$timeout);

         $returnValue = curl_exec($ch);
         curl_close($ch);
         if ($charset != 'utf-8') {
             $returnValue = iconv($charset, 'utf-8', $returnValue);
         }
         return $returnValue;
     }

     private function _get($url, $charset = 'utf-8') {
         $ch = curl_init();
         curl_setopt($ch, CURLOPT_URL, $url);
         curl_setopt($ch, CURLOPT_HEADER, 0);
         curl_setopt($ch, CURLOPT_TIMEOUT, self::$timeout);
         curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, self::$timeout);
         curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
         curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
         $returnValue = curl_exec($ch);
         curl_close($ch);
         if ($charset != 'utf-8') {
             $returnValue = iconv($charset, 'utf-8', $returnValue);
         }
         return $returnValue;
     }

     public function sendJson($url, $arguments, $charset = 'utf-8') {
         if (is_array($arguments)) {
             $postData = json_encode($arguments);
         } else {
             $postData = $arguments;
         }

         $ch = curl_init();
         curl_setopt($ch, CURLOPT_DNS_USE_GLOBAL_CACHE, false);
         curl_setopt($ch, CURLOPT_URL, $url);
         curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
         curl_setopt($ch, CURLOPT_POST, 1);
         curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
         curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json', 'Content-Length:' . strlen($postData)));
         curl_setopt($ch, CURLOPT_TIMEOUT, self::$timeout);
         curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, self::$timeout);

         $returnValue = curl_exec($ch);
         curl_close($ch);
         if ($charset != 'utf-8') {
             $returnValue = iconv($charset, 'utf-8', $returnValue);
         }
         return $returnValue;
     }

 }

 $params = array(
             'uid' => $uid,
             'incr' => $incr,
             'type' => $type,
             'source' => $scorce,
             'sign' => $sKey

 $ob = new  RemoteToolService();
 $data =$ob->send($callUrl, 'post', $params);

对curl的了解还是不太清晰，只是暂时能用。。
