为什么 cURL 不能通过 url 连接到 api？

  • 772

使用 cURL 安装了本地服务器。

[![在此处输入图像描述][1]][1]

我想连接到第三方服务的 api。我正在使用以下脚本：

class Auth {
public $url = "https://xxxxxxxxxxxxxxxxx";
public $credentials = [
    'user_name' => 'xxxxxxxxxxxx',
    'user_pass' => 'xxxxxxxxxxxx',
    'product_code' => 'xxx'
    ];

    function moveaway () {
        $access = json_encode($credentials);
        $getting = curl_init($url);
        curl_setopt($getting, CURLOPT_POST, 1);
        curl_setopt($getting, CURLOPT_POSTFIELDS, $access);
        curl_setopt($getting, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($getting, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($getting, CURLOPT_HEADER, false);
        $output = curl_exec($getting);
        curl_close($getting);
        echo $output;
    }
}

由于某种原因，此代码未连接到 api。控制台中没有服务器响应，但也没有错误：

请告诉我，我做错了什么！？

  1. Best Answer

    可以这样做。

    $access = json_encode($this->credentials);
$getting = curl_init($this->url);

    你如何访问类属性？$url) $this->url 可能会更好。向方法 public function moveaway () {} 添加说明符，如果您不公开使用它们，则将属性设为私有，例如重新定义...

  2. 简而言之，错误在于您正在访问仅对该函数可见的类函数内的变量。改变

    $access = json_encode($credentials);

    在

    $access = json_encode($this->credentials);

    好吧，最好将类重写为更正确的版本。像这样的东西

    class Auth {
     private $url = null;
     private $user_name = null;
     private $user_pass = null;
     private $product_code = null;

     public function setURL( $url ) {
         $this->url = $url;
     }
     public function getURL() {
         return $this->url;
     }

     public function setUserName( $user_name ) {
         $this->user_name = $user_name;
     }
     public function getUserName() {
         return $this->user_name;
     }

     public function setUserPass( $user_pass ) {
         $this->user_pass = $user_pass;
     }
     public function getUserPass() {
         return $this->user_pass;
     }

     public function setProductCode( $product_code ) {
         $this->product_code = $product_code;
     }
     public function getProductCode() {
         return $this->product_code;
     }

    public function moveAway () {
        $ch = curl_init($this->url);
        curl_setopt($ch ,CURLOPT_HTTPHEADER, ["Accept:application/json", "Content-Type: application/json"]);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode([
            'user_name' => $this->user_name,
            'user_pass' => $this->user_pass,
            'product_code' => $this->product_code
        ]));
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_HEADER, false);//<-- true for debug headers
        curl_setopt($ch, CURLOPT_USERAGENT, "curl/7.58.0"); //<-- set another useragent if need
        //curl_setopt($ch, CURLOPT_VERBOSE, 1); //<-- debug
        $output = curl_exec($ch);
        curl_close($ch);
        echo $output;
    }
}

    通过сеттеры暴露所有变量，然后调用moveAway
