curl之get請求

public function sendGetRequest($url){   
        
        // 1. 初始化
        $ch = curl_init();
        // 2. 設置選項,包括URL
        curl_setopt($ch,CURLOPT_URL,$url);
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
        curl_setopt($ch,CURLOPT_HEADER,0);

        // 3. 執行並獲取
        $ret = curl_exec($ch);
        if (!$ret) {
            $errMsg   = curl_error($ch);
            $retArr   = array();
            $retArr   = array (
                "status_code" => 0,
                "msg"         => "接口 $url 網絡故障, 錯誤信息: " . $errMsg,
                "data"        => $url
            );

            $error = 'curl get ' . $url . ' failed, '  . curl_error($ch);
        }else{
            $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
            $retArr   = array (
                "status_code" => $httpCode,
                "msg"         => '成功調用接口 ' . $url,
                "data"        => $ret
            );
        }

        curl_close($ch);
        return $retArr;
    }

程序裏發送get請求的時候，參數中的中文要urlencode或者http_build_query。
