为什么我的卷曲出现超时错误？

Question

我的代码是：

public function sendPostData()
    {
        $url = "http://$this->cPdomain/$this->serverScriptFile";
        $cPUser = $this->cPanel->user;
        $data = "db=$this->newDatabaseName&user=$this->newDatabaseUser&password=$this->newDatabasePassword&host=$this->serverHost&prefix=$this->newDatabasePrefix&cPUser=$cPUser";

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        // curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 20);

        // Receive server response ...
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        $server_output = curl_exec($ch);
        $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

        $responseCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
        $curlData = [
            'url' => $url,
            'cPUser' => $cPUser,
            'data' => $data,
            'HTTP Error' => $responseCode,
            'HTTP code' => $httpCode
            ];
        $this->setLog($curlData, 'curl_data.txt');

        if ($server_output === false) {
            $this->setLog("CURL Error: " . curl_error($ch), 'curl_err.txt');
            return 0;
        }

        curl_close ($ch);

        return 1;
    }

在 HostBill 上创建帐户后，我使用运行某些功能的代码，但有时我的curl 中会出现超时错误。为什么？

你的字符串插值是完全错误的。对象属性必须括在大括号内。

$url = "http://{$this->cPdomain}/{$this->serverScriptFile}";

需要在所有代码行中完成。

由于这是一个 POST 请求，您应该提供一个数组：

$data = [
    'db' => $this->newDatabaseName,
    'user' => $this->newDatabaseUser,
    'password' => $this->newDatabasePassword,
    'host' => $this->serverHost,
    'prefix' => $this->newDatabasePrefix,
    'cPUser' => $cPUser
];
