try/catch with CURL, Google shortener API?

本文关键字：程序 API 谷歌捕获 CURL 尝试 | 更新日期: 2023-09-27

我正在使用Google Shortener API，需要处理错误：

https://developers.google.com/url-shortener/v1/getting_started#errors

这是我的代码：

public function shorten($url, $extended = false)
{
    # Check buffer
    if ( !$extended && !$this->extended && !empty(self::$buffer[$url]) ) {
        return self::$buffer[$url];
    }
    # Payload
    $data = array( 'longUrl' => $url );
    $data_string = '{ "longUrl": "'.$url.'" }';
    # Set cURL options
    curl_setopt($this->ch, CURLOPT_POST, count($data));
    curl_setopt($this->ch, CURLOPT_POSTFIELDS, $data_string);
    curl_setopt($this->ch, CURLOPT_HTTPHEADER, Array('Content-Type: application/json'));
    if ( $extended || $this->extended) {
        return json_decode(curl_exec($this->ch));
    } else {
        $ret = json_decode(curl_exec($this->ch))->id;
        self::$buffer[$url] = $ret;
        return $ret;
    }
}

但我真的不知道如何尝试/捕捉谷歌返回的错误消息？

您有一个多维数组，因此您可以循环遍历该数组，或者更简单的方法是简单地检查错误字段和代码字段是否存在

    if ( $extended || $this->extended) {
                $result = json_decode(curl_exec($this->ch));
               if(array_key_exists('errors',$result) && array_key_exists('code',$result)){
                    //handle error
                       }
                    else{
                   //do stuff
                       }
        } else {
                $ret = json_decode(curl_exec($this->ch))->id;
                self::$buffer[$url] = $ret;
                return $ret;
        }
