CURL解析超时的解决方案
|
背景:项目中需要在抓取纷享销客CRM图片上传到OSS,调用OssClient.php时,容易发生解析超时(多重试几次就ok)。 错误提示: [2019-04-08 19:41:01] lumen.DEBUG: 出错文件:/home/zrj/www/admin/yundou-admin/vendor/aliyuncs/oss-sdk-php/src/OSS/OssClient.php [2019-04-08 19:41:01] lumen.DEBUG: 出错编码:0 [2019-04-08 19:41:01] lumen.DEBUG: 出错行号:2187 [2019-04-08 19:41:01] lumen.DEBUG: 出错信息:RequestCoreException: cURL resource: Resource id #371; cURL error: Resolving timed out after 10521 milliseconds (28) Resolving timed out after 10521 milliseconds (28) 源码分析: try {
$ossClient = new OssClient(self::$accessKeyId, self::$accessKeySecret, self::$endpoint);
$ossClient->uploadFile(self::$bucket, $ossFileName, $localhostFileName);//上传文件
$ossClient->putBucketAcl(self::$bucket, OssClient::OSS_ACL_TYPE_PUBLIC_READ);
} catch (OssException $e) { self::debugException($e); throw new Exception("上传oss失败:" . $e->getMessage(), $e->getCode());
}1.实例化OssClient客户端后,调用uploadFile方法。 /**
* 上传本地文件
*
* @param string $bucket bucket名称
* @param string $object object名称
* @param string $file 本地文件路径
* @param array $options
* @return null
* @throws OssException
*/
public function uploadFile($bucket, $object, $file, $options = NULL)
{
......
$response = $this->auth($options);
$result = new PutSetDeleteResult($response); return $result->getData();
}3.auth中调用RequestCore类创建请求 /**
* 验证并且执行请求,按照OSS Api协议,执行操作
*
* @param array $options
* @return ResponseCore
* @throws OssException
* @throws RequestCore_Exception
*/
private function auth($options)
{
...... //创建请求
$request = new RequestCore($this->requestUrl, $this->requestProxy);
$request->set_useragent($this->generateUserAgent());
...... try {
$request->send_request();
} catch (RequestCore_Exception $e) { throw(new OssException('RequestCoreException: ' . $e->getMessage()));
}
}4.OSSHttpRequestCore类中send_request方法通过CURL发送请求(调用了prep_request准备请求方法) /**
* Sends the request, calling necessary utility functions to update built-in properties.
*
* @param boolean $parse (Optional) Whether to parse the response with ResponseCore or not.
* @return string The resulting unparsed data from the request.
*/
public function send_request($parse = false)
{
set_time_limit(0);
$curl_handle = $this->prep_request(); $this->response = curl_exec($curl_handle); if ($this->response === false) { throw new RequestCore_Exception('cURL resource: ' . (string)$curl_handle . '; cURL error: ' . curl_error($curl_handle) . ' (' . curl_errno($curl_handle) . ')');
}
$parsed_response = $this->process_response($curl_handle, $this->response);
curl_close($curl_handle); if ($parse) { return $parsed_response;
} return $this->response;
}5.最终可以推导出问题出在RequestCore中的CURL。 解决方案: CURLOPT_IPRESOLVE - specify which IP protocol version to use 选项: Default, resolves addresses to all IP versions that your system allows. CURL_IPRESOLVE_V4 Resolve to IPv4 addresses. CURL_IPRESOLVE_V6 Resolve to IPv6 addresses. 这里要注意:默认值(curl没有主动设置CURLOPT_IPRESOLVE选项时,则系统会使用默认值)。 Default, resolves addresses to all IP versions that your system allows. 含义为:默认使用服务器系统允许的所有IP版本来解析地址。 所以,最终的解决方案为显式指定CURL的CURLOPT_IPRESOLVE选项。 curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4); 参考官方CURLOPT_IPRESOLVE (编辑:安卓应用网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
