Php Zend HttpClient更精确的超时？

ZendFramework2的各种http客户端适配器似乎允许连接和读取超时在秒范围内；通过在设置各种超时参数之前将其强制转换为（int）。在我们的组织中，我们通常为生产环境指定较小的连接和读取超时（我们有一个SOA）

但是，php中的套接字级别函数支持超时值（float）以支持次秒超时，并且自PHP5.2.3以来，有一些方法可以使用libcurl支持次秒连接超时。（CULLOPT_连接超时_MS，CULL符合c-ares per）

---

我很高兴进入ZendFramework，以支持更小、更细粒度的超时，但我想先看看这是否是一个“野外”解决的问题。有人使用Zend\Http\Client\Adapter\Socket或\Curl适配器来支持亚秒级的连接和读取超时吗？

我知道两种解决问题的方法。您可以将用作临时修复程序，直到Zend Framework 2自己支持次秒超时

重写

套接字

/

Curl

类

创建模块并从

Socket

/

Curl

类继承，并重写

connect（）

方法以支持亚秒超时

对于

Curl

类，我将在配置数组中添加一个新选项

timeout\u ms

，因此您仍然可以使用旧的

timeout

选项我的代码仅显示超时部分的相关更改。

<?php
use Zend\Http\Client\Adapter\Curl;

class CurlMs extends Curl 
{

  public function connect($host, $port = 80, $secure = false)
  {
    ...
    // Replace the lines with timeout with the following lines.
    if (isset($this->config['timeout_ms'])) {
      // Set timeout milliseconds
      curl_setopt($this->curl, CURLOPT_CONNECTTIMEOUT_MS, $this->config['timeout_ms']);
    } elseif (isset($this->config['timeout'])) {
      // Set timeout
      curl_setopt($this->curl, CURLOPT_CONNECTTIMEOUT, $this->config['timeout']);
    }
    ...
  }
}

<?php
use Zend\Http\Client\Adapter\Socket;

class SocketMs extends Socket 
{

  public function connectconnect($host, $port = 80, $secure = false)
  { 
   ...
    // Replace the lines with socket connect
    $this->socket = stream_socket_client(
      $host . ':' . $port,
      $errno,
      $errstr,
      (float) $this->config['timeout'],
      $flags,
      $context
    );
    ...
    // Replace the lines with stream timeout
    // get the fraction of the float value and convert it microseconds
    $fraction = ($this->config['timeout'] - floor($this->config['timeout'])) * 1000;
    // Set the stream timeout               
    if (!stream_set_timeout($this->socket, (int) $this->config['timeout'], (int) $fraction)  {                                      
      throw new AdapterException\RuntimeException('Unable to set the connection timeout');
    }
    ...
  }
}

修补

文件

为要添加次秒超时的文件编写修补程序，并将其应用于ZendFramework 2版本。如果使用，您可以使用自动化流程。我创建了针对服务器的补丁

我不推荐这种方法，因为它有一些缺陷。
