用dedecms的下载类 远程下载图片到本地失败 局域网内的图片可以下载成功 外网的图片无法下载?
如果把$url改为外网地址,就没有任何反应
完整的代码如下——http://my.csdn.net/my/code/detail/27411 可直接复制代码

<?php

$revalues = array( );
$ok = false;

$htd = new dedehttpdown( );



$htd->openurl( $url );

return "";

}

$revalues[0] = $rndtrueName;
list( , $revalues[2], $revalues[2] ) = $data;
}
$htd->close( );

}
return "";
}

省略掉dede的代码,详细链接http://my.csdn.net/my/code/detail/27411

服务器配置信息问题,假如你用的是phpnow appsrv xmapp wmapp= 请你安装位纯净版的php运行环境,已经测试过,可以通过。

不知道你改动了多少地方 按#13的用 $this->m_fp = @stream_socket_client($this->m_host . ':' . $this->m_port, $errno, $errstr, 10); 即可获取远程图片

上面发错了 这句才是原来的 $this->m_fp = @fsockopen($this->m_host, $this->m_port, $errno, $errstr,10);

$this->m_fp = @stream_socket_client($this->m_host.$this->m_port, $errno, $errstr, 10); 是原来的

function make_dir( $folder ) { $reval = false; if ( !file_exists( $folder ) ) { @umask( 0 ); preg_match_all( "/([^\\/]*)\\/?/i", $folder, $atmp ); 应写作 preg_match_all( "/([^\/]*)\/?/i", $folder, $atmp ); 或 preg_match_all( "#([^/]*)/?#i", $folder, $atmp );

先问一下 function PrivateOpenHost() { if($this->m_host=="") { return FALSE; } $errno = ""; $errstr = ""; // stream_socket_client //$this->m_fp = @pfsockopen($this->m_host, $this->m_port, $errno, $errstr,10); $this->m_fp = @stream_socket_client($this->m_host.$this->m_port, $errno, $errstr, 10); 这两句那个是原来的? $this->m_fp = @stream_socket_client($this->m_host.$this->m_port, $errno, $errstr, 10); 应该为 $this->m_fp = @stream_socket_client($this->m_host . ':' . $this->m_port, $errno, $errstr, 10); 这样就可以了。只是你创建目录的部分没有执行,或有错 如果 $this->m_fp = @pfsockopen($this->m_host, $this->m_port, $errno, $errstr,10); 是原来的 那么在 //获取应答头状态信息 $httpstas = explode(" ",fgets($this->m_fp,256)); $this->m_httphead["http-edition"] = trim($httpstas[0]); $this->m_httphead["http-state"] = trim($httpstas[1]); 有错,原因待查

代码如上,两部分组成 ,有人说是 fsockopen的问题,我打开禁用和使用pfsockopen任然无法解决问题。
