我们新配置了一台服务器但在使用dedecms系统时发现远程图片都无法本地化了,就是无法保存远程服务器图片到本地了,出现这种问题我想了可能几个原因,下面我们一起来看看解决办法.</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
原因分析:dedecms 远程图片本地化用到函数 fsockopen函数,所以我们要求空间相应目录可写外还要求php的allow_url_fopen 选项设置为On.</p>

修改PHP的配置文件,找到php.ini变更内容,php.ini 文件里:<br>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode7" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
"allow_url_fopen = On"</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
为了防止WEB变种攻击LINUX虚拟主机PHP 禁用allow_url_fopen功能,引用allow_url_fopen功能在客户站点里运行恶意程序.</p>

如果上面解决不了我们看看是不是upload_tmp_dir没开打开:</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
upload_tmp_dir = "C:/php/tmp"</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
此项没有设置,将upload_tmp_dir项前面的分号去掉,并在后面添加好路径,上传就OK了,给C:/php/tmp目录users读取权限即可解决问题,当然如果你没有服务器权限,那么我们只要在程序上进行操作了.</p>

具体修改地方是 /include/dedehttpdown.class.php 第507行,代码如下:<br>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode8" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
$this->m_fp = @fsockopen($this->m_host, $this->m_port, $errno, $errstr,10);</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
替换为:<br>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode9" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
$this->m_fp = @stream_socket_client($this->m_host . ':' . $this->m_port, $errno, $errstr,10);</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
保存之后试一下看看是不是可以了,当然如果服务器不能上外网也有可能不能下载远程图片到本地.</p>
