织梦采集,一般用不到采集网址有端口的情况,少数有端口的网址就无法采集了。总结了下dede无法采集端口不为80的网址错误解决:

  问题描述,当采集的网址后代端口时(为防止有推广嫌疑就把网址换成xxx了。):

  测试采集网址:http://www.xxx.com:89/index.php/main/news/index.html?channel_id=104&page=1

  获取的列表测试信息网址是不带端口的结果是不带端口的数组集合:

  测试的列表网址: http://www.xxx.com:89/index.php/main/news/index.html?channel_id=104&page=1

Array

  这样显然得到的网址是错误的。根本无法访问,也就无法采集了。

  经过一番查找,原来是dede 设置HTML的内容和来源网址 的函数问题,漏写端口判断了。

  在include/dedehtml2.class.php

  function SetSource 函数里大概79行加上红框里的内容:

  再测试一下。ok 了,这样网址就可以正常打开,采集到了。

  付上代码:

function SetSource(&$html, $url = '', $linktype='')
  {
  $this->__construct();
  $this->CAtt = new DedeAttribute2();
  $url = trim($url);
  $this->SourceHtml = $html;
  $this->BaseUrl = $url;
  //判断文档相对于当前的路径
  $urls = @parse_url($url);
  $port=$urls['port']=='80'?'':':'.$urls['port'];//lyy 为80时候可以省略,否则就加上
  $this->HomeUrl = $urls['host'].$port;
  $this->BaseUrlPath = $this->HomeUrl.$urls['path'];
  $this->BaseUrlPath = preg_replace("/\/([^\/]*)\.(.*)$/","/",$this->BaseUrlPath);
  $this->BaseUrlPath = preg_replace("/\/$/",'',$this->BaseUrlPath);
  if($linktype!='')
  {
  $this->GetLinkType = $linktype;
  }
  if($html != '')
  {
  $this->Analyser();
  }
  }
