使Sphider输出JSON [英] Getting Sphider to output JSON

问题描述

我最近在我的网站上添加了 Sphider 搜寻器，以添加搜索功能.但是我下载的Sphider发行版附带的默认search.php太简单了，无法与我网站的其余部分很好地集成.我在网站顶部有一个小的导航栏，其中有一个搜索框，我希望能够使用Ajax通过该搜索字段访问Sphider的搜索结果.为此，我认为我需要让Sphider以JSON格式返回其结果.

I've recently added the Sphider crawler to my site in order to add search functionality. But the default search.php that comes with the distribution of Sphider that I downloaded is too plain and doesn't integrate well with the rest of my site. I have a little navigation bar at the top of the site which has a search box in it, and I'd like to be able to access Sphider's search results through that search field using Ajax. To do this, I figure I need to get Sphider to return its results in JSON format.

我这样做的方式是我使用了一个输出JSON的主题"(Sphider支持其输出主题化").我在Sphider网站上的此线程上找到了该主题.它似乎可以正常工作，但是更严格的JSON解析器不会解析它.这是一些JSON输出示例:

The way I did that is I used a "theme" that outputs JSON (Sphider supposts "theming" its output). I found that theme on this thread on Sphider's site. It seems to work, but more strict JSON parsers will not parse it. Here's some example JSON output:

{"result_report":"Displaying results 1 - 1 of 1 match (0 seconds) ", "results":[ { "idented":"false", "num":"1", "weight":"[100.00%]", "link":"http://www.avtainsys.com/articles/Triple_Contraints", "title":"Triple Contraints", "description":" on 01/06/12 Project triple constraints are time, cost, and quality. These are the three constraints that control the performance of the project. Think about this triple-constraint as a three-leg tripod. If one of the legs is elongated or", "link2":"http://www.avtainsys.com/articles/Triple_Contraints", "size":"3.3kb" }, { "num":"-1" } ], "other_pages":[ { "title":"1", "link":"search.php?query=constraints&start=1&search=1&results=10&type=and&domain=", "active":"true" }, ] }

问题在于末尾有逗号结尾.根据此，使用PHP的json_decode()功能.此JSON也无法使用此在线格式化程序进行解析.但是当我取出逗号时，它起作用了，我得到了格式更好的JSON:

The issue is that there is a trailing comma near the end. According to this, "trailing commas are not allowed" when using PHP's json_decode() function. This JSON also failed to parse using this online formatter. But when I took the comma out, it worked and I got this better-formatted JSON:

{
   "result_report":"Displaying results 1 - 1 of 1 match (0 seconds) ",
   "results":[
      {
         "idented":"false",
         "num":"1",
         "weight":"[100.00%]",
         "link":"http://www.avtainsys.com/articles/Triple_Contraints",
         "title":"Triple Contraints",
         "description":" on 01/06/12 Project triple constraints are time, cost, and quality. These are the three constraints that control the performance of the project. Think about this triple-constraint as a three-leg tripod. If one of the legs is elongated or",
         "link2":"http://www.avtainsys.com/articles/Triple_Contraints",
         "size":"3.3kb"
      },
      {
         "num":"-1"
      }
   ],
   "other_pages":[
      {
         "title":"1",
         "link":"search.php?query=constraints&start=1&search=1&results=10&type=and&domain=",
         "active":"true"
      }
   ]
}

现在，我将如何以编程方式执行此操作?并且(也许更重要的是)，是否有更优雅的方式来实现这一目标?而且您应该知道，PHP是我可以在共享主机帐户上运行的唯一语言，因此，例如Java解决方案对我不起作用.

Now, how would I do this programmatically? And (perhaps more importantly), is there a more elegant way of accomplishing this? And you should know that PHP is the only language I can run on my shared hosting account, so a Java solution for example would not work for me.

推荐答案

在search_result.html中，可以将forc循环末尾的,包围起来，条件是仅在索引严格小于数字时才打印页数-1.

In search_result.html, you can surround the , at the end of the foreach loop with condition to only print if the index is strictly less than the number of pages - 1.
