craigslist rss feed [英] craigslist rss feed

问题描述

我正在尝试解析craigslist rss feed中的数据。

I'm trying to parse the data from a craigslist rss feed.

这是供稿网址 - http://www.craigslist.org/about/best/all/index.rss

This is the feed url - http://www.craigslist.org/about/best/all/index.rss

我正在使用jfeed而我的代码是如下所示

I'm using jfeed and my code is given below

jQuery(function() {

    jQuery.getFeed({
        url: 'proxy.php?url=http://www.craigslist.org/about/best/all/index.rss',
        success: function(feed) {        
            jQuery('#result').append('<h2>'
            + feed.title
            + '</h2>');                                

        }    
    });
});

但是，我没有显示Feed标题或Feed的任何其他属性。如果我只是尝试将输出打印到屏幕上，我会得到对象对象，这意味着它正确地返回了提要。

However, I don't get the feed title displayed or any other property of the feed. If i just try to print out the feed to the screen, I get 'Object Object' which means it correctly returned the feed.

有人知道我错过了什么吗？

Anybody know what I am missing?

推荐答案

首先：你无法从其他域获取数据，因为跨域策略。我不知道jfeed，但在我的项目中，我想出了这个解决方案。使用这个简单的功能，您可以节省一些带宽和代码开销。

First: You can't fetch data from another domain because the crossdomain policy. I don't know about jfeed but in my projects i came up with this Solution. With this simple function you can save some bandwidth and code overhead.

proxy.php (src: http://jquery-howto.blogspot.com/2009/04/cross-domain-ajax-querying-with-jquery.html)

<?php
// Set your return content type
header('Content-type: application/xml');

// Website url to open
$daurl = 'http://www.craigslist.org/about/best/all/index.rss';

// Get that website's content
$handle = fopen($daurl, "r");

// If there is something, read and return
if ($handle) {
    while (!feof($handle)) {
        $buffer = fgets($handle, 4096);
        echo $buffer;
    }
    fclose($handle);
}
?>

jQuery

$.ajax({
    type: "GET",
    url: "proxy.php",
    dataType: "xml",
    success: parseXml
 });

function parseXml(xml) {
    console.log(xml);
    $(xml).find("item").each(function() {
        var content = $(this).find("title").text()
        $("#news_list").append('<li>' + content +'</li>');
    });
}
