通过Json跨域调用Twitter
之前用过这个方法,最近发现这方法好像不好使了,无法读出任何数据。当然,即使采用此方法,也需要保证你的域处于墙外,否则肯定不好使。
1. twitter_json.php API接口文件
<?php
$call=trim(urlencode($_REQUEST['callback']));
$user=trim(urlencode($_REQUEST['username']));
$count=trim(urlencode($_REQUEST['count']));
//echo $call.'('.file_get_contents('https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name='.$user.'&count='.$count).')';
echo $call.'('.file_get_contents('https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name='.$user.'&count='.$count).')';
?>
2. get_twitter.js 处理接收数据的JS文件
//用来处理twitter API 返回的JSON数据
function getTwitter(twitters) {
var statusHTML = [];
for (var i=0; i<twitters.length; i++){
var username = twitters[i].user.screen_name;
var status = twitters[i].text.replace(/((https?|s?ftp|ssh)\:\/\/[^"\s\<\>]*[^.,;'">\:\s\<\>\)\]\!])/g, function(url) {
return '<a href="'+url+'">'+url+'</a>';
}).replace(/\B@([_a-z0-9]+)/ig, function(reply) {
return reply.charAt(0)+'<a href="http://twitter.com/'+reply.substring(1)+'">'+reply.substring(1)+'</a>';
});
if (i%2==0){
statusHTML.push('<li class="tweet odd">'+status+'<span class="time">'+relative_time(twitters[i].created_at)+'</span></li>');
} else{
statusHTML.push('<li class="tweet even">'+status+'<span class="time">'+relative_time(twitters[i].created_at)+'</span></li>');
}
}
//if (statusHTML == ''){statusHTML.push('<li>Following me On Twitter...</li>')}
document.getElementById('twitter-loading').style.display="none";
document.getElementById('twitter-list').innerHTML = statusHTML.join('');
}
//处理日期
function relative_time(time_value) {
var values = time_value.split(" ");
time_value = values[1] + " " + values[2] + ", " + values[5] + " " + values[3];
var parsed_date = Date.parse(time_value);
var relative_to = (arguments.length > 1) ? arguments[1] : new Date();
var delta = parseInt((relative_to.getTime() - parsed_date) / 1000);
delta = delta + (relative_to.getTimezoneOffset() * 60);
if (delta < 60) {
return 'now';
} else if(delta < 120) {
return '1 minute ago';
} else if(delta < (60*60)) {
return (parseInt(delta / 60)).toString() + ' minutes ago';
} else if(delta < (120*60)) {
return '1 hour ago';
} else if(delta < (24*60*60)) {
return + (parseInt(delta / 3600)).toString() + ' hours ago';
} else if(delta < (48*60*60)) {
return '1 day ago';
} else {
return (parseInt(delta / 86400)).toString() + ' days ago';
}
}
3. 终端页调用
