我的实战案例:
我用的语言是Node.js,Ajax本来在项目中是不能跨域访问的，我就自定义了一个Ajax
当然，在Node.js中也可以用http，但是我的这段代码在沙箱运行，所以只能用自定义的Ajax请求获取外部数据
function getCityWeather(citynum){
//var http = require('http');
var options = {
host: 'www.weather.com.cn',
path: '/data/cityinfo/'+citynum+'.html',
method: 'GET'
};
var req = api.ajax.get(options, function(res) {
var pageData = "";
res.setEncoding('UTF-8');
res.on('data', function (chunk) {
pageData += chunk;
});
res.on('end', function(){
// console.log(pageData);
reply.text.content = "";
var obj = JSON.parse(pageData).weatherinfo;
var content = "城市:"+obj.city+"\n温度:"+obj.temp1+" - "+obj.temp2+"\n天气:"+obj.weather+"\n更新时间:"+obj.ptime;
responseEnd(content);
});
});
}
如有错误，希望大家指点指点...coolspan
