Testing a static jsonp response

问题 I have no trouble making jsonp requests, however I'm unsure about setting up a web service to deliver responses in jsonp. First, does a server need to be configured in a certain way to allow jsonp requests, or does the page just have to have the response properly formatted? In my testing I have the following jsonp response from geonames.org (I've placed it a blank page on server/domain 1 with nothing else): <?php echo $_GET['callback'];?>({"postalcodes":[{"adminName2":"Westchester",

jsonp在java中的使用

jsonp的实现原理 由于浏览器同源策略的限制,非同源下的请求,都会产生跨域问题,jsonp即是为了解决这个问题出现的一种简便解决方案。 同源策略即:同一协议,同一域名,同一端口号。当其中一个不满足时,我们的请求即会发生跨域问题。 但是,细心的朋友可能会发现盗链这一现象就是在请求不属于自己的图片等资源,比如说你直接盗链百度的图片,你的应用肯定和百度的应用跨域了,那为什么可以加载到百度的图片呢?答案是不管是我们的script标签的src还是img标签的src,或者说link标签的href他们没有被通源策略所限制。 jsonp就是通过请求伪造的静态资源(实际是跨域的后台请求),将后台放回数据返回页面的。 jsonp的实现 后端返回 package test ; import java . io . IOException ; import javax . servlet . ServletException ; import javax . servlet . annotation . WebServlet ; import javax . servlet . http . HttpServlet ; import javax . servlet . http . HttpServletRequest ; import javax . servlet . http .

求超大文件上传方案( B/S )

需求:项目要支持大文件上传功能,经过讨论,初步将文件上传大小控制在500M内,因此自己需要在项目中进行文件上传部分的调整和配置,自己将大小都以501M来进行限制。 第一步: 前端修改 由于项目使用的是BJUI前端框架,并没有使用框架本身的文件上传控件,而使用的基于jQuery的Uploadify文件上传组件,在项目使用的jslib项目中找到了BJUI框架集成jQuery Uploadify的部分,这部分代码封装在bjui-all.js文件中, 在bjui-all.js文件中的全局变量定义中有以下部分代码,这就是定义的有关于上传的Uploadify控件的重要变量: //文件上传对象 function FileUploader(fileLoc, mgr) { var _this = this; this.id = fileLoc.id; this.ui = { msg: null, process: null, percent: null, btn: { del: null, cancel: null,post:null,stop:null }, div: null}; this.isFolder = false; //不是文件夹 this.app = mgr.app; this.Manager = mgr; //上传管理器指针 this.event = mgr.event; this

How can I use $.ajax to retrieve normal JSON as JSONP?

别说谁变了你拦得住时间么 提交于 2020-01-17 02:41:50
问题 I have a normal JSON feed that I am polling at a url (normalJSONfeed). I am getting the cross origin policy error each time. How can I alter the $.ajax function to get around this limitation when I do not have any way of changing the JSON feed (in other words I can not wrap the JSON feed in a function call). $.ajax({ type : "GET", dataType : "jsonp", url : '/normalJSONfeed', data : {} success: function(obj){ } }); 回答1: There is nothing that you can change in the code only that lets you
