问题 I am trying to get a json file from my server. Until now, always I need a json file, it was got by ajax and a php file in server creates the json file. Not I have a json file (X.json) with this structure: { "zona": [ { "zona1": [ { "lon": "a", "lat": "b" }, { "lon": "aa", "lat": "bb" }, { "lon": "aaa", "lat": "bbb" }, { "lon": "aaaa", "lat": "bbbb" } ] }, { "zona2": [ { "lon": "c", "lat": "d" }, { "lon": "cc", "lat": "dd" }, { "lon": "ccc", "lat": "ddd" }, { "lon": "cccc", "lat": "dddd" }, {

Error retrieving jsonp from aurelia http client

问题 I have an application I am creating using Aurelia. I wish to retrieve the latest images from a user in instagram via ajax. I tried using the Aurelia http client because that's what the Flickr example on Aurelia's getting started page uses. If I use http.get , then I get a CORS error from instagram. Trying http.jsonp , the inspected response shows the correct format, but I get what looks like a parsing error (Unexpected token ":") before the callback that handles the response is being executed

解决ajax跨域几种方式

发生跨域问题的原因: 浏览器的限制,出于安全考虑。前台可以正常访问后台,浏览器多管闲事报跨域问题,但其实前台已经访问到后台了。 跨域,协议、域名、端口任何一个不一样浏览器就认为是跨域。 XHR(XMLHttpRequest)请求,因为ajax是XHR请求,浏览器就会捕捉跨域问题。 解决思路: 让浏览器不做限制,指定参数,让浏览器不做校验,但该方法不太合理,它需要每个人都去做改动。 不要发出XHR请求,这样就算是跨域,浏览器也不会报错,解决方案是JSONP,通过动态创建一个script,通过script发出请求。 在跨域的角度:一种是被调用方修改代码,加上字段,告诉浏览器,支持跨域,支持调用 通过nginx代理方式,在a域名里面的的请求地址使用代理指定到b域名。 跨域解决方案: 被调用方解决:在请求响应头增加指定字段,告诉浏览器允许调用。这种解决方案的请求是直接从浏览器发送的。( 服务器端实现、NGINX配置Apache配置) 调用方解决:这是隐藏跨域的解决法案。这种跨域请求不是直接从浏览器发送的,而是从中间的http服务器转发过去的。 设置浏览器不做限制: 可以使用everyting软件搜索浏览器的全路径,使用dos切换到此路径下 cd C:\Users\Administrator\AppData\Local\Google\Chrome\Application 输入 chrome

AngularJS resource service with jsonp fails

别来无恙 提交于 2019-12-07 23:56:17
问题 I'm trying to fetch the JSON output of a rest api in AngularJS. Here are the problems I'm facing: The Rest api url has the port number in it which is being interpolated by AngularJS for a variable. I tried several resolutions for this in vain. I'm having issues with JSONP method. Rest api isn't hosted on the same domain/server and hence a simple get isn't working. The parameters to the rest api are slash separated and not like a HTML query string. One of the parameters is an email address and

因为一个斜杠导致的莫名奇妙的JS报错

感情迁移 提交于 2019-12-07 20:26:04
今天加班了半个多小时,就因为一个斜杠,因为从别的页面传过来的数据里居然带着JS代码,其中有个地方写了script="text/javascript",于是就一直报错,对比其他页面,基本上都是相同的,为啥这里就出错呢,因为我们这个系统在json数据里包含里JS,结果这个斜杠没转义成功,于是就悲剧了。姑且记下。 更正一下,不是json是jsonp 今天总算搞清楚了,jsonp不就是动态插入script嘛 来源: oschina 链接: https://my.oschina.net/u/131224/blog/33449

using jquery + jsonp, Internet explorer isn't saving the ASP.NET sessionID

左心房为你撑大大i 提交于 2019-12-07 19:49:38
问题 So I am doing some fairly simple JSONP stuff using Jquery. General structure Site lives on domain A Javascript lives on domain B JSON services also live on domain B The site calls a method which jsonp calls out to a json service (.net) , in .net i set the session and return. This all works fine, except in IE it is not storing or passing the session id in subsequent requests.. So .net creates a new one every time. If i go to the JSON url directly, ie happily stores it, and will use it on
