Is it possible to make a JSONP request from HTTPS to HTTP?

问题 I know there is an almost duplicate question, but the answer is not satisfactory at all. I need to do geocoding using the Openstreetmap service which runs over HTTP. My site runs over HTTPS. It seems impossible to do JSONP request from https to http, browser (Chrome) complains about insecure content. Any solutions? 回答1: The reason that the browser complains about insecure content is that the content is insecure. The entire purpose with a secure page is that all of it is secure, and can be

Is there a way to enable CORS on Github pages?

问题 I'm hosting some JSON files on Github pages, but I am unable to use $.getJSON to retrieve them unless they come from the exact same domain. Is there a way to enable CORS for Github pages? 回答1: As a workaround one can use JSONP, but it's still slightly a pain because the files are static, and each one will need a unique callback method. Another alternative would be to store the files in Gists and use the Github API which works with CORS. A third possibility is to not store the files on Github

Jquery jsonp response error - Callback was not called

由 给你一囗甜甜゛ 提交于 2020-01-01 03:28:04
问题 I'm trying to get some information from a different domain, the domain allows only jsonp call - others get rejected. How can I get the content instead of execution? Because I get an error in response. I don't need to execute it, I just need it in my script. In any format (the response is json but js doesn't understand it). I can't affect on that domain so it's impossible to change something on that side. Here's my code: $.ajax({ url: url + '?callback=?', crossDomain: true, type: "POST", data:

ajax 跨域请求

一、使用ajax进行跨域请求是会出现错误： Access to XMLHttpRequest at 'http://www.smarthui.top/memo/major.json' from origin 'http://localhost:8080' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. 二、解决方案： (1) 在ajax中 dataType: "jsonp",//预期服务器返回的数据类型 datatype设置为jsonp。 JSON和JSONP虽然只有一个字母的差别，但其实他们根本不是一回事儿：JSON是一种数据交换格式，而JSONP是一种依靠开发人员的聪明才智创造出的一种非官方跨域数据交互协议。我们拿最近比较火的谍战片来打个比方，JSON是地下党们用来书写和交换情报的“暗号”，而JSONP则是把用暗号书写的情报传递给自己同志时使用的接头方式。 一个是描述信息的格式，一个是信息传递双方约定的方式。 为了便于客户端使用数据，逐渐形成了一种非正式传输协议

Where is the correct place to enable CORS?

问题 I'm using Spyne (the example "hello world" code) to make a webservice that produces some json data and then I'm trying to consume this data in javascript code in client's browser. When I go to the address http://localhost:8000/say_hello?name=Dave&times=3 I get the following output: ["Hello, Dave", "Hello, Dave", "Hello, Dave"] That's why I think there is nothing to do with the server (it works as expected). I use the following code to get the data from this webservice: <html> <head> <meta

Uncaught SyntaxError and CORS error using AJAX with JSONP

问题 When I execute an AJAX call, I get following error: Uncaught SyntaxError: Unexpected token : However, when I access the same URL directly in my browser, I get the expecting JSON response. What am I doing wrong and how can I fix it? Below is my jQuery AJAX request; $.ajax({ type: 'GET', url: "http://www.exampleUrl.com", crossDomain: true, dataType: "jsonp", jsonp: "jsonp", mimeType: "application/json", jsonpCallback: 'callback', contentType: "application/json; charset=utf-8", beforeSend:

How to reliably secure public JSONP requests?

由 喜你入骨 提交于 2019-12-31 01:33:51
问题 I'm trying to find if there's a good way to prevent CSRF on a javascript widget embedded on customers' websites. The widget would enable end users to make requests against our customers' accounts via JSONP to a a PHP server which proxies those requests to our (non-public) API. To this point, I haven't come up with a surefire way to ensure all requests are coming from only our customers' websites. Some ideas I've had: Tokens generated on the server side and passed back along with each

get和post方式请求数据，jsonp

get方式请求数据： /*--> */ /*--> */ 　　　var theurl = "http://c.m.163.com/nc/article/headline/T1348647853363/0-140.html" ; myUrl = encodeURIComponent(theurl); url = "http://127.0.0.1:3000?myUrl=" + myUrl; $http({ url : url, method : "get" }). then (function ( res ) { console.log(res); }, function( err) { console.log(err); }); 通过jsonp请求数据，通过动态创建script标签来访问服务器，把回调函数名作为参数传递给服务器 服务器请求得到数据以后,把数据放回到回调函数中 前端通过回调函数的实现部分,得到数据。 /*--> */ /*--> */ var script = document.createElement( "script"); url = url + "&callback=xxx" ; script.src = url; document.documentElement.appendChild(script); angular的$http服务中

SSM(六)跨域传输

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 前言 不知大家在平时的开发过程中有没有遇到过跨域访问资源的问题，我不巧在上周就碰到一个这样的问题，幸运的是在公司前端同学的帮忙下解决了该问题。 什么是跨域问题？ 只要协议、域名、端口有任何一个不同，都被当作是不同的域 只要是在不同域中是无法进行通信的。 基于以上的的出发点，我们又有跨域共享资源的需求( 譬如现在流行的前后端分离之后分别部署的情况 )，本文所采用的解决办法是 JSONP ，说到 JSONP 就会首先想到 JSON 。虽然只有一字之差但意义却完全不一样，首先科普一下 JSON 。 JSON 其实现在 JSON 已经是相当流行了，只要涉及到前后端的数据交互大都都是采用的JSON(不管是web还是android和IOS)，所以我这里就举一个例子，就算是没有用过的同学也能很快明白其中的意思。 PostMan 首先给大家安利一款后端开发的利器 PostMan ,可以用于模拟几乎所有的 HTTP 请求，在开发阶段调试后端接口非常有用。 这是一个Chrome插件，可以直接在google商店搜索直接下载(当然前提你懂得)。 之后界面就如下： 。 界面非常简洁，有点开发经验的童鞋应该都会使用，不太会用的直接google下就可以了比较简单。 接着我们就可以利用 PostMan 来发起一次请求获取 JSON 了
