jsonp

问题 I am trying to use the OpenWeatherAPI to perform get JSONP data using a JQuery get request. I have structured my query like this: function getWeather(callback) { var weather = 'http://openweathermap.org/data/2.1/find/city?lat=13.3428&lon=-6.2661&cnt=10&jsoncallback=?'; jQuery.getJSON(weather, callback); } // get data: getWeather(function(data){ console.log('weather data received'); }); I get the following error message: SyntaxError: invalid label However, the data is being returned as I can

问题 I am trying to query the http://developer.pintlabs.com/brewerydb/api-documentation with jquery.ajax. These are two of the Jquery requests i tried (note that "O3tmVI" is a dummy ID): $.ajax({ url:"http://api.playground.brewerydb.com/beer/" + "O3tmVI" + "?key=A1029384756B&format=json", dataType: "jsonp", jsonpCallback: "callbackfunctie", success:function(oData){ var returnData = oData; console.log(returnData); } }); And: $.getJSON("http://api.playground.brewerydb.com/beer/" + "O3tmVI" + "?key

问题 I'm trying to fetch a bunch of photo data from Flickr via a jQuery AJAX call using JSONP, but I don't want to use the data right away. Instead, I'd like to preserve it for use later. In a complicated case, I'd like to let users perform different queries on the prefetched data. In a simpler case, I'd like to just load the next n images each time the user clicks a button. Right now, I'm testing just the most basic functionality below, which is adapted from the best answer to this question:

问题 Can someone show an example of an HTTP Handler that returns JSON and supports cross domain calls. I am using jQuery's getJSON() that sends a request to an .ashx file on my web server. I understand that I need to add ?callback=? to my url in the getJSON() url, but I'm not sure what needs to be done on the server in my ashx file? 回答1: Figured it out. I added this function to my handler and called it: void WriteCallback(HttpContext context, string json) { context.Response.Write(string.Format("{0

问题 I'm trying to learn AngularJS by making a simple web app using the Twitch API (https://github.com/justintv/Twitch-API) but I'm having trouble performing a GET request since it's a cross-domain request. This is what I have tried angular.module('streamPlaylisterAppServices', []).factory('twitchService', ['$http', function($http) { return function(usercode){ console.log("usercode inside service is: " + usercode) var authHeader = 'OAuth' + usercode; return $http({ method: 'GET', url: ' https:/

问题 Does anyone know how I might get the headers from the response of a jsonp request? The docs don't mention specifically that this isn't supported, but getReponseHeader always returns null for the header I'm interested in. Is it not possible to get the headers for a request when the response is a script? Google Chrome shows the header coming back with the response, but I just can't grab it from the jqXHR object. 回答1: No, unfortunately not: given that the request is executed using a <script> tag

问题 I don't see how the callback function in JSONP is any different from the success callback function in AJAX. Given #1, I don't see how it is fundamentally more secure. So is the only difference an artificial same-domain constraint with AJAX? Why can't AJAX just allow cross-domain requests; if this can cause a security hole, wouldn't the attack just XSS a JSONP request? Confused, Max 回答1: An ajax call is an actual HTTP request from your client directly to a server. Ajax calls can be synchronous

问题 As its Javadocs suggest, the JsonpRequestBuilder can only send GET requests. I need to send POST requests using the same method (for cross domain requests using JSON). Does anybody know any working solution? I could not find any starting point on the web. thanks in advance 回答1: You can't use JSONP to do a POST - all it does is inserting a <script src="..."> tag, and the browser fires off a GET request. Maybe what you're looking for is CORS, but that's only supported by FF 3.5, IE 8 and Safari

问题 Im trying to solve this problem for hours now. I got a wikia web which I want to get stuff from but it supports only json, not even xml or jsonp. I tried everything. If I call it as jsonp my client returns error "SyntaxError: invalid label" cause the server doesnt return it as jsonp or json at all. If I add "callback=?" to the url and leave it as json, same error returned. Here is part of my code (I modified it too many times and nothing worked so far) $('#searchBox').keydown(function() { $

问题 Now I'm working to do twitter client with Javascript. After I read this topic, I have question Modify HTTP Headers for a JSONP request He told impossible way to modify HTTP Header when using JSONP. If it's true. How does twitter extension work in Chrome ? I think Chrome extension use Javascript, too. 回答1: Extensions have more privileges then "normal" JavaScript code executing within a page.
