jQuery和CORS [英] jQuery and CORS
问题描述
我应该如何处理这个如果服务器不与JSONP响应?我试过几个选项与$阿贾克斯,但不能让它的工作。
// VAR URL ='https://coinbase.com/api/v1/currencies/exchange_rates';
VAR URL ='http://blockchain.info/ticker';
$阿贾克斯({
键入:GET,
网址:网址,
// jsonpCallback:jsonCallback,
的contentType:应用/ JSON的,
//异步:假的,
//数据类型:JSONP,
// xhrFields:{
//为CORS?
// withCredentials:假的
//},
成功:函数(JSON){
调试器;
},
错误:函数(JSON){
调试器;
}
});
它看起来像你试图发送一个Ajax请求blockchain.info和检索的JSON提要。幸运的是,他们已经增加了支持CORS。
只要参数 CORS = TRUE
传递到请求的URL(例如, http://blockchain.info/ticker?cors=true
),你应该能够获取数据。
看起来CORS只支持少数API调用按<一个href="https://blockchain.info/api/blockchain_api">https://blockchain.info/api/blockchain_api.
How should I approach this if the server doesn't respond with JSONP? I've tried several options with $.ajax, but can't get it to work.
//var url = 'https://coinbase.com/api/v1/currencies/exchange_rates';
var url = 'http://blockchain.info/ticker';
$.ajax({
type: 'GET',
url: url,
//jsonpCallback: 'jsonCallback',
contentType: 'application/json',
//async: false,
//dataType: 'jsonp',
//xhrFields: {
// for CORS?
// withCredentials: false
//},
success: function (json) {
debugger;
},
error: function (json) {
debugger;
}
});
It looks like you're trying to send an AJAX request to blockchain.info and retrieve the JSON feed. Luckily they've added support for CORS.
Simply pass the parameter cors=true
to the requested url (ex. http://blockchain.info/ticker?cors=true
) and you should be able to grab the data.
Looks like CORS are only supported for a few API calls as per https://blockchain.info/api/blockchain_api.
