[dcloudio/mui]$.getJSON(url, data, success) 返回 406

在chrome中截图一下response的详情

初步判定是mui的原生方式不支持jsonp

嗯。目前支持json数据请求，但暂未支持jsonp请求。

参考一下jquery，flyjsonp之类的，代码非常少，移动开发没有jsonp怎么混啊

(function() { var JSONP, computedUrl, createElement, encode, noop, objectToURI, random, randomString;

createElement = function(tag) { return window.document.createElement(tag); };

encode = window.encodeURIComponent;

random = Math.random;

JSONP = function(options) { var callback, done, head, params, script; options = options ? options : {}; params = { data: options.data || {}, error: options.error || noop, success: options.success || noop, beforeSend: options.beforeSend || noop, complete: options.complete || noop, url: options.url || '' }; params.computedUrl = computedUrl(params); if (params.url.length === 0) { throw new Error('MissingUrl'); } done = false; if (params.beforeSend({}, params) !== false) { callback = params.data[options.callbackName || 'callback'] = 'jsonp_' + randomString(15); window[callback] = function(data) { params.success(data, params); params.complete(data, params); try { return delete window[callback]; } catch (_error) { window[callback] = void 0; return void 0; } }; script = createElement('script'); script.src = computedUrl(params); script.async = true; script.onerror = function(evt) { params.error({ url: script.src, event: evt }); return params.complete({ url: script.src, event: evt }, params); }; script.onload = script.onreadystatechange = function() { if (!done && (!this.readyState || this.readyState === 'loaded' || this.readyState === 'complete')) { done = true; script.onload = script.onreadystatechange = null; if (script && script.parentNode) { script.parentNode.removeChild(script); } return script = null; } }; head = head || window.document.getElementsByTagName('head')[0] || window.document.documentElement; return head.insertBefore(script, head.firstChild); } };

noop = function() { return void 0; };

computedUrl = function(params) { var url; url = params.url; url += params.url.indexOf('?') < 0 ? '?' : '&'; url += objectToURI(params.data); return url; };

randomString = function(length) { var str; str = ''; while (str.length < length) { str += random().toString(36)[2]; } return str; };

objectToURI = function(obj) { var data, key, value; data = []; for (key in obj) { value = obj[key]; data.push(encode(key) + '=' + encode(value)); } return data.join('&'); };

if ((typeof define !== "undefined" && define !== null) && define.amd) { define(function() { return JSONP; }); } else if ((typeof module !== "undefined" && module !== null) && module.exports) { module.exports = JSONP; } else { this.JSONP = JSONP; }

}).call(this);

jsonp主要是解决跨域问题。目前在5+app里，不存在这个问题。所以暂时没有提供。后续会实现一下jsonp的支持
