vue + webpack如何绕过QQ音乐接口对host的验证详解

function jsonp(url, data, options) {
 // 如果存在?则直接加params(data), 否则先加?再加 params(data)
 url += (url.indexOf('?') < 0 ? '?' : '') + params(data)
 // 结果返回一个Promise对象
 return new Promise((resolve, reject) => {
 originJSONP(url, options, (err, data) => {
  if (!err) {
  resolve(data)
  } else {
  reject(err)
  }
 })
 })
}

function params(data) {
 let params = ''
 for (var k in data) {
 let value = data[k] != undefined ? data[k] : ''
 // url += '&' + k + '=' + encodeURIComponent(value) ES5
 params += `&${k}=${encodeURIComponent(value)}` // ES6
 }
 // 去掉首个参数的&, 因为jsonp方法中参数自带&
 return params ? params.substring(1) : ''
}
