一、安装jsonp
"dependencies": {
"vue": "^2.3.3",
"vue-router": "^2.5.3",
"vuex": "^2.3.1",
"fastclick": "^1.0.6",
"vue-lazyload": "1.0.3",
"axios": "^0.16.1",
"jsonp": "0.2.1"
}, 二、封装
import originJsonp
from 'jsonp'
// 封装一个JSONP
export default function jsonp(url, data, option) {
url
+= (url.
indexOf(
'?')
< 0 ? '?' : '&')
+ param(data)
return new Promise((resolve, reject)
=> {
originJsonp(url, option, (err, data)
=> {
if (
!err) {
resolve(data)
}
else {
reject(err)
}
})
})
}
export function param(data) {
let url = ''
for (
var k in data) {
let value = data[
k]
!== undefined ? data[
k]
: ''
url += '&' + k + '=' + encodeURIComponent(
value)
}
return url ? url.
substring(
1)
: ''
}
