1.安装fetch: npm install whatwg-fetch --save
2.在入口index.js文件中引入 import 'whatwg-fetch'
3.let url = global.commonIP + '/api/users/login'
let _this = this
fetch(url, {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
loginName: 'yj',
password: 'yj',
})
}).then(function(res){
res.json().then(function(obj){
if(obj.errcode == '200'){
alert('登录成功')
_this.$router.push('/')
}
})
})
4.上传文件
let url = global.commonIP + 'api/uploadFile/upload'
let _this = this
let data = new FormData()
data.append('uploadFile', this.$refs.file.files[0])
data.append('type', '2')
fetch(url, {
method: 'POST',
body: data
}).then(function(res){
res.json().then(function(obj){
switch(obj.errcode){
case '200':
alert('上传成功')
break;
default:
alert(obj.errmsg)
}
})
})
5.跨域
fetch(url, {
method: 'GET',
mode: "cors",
headers: {
'Accept':'application/json,text/plain,/'
}
}).then(function(res){
console.log(res.text())
})

6.兼容问题需要安装es6-promise解决
![](https://img.haomeiwen.com/i6549705/fb49a76d36cc787e.png)
在main.js文件:
import promise from 'es6-promise'
promise.polyfill();
