export default http
可以设置全局的url访问地址（会拼接请求的url成完整的url，所以在写url时只需要"/xxx"），也可以在请求时设置具体url（以http或https开头）
可以设置全局的header，如果请求时有header参数，会加上全局的header
可以设置拦截器，有发送请求前的拦截器beforeRequestFilter，参数是包含已经拼接完的url和header的请求参数，注意要返回；执行成功回调函数前的拦截器beforeResponseFilter，参数是回调成功函数的参数，注意要返回；执行成功回调函数后的拦截器afterResponseFilter，参数为成功回调函数的返回值。
具体例子
my.js
import http from './http'
const AUTH_TOKEN = "X-Auth-Token";
http.setBaseUrl("http://localhost:8081");
http.header['comp'] = "cjx913"
if (uni.getStorageSync(AUTH_TOKEN)) {
http.header[AUTH_TOKEN] = uni.getStorageSync(AUTH_TOKEN);
}
http.beforeResponseFilter = function (res) {
//X-Auth-Token
if (res.header) {
var respXAuthToken = res.header[AUTH_TOKEN.toLocaleLowerCase()];
if (respXAuthToken) {
uni.setStorageSync(AUTH_TOKEN, respXAuthToken);
http.header[AUTH_TOKEN] = respXAuthToken;
}
}
return res;
}
let my = {
'http': http
}
export default my
main.js
import Vue from 'vue'
import App from './App'
Vue.config.productionTip = true
App.mpType = 'app'
import fly from './fly/fly'
Vue.prototype.$fly = fly
import my from './my/my'
var http = my.http;
Vue.prototype.$http = http
import store from './store'
Vue.prototype.$store = store
const app = new Vue({
...App
})
app.$mount()
index.js
<script>
export default {
data() {
return {
title: 'Hello',
name:'cjx913'
}
},
onLoad() {
},
methods: {
session:function(){
// this.$fly.get('/session')
// .then(function (response) {
// console.log("hello");
// console.log(response.data);
// console.log(response);
// })
// .catch(function (error) {
// console.log(error);
// });
// this.$http.request({
// url:"session",
// success:(res)=>{
// console.log(res);
// }
// })
// this.$http.get("/session",function(res){
// console.log(res);
// }
// )
this.$http.get("/session",{
success:function(res){
console.log(res);
}
}
)
}
}
}
</script>
上述是简单设置baseUrl，header和通过拦截器拦截response的X-Auth-Token，并让请求带上X-Auth-Token
