Vue簡單封裝axios之解決post請求後端接收不到引數問題

1.在src/下新建api資料夾,api/下新建index.js和public.js

在public.js中:

import axios from 'axios';
import qs from 'qs'
import router from '../router'
import { MessageBox} from 'mint-ui'
// 注意點,按照以下寫
var instance = axios.create();
instance.defaults.timeout = 10000;
instance.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
export default {
  fetchGet(url,params = {}) {
    return new Promise((resolve,reject) => {
      axios.get(url,params).then(res => {
        if(res.data.code === 302) {
          MessageBox('提示','登入失效,請重新登入');
          MessageBox.alert('登入失效,請重新登入','提示').then(action => {  
            router.push("/login");
          });
        }
        resolve(res.data);
      }).catch(error => {
        reject(error);
      })
    })
  },fetchPost(url,params = {}) {
    /* 
    axios post請求後端接收不到引數問題:
    解決方案一:有效,但是相容性不是很好,不是所有瀏覽器都支援
      let data = new URLSearchParams()
      for (var key in params) {
        data.append(key,params[key])
      }
    */
    // 解決方案二:使用qs模組(axios中自帶),使用qs.stringify()序列化params
    return new Promise((resolve,reject) => {
      axios.post(url,qs.stringify(params)).then(res => {
        resolve(res.data);
      }).catch(error => {
        reject(error);
      })
    })
  }
}

2.在index.js中:

import http from './public'
export const getStation = (params) => {
  return http.fetchGet('/hydro/rest/getBelongUser',params);
}
export const userLogin = (params) => {
  return http.fetchPost("/hydro/rest/login",params);
}

3.在Login.vue中呼叫post請求方法:

<template>
  <div class="login">
    <h1>登入頁面</h1>
    <input type="text" placeholder="請輸入使用者名稱" v-model="Username">
    <input type="password" placeholder="請輸入密碼" v-model="Password">
    <input type="button" value="登入" @click="toLogin">
  </div>
</template>
<script>
import {userLogin} from "../../api/index"
export default {
 name: 'app',data() {
  return {
   Username: "",Password: ""
  }
 },methods: {
  toLogin() {
    let params = {
      username: this.Username,password: this.Password
    };
    userLogin(params).then(res => {
      if(res.code === 200) {
        this.$router.push("/home")
      }
    })
  }
 }
}
</script>

#### 4.在Home.vue呼叫get請求方法

<template>
  <h1 class="home">
    {{stationName}}
  </h1>
</template>
<script>
import {getStation} from "../../api/index"
export default {
  data() {
    return{
      stationName: ""
    }
  },created() {
    getStation().then(res => {
      this.stationName = res.msg;
    })
  }
}
</script>
