基础axios用法请看axios官网
{
let instance = axios.create({
baseURL: process.env.BASE_API,timeout: 2000,headers: {
// "tracecode": window.encodeURIComponent(JSON.stringify({"ua":"","cv":"20161230","token":"3dwo0onUUsPKVJcP8tk","os":"windows10","app":"kind","ws":"1*1","pkey":"f8caf7d7-a5d4-4710-b06f-28a922b6a467"}))
"tracecode": commonBizHeader(isManager(options)),'Content-Type': 'application/x-www-form-urlencoded'
},transformRequest: [function (data) {
// Do whatever you want to transform the data
let ret = ''
for (let it in data) {
ret += encodeURIComponent(it) + '=' + encodeURIComponent(data[it]) + '&'
}
return ret
}]
});
instance.interceptors.request.use(function (response) {
// 请求拦截
loading();
return response;
},function (error) {
console.log('error 请求拦截 : ',error)
return Promise.reject(error);
});
instance(options)
.then(response => {
const res = response.data;
if (res.errorCode != status.SUCCESS) {
switch (res.errorCode) {
case status.NET_ERR: {
errorPrompt(res.errorMsg)
reject(res)
break;
}
case status.BIZ_ERR: {
errorPrompt(res.errorMsg)
reject(res)
break;
}
case status.NO_AUTH: {
errorPrompt(res.errorMsg)
let session = require("storejs")
if (isManager(options)) { // 管理端
session.remove("managerUserToken")
router.push({path: '/manager/login'})
} else {
session.remove("clientUserToken")
router.push({path: '/client/login'})
}
reject(res)
break
}
}
}
closeLoading();
resolve(res);
}).catch(error => {
closeLoading();
errorPrompt('网络连接错误，请检查您的网络')
console.log('error',error); // for debug
reject(error);
});
});
}
function commonBizHeader (isManager) {
let session = require("storejs");
let params = {}
params['ua'] = window.navigator.userAgent.toLowerCase()
params['cv'] = '123456'
params['ws'] = window.screen.height + '*' + window.screen.width
params['token'] = "123456"
params['os'] = window.navigator.appCodeName
if (isManager) {
params['token'] = session.get('managerUserToken') // 管理 - 用户令牌
} else {
params['token'] = session.get('clientUserToken') // 用户 - 用户令牌
}
params['app'] = 'kind'
let UUID = session.get('pkey')
if (!UUID) {
UUID = getUUID()
window.localStorage.setItem('pkey',UUID)
}
return encodeURIComponent(JSON.stringify(params))
}
function isManager(options) {
return options && options.url && options.url.indexOf("/api/worker") != -1
}
/**
* 获取UUID
* @returns {string}
*/
export function getUUID() {
let len = 32 // 32长度
let radix = 16 // 16进制
let chars = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'.split('')
let uuid = []
let i
radix = radix || chars.length
if (len) {
for (i = 0; i < len; i++) {
uuid[i] = chars[0 | Math.random() * radix]
}
} else {
var r
uuid[8] = uuid[13] = uuid[18] = uuid[23] = '-'
uuid[14] = '4'
for (i = 0; i < 36; i++) {
if (!uuid[i]) {
r = 0 | Math.random() * 16
uuid[i] = chars[(i === 19) ? (r & 0x3) | 0x8 : r]
}
}
}
return uuid.join('').toLowerCase()
}
这是在vue的项目中：在api中调用方法如下(react刚开始学，还在做简单demo)
{
return fetch({
url: '/api/auth/code',method: 'post',data: ({
userPhone: userPhone,}),})
}
因为我们这边的后台要求严格区分get/post请求，所以封装的方法调用中必须带有method,如后台已经处理好，全部可进行post请求，则可以参照axios官网里面将方法全部改为.post
关于fetch方法的说明：主要进行封装了请求拦截，响应拦截，默认请求体由json格式转换form格式，当然，这些都是在axios官网里可以找到的，不过是集合下了而已
关于请求头部分请不要直接套用，这是我们这边后台要求特殊配置的，后台接口三端共用，必须区分是哪里在调用
以上这篇基于axios封装fetch方法及调用实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持编程之家。
