Detailed explanation of VueJs building Axios interface request tool example
In this article, we mainly introduce to you VueJs to build the Axios interface request tool. axios is an HTTP client based on Promise for browsers and nodejs. Friends who need it can refer to it. I hope it can help you.
axios Introduction
axios is a Promise-based HTTP client for browsers and nodejs. It has the following characteristics:
From browsing Create an XMLHttpRequest in the server
Issue an http request from node.js
- ##Support Promise API
- Interception of requests and responses
- Convert request and response data
- Cancel request
- Automatically convert JSON data
- Client supports preventing CSRF/XSRF
// 配置API接口地址
var root = 'https://cnodejs.org/api/v1'
// 引用axios
var axios = require('axios')
// 自定义判断元素类型JS
function toType (obj) {
return ({}).toString.call(obj).match(/\s([a-zA-Z]+)/)[1].toLowerCase()
}
// 参数过滤函数
function filterNull (o) {
for (var key in o) {
if (o[key] === null) {
delete o[key]
}
if (toType(o[key]) === 'string') {
o[key] = o[key].trim()
} else if (toType(o[key]) === 'object') {
o[key] = filterNull(o[key])
} else if (toType(o[key]) === 'array') {
o[key] = filterNull(o[key])
}
}
return o
}
/*
接口处理函数
这个函数每个项目都是不一样的，我现在调整的是适用于
https://cnodejs.org/api/v1 的接口，如果是其他接口
需要根据接口的参数进行调整。参考说明文档地址：
https://cnodejs.org/topic/5378720ed6e2d16149fa16bd
主要是，不同的接口的成功标识和失败提示是不一致的。
另外，不同的项目的处理方法也是不一致的，这里出错就是简单的alert

function apiAxios (method, url, params, success, failure) {
if (params) {
params = filterNull(params)
}
axios({
method: method,
url: url,
data: method === 'POST' || method === 'PUT' ? params : null,
params: method === 'GET' || method === 'DELETE' ? params : null,
baseURL: root,
withCredentials: false
})
.then(function (res) {
if (res.data.success === true) {
if (success) {
success(res.data)
}
} else {
if (failure) {
failure(res.data)
} else {
window.alert('error: ' + JSON.stringify(res.data))
}
}
})
.catch(function (err) {
let res = err.response
if (err) {
window.alert('api error, HTTP CODE: ' + res.status)
}
})
}
// 返回在vue模板中的调用接口
