Vue is recommended axios a network request: Vue project recently started again, return to it. Several methods axios from the beginning of it.
1. Installation: Since it is a Vue project, I chose common way npm
$ npm install axios (-d)
2. Introduction: const axios = require ( 'axios') or transformed with ESmodule babel manner const axios = import ( 'axios')
3. Request: GET request, the request method is very flexible:
axios.get ( '/ user? ID = 12345') ---------------------- URL parameter carries a way
axios.get ( '/ user', {params: {ID: 12345}}) ------- mode parameter object
Note: Returns are processed promise ------ Here are two ways to return
.. A Promise.then () catch in the form of:
axios.get('/user',{param:{ID:12345}}).then(response => {console.log(response)})
b. async function getUser() {
try {
const response = await axios.get('/user',{ param:{ ID:12345} })
} catch (e) {
console.log(e)
}
}
Post Request: parameter object passed embodiment according to
axios.post ( '/ user', {name: "Joe Smith", age: "18"}) Note: param there is no direct way to pass the object on it.
4. Concurrent Request
fucntion getUser（）{
axios.get('/user/1234')
}
fucntion getPermission （）{
axios.get('/user/1234/permissions')
}
axios.all ([getUser, getPermission]). then (axios.spread (function (acct, perms) {----. then method, call axios.spread method parameter function, which accepts two parameters acct pe
// These two parameters, respectively, two return request.
})) ------- Promise i.e. an array of sources of error function capturing catch, to be investigated ---
The basic configuration is provided comprising a head and other commonly used baseUrl baseUrl axios.creat ({config} objects)
axios.creat ({
baseURL: 'http: //some-domain.com/api/', // url basis to determine the configuration of the operating environment by webpack, you can change the online address, the address prefix development
timeout: 1000, // response timeout
headers:{Content-Type:application/x-www-form-urlencoded } // 请求头
})
