[fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) based asynchronous request function for the browser and node.js HTTP client.
## Browser Support
xe-ajax Depends on a native [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) implementation to be supported. If your environment doesn't support Promises, you can babel-polyfill or bluebird.js.

```
### jsonp
```JavaScript
import XEAjax from 'xe-ajax'
// Case 1:
// http://test.com/api/jsonp/public/message?callback=jsonp_xeajax_1521272815608_1
// jsonp_xeajax_1521272815608_1({message: 'success'})
XEAjax.fetchJsonp('/api/jsonp/public/message')
.then(response => {
if (response.ok) {
response.json().then(data => {
// data
})
}
})
// Case 2:
// http://test.com/api/jsonp/public/message?cb=jsonp_xeajax_1521272815608_2
// jsonp_xeajax_1521272815608_2({message: 'success'})

.then(data => {
// data
})
```
### Multiple Requests
```JavaScript
import XEAjax from 'xe-ajax'
Promise.all([
XEAjax.fetchGet('/api/test/message/list'),
XEAjax.doGet('/api/test/message/list'),
XEAjax.post('/api/test/message/save'), {name: 'n1'})
]).then(datas => {
// all finish
}).catch(e => {
// error
})
Promise.race([
XEAjax.get('/api/test/message/list'),
XEAjax.get('/api/test/message/list')
]).then(datas => {
// finish
}).catch(e => {
// error
})
// doAll Use object parameters, The use is consistent with that of Promise.
let iterable2 = []
iterable2.push({url: '/api/test/message/list'})
iterable2.push({url: '/api/test/message/save', body: {name: 'n1'}}, method: 'POST'})
XEAjax.doAll(iterable2).then(datas => {
// all finish
}).catch(e => {
// error
})
```
### Nested Requests
```JavaScript
import XEAjax from 'xe-ajax'
// This should be avoided in the project.
XEAjax.fetchGet('/api/test/message/info', {id: 3})
.then(response => response.json())
.then(data => XEAjax.fetchGet(`/api/test/message/delete/${data.id}`))
.then(response => {
if (response.ok) {
response.json().then(data => {
// data
})
}
})
XEAjax.doGet('/api/test/message/info', {id: 3})
.then(result => XEAjax.doGet(`/api/test/message/delete/${result.data.id}`))
.then(result => {
// result.data
})
XEAjax.get('/api/test/message/info', {id: 3})
.then(data => XEAjax.get(`/api/test/message/delete/${data.id}`))
.then(data => {
// data
})
```
## Promises, async/await
```JavaScript
import XEAjax from 'xe-ajax'
async function init() {
let list = await XEAjax.get('/api/test/message/list')

// Set params
// Request.params.version = Date.now()
// Set Token validation to prevent XSRF/CSRF attacks.
request.headers.set('X-Token', cookie('x-id'))

put (url, data, request) {
return XEAjax.doPut(url, data, request)
}
})
XEAjax.get('/api/test/message/list', {params: {id: 123}})
XEAjax.delete('/api/test/message/delete/123')
XEAjax.post('/api/test/message/save', {name: 'test1'})
