Wraps almost all of official APIs, see Wrapped methods

Enhancements

Create http request shortcuts according to wechat mini-program declared verbs(RFC 2616). specially, the PATCH verb maybe useful for strict RESTful-ist, and so it has defined also.

weapp.request

It resolves a response which take a statusCode in range of [200, 300), and reject a response which out of the range.

The resolved response and rejected reason/error is the response object from the native wx.request.

import weapp from 'weapp-next'const {request} = weapp(wx)request({url, method: 'GET'}) .then(response => { // response is the response object from wx.request }) .catch(error => { // error is the response object from wx.request })request.get(url:String [, init:Function])request.post(url:String, body:String/Object, [, init:Function])request.put(url:String, body:String/Object, [, init:Function])request.patch(url:String, body:String/Object, [, init:Function])request.delete(url:String [, init:Function])request.head(url:String [, init:Function])request.options(url:String [, init:Function])request.trace(url:String [, init:Function])request.connect(url:String [, init:Function])

Optional init argument is a zero-arugments function to interpolate request parameters, and it expects to return an Object value by contract. you can override any request params by the returned object except the url and method.

// logic of init functionconst config = {...}return {...config, ...init(), url, method}

weapp.requireAuth (DPRECIATED)

DPRECIATED

Here is a Express middleware for weapp login scenario which purpose to make it easy to integrate weapp login and getUserInfo logic. express-weapp-auth

Use RESTful Http client

import weapp from 'weapp-next'const http = weapp(wx).Http('https://api.server.com/')http.get('/status', {version: '1'}) // /status?version=1http.post('/status', {data: {}})
