Ajax-interface-checker NPM

ajax-interface-checker

Introduction

ajax-interface-checker module would offer your all supports in http request ,
which contains http request methods 、 http error throw and catch module 、
http proxy module and http window module .

When you are developing you program , you could use ajax-interface-checker 
to setting mock data 、test your page when different errors happened 、and 
use real runtime window to show it .

Note that , i used `Promise` 、 `Map` and other ES6 feathers , but i do NOT 
import their compatible code , because i suppose that you would do it in your
project . Right ?

module

HttpAuth

`HttpAuth` module helps you to auth your ajax result , but it aimed to handle
common logic for your ajax code .

Use Pattern

HttpAuth(ajaxRes , <statusKey> , <messageKey> , <dataKey>) ;

How to use

import { HttpAuth } from "ajax-interface-checker" ;
// normal ajax result mock 
let mockRes = { code : 0 , message : 'ok' , data : {} } ;
HttpAuth(mockRes) ; // mockRes.data
// error ajax result mock
let mockResError = { code : -1 , message : 'database connect error' } ;
HttpAuth(mockResError) ; // mockRes.data

==================================

Http

Http offers three basic methods , get 、post and jsonp , to get server data .
I use axios and jsonp module to do these . You could use theme as bellow . 

And I would offer cache control , but you should be more careful to USE it .  

I would also offer http error test , you could use `options.hasOpenError` to run it 
as bellow value .

Use Pattern

let http = new Http(<options>) ;
http.auth = function(){} ;
// get
http.get(pathname , <params> , <options> , <baseHost> ) ;
// post
http.post(pathname , <data> , <params> , <options> , <baseHost>) ;
// jsonp
http.jsonp(pathname , <params> , <options> , <baseHost>) ;

You could rewrite http.auth to auth your ajax result , especially some same error logic handler .
http.get method overcames a get request . - pathname sets pathname of your get request , link '/getNameList' - params sets params , which your want to catch , it is a object . - options sets basic options of ajax - cache controls whether to use ajax cache - cacheCount sets the max count of ajax cache - hasOpenError whether to open error test - baseHost sets base host of your get request , link "//localhost" .
http.post method overcames a post request . - pathname sets pathname of your post request , link '/getNameList' - data sets data , which your want to catch , it is a object . - params sets params , which your want to catch , it is a object . - options sets basic options of ajax for example cache 、 cacheCount and so on . - cache controls whether to use ajax cache - cacheCount sets the max count of ajax cache - hasOpenError whether to open error test
- baseHost sets base host of your get request , link "//localhost" .
http.jsonp method overcames a jsonp request . - pathname sets pathname of your jsonp request , link '/fetchNameList' - params sets params , which your want to catch , it is a object . - options sets basic options of ajax for example cache 、 cacheCount and so on . - cache controls whether to use ajax cache - cacheCount sets the max count of ajax cache - hasOpenError whether to open error test
- baseHost sets base host of your jsonp request , link "//localhost" .

How to use

In your config.js file , you should use NODE_ENV to setting different env about 
server setting .

config.js

var env = (process.env.NODE_ENV || "development").trim() ;

var config = {
	env: env ,
} ;
switch (env){
	case 'production' :
		Object.assign(config , {
			'protocol': 'https' ,
			'NODE_ENV': env ,
			'apihost' : '' ,
			'domain'  : ''
		}) ;
		break ;
	default : 
		Object.assign(config , {
			'protocol': 'http' ,
			'NODE_ENV': env ,
			'apihost' : '' ,
			'domain'  : ''
		}) ;
		break ;
} ;
module.exports = config ;

client useage

utils/ajax.js

import { Http } from "ajax-interface-chekcer" ;
let http = new Http({
	apihost : "//localhost" ,
	jsonpHost : "//localhost"
}) ;
// reset ajax data auth
http.auth = function(res){
	let { code = 0 , data = {} , message = 'ok' } = res ;
	switch(code){
		case 0 :
			return data ;
		case -1 :
		default :
			console.log("ajax interface error");
			return res ;
	}
} ;
http.get('/getList' , { page : 1 , pagesize : 20 } , {cache : true}).then(data => data) ;
http.post('/fetchList' , { page : 1 , pagesize : 20 } , {cache : true}).then(data => data) ;
http.jsonp('/getList' , { page : 1 , pagesize : 20 } , {cache : true}).then(data => data) ;

server useage

I would use `request` module to run server ajax , like form node to java .

import { Http } from "ajax-interface-checker" ;
import config from "../../config/index" ;
import httpCommonFail from "./httpCommonFail" ;
import request from "request" ;
import auth from "./auth" ;

// config http ajax aim source url
let httpInstance = new Http({
  apihost : config.apihost ,
  jsonpHost : config.jsonphost
}) ;

// default server exception catch ,
// this catching function had been overcomed in ajax-interface-checker ,
// you can rewrite it if you need .
httpInstance.httpCommonFail = httpCommonFail ;

// default interface exception catch ,
// this catching function had been overcomed in ajax-interface-checker ,
// you can rewrite it if you need .
httpInstance.auth = auth ;

// rewrite http request method to run node request 
httpInstance.request = function(params = {}){
	return new Promise((resolve , reject) => {
		request(params , function(err , response , body = ""){
			// err reject
			if(err){
				reject(err) ;
				return ;
			}
			// response
			if(response.statusCode * 1 === 200){
				let res = null ;
				// 兼容返回的不是对象的问题
				try {
					res = JSON.parse(body) ;
				}catch(err){
					res = {
						state : 0 ,
						code : 0 ,
						data : body
					}
				}
				resolve({ data : res }) ;
			}
		}) ;
	}) ;
}
