• jQuery+AJAX请求的统一封装

    记录一下使用jQuery+AJAX对http请求的统一封装

    很久都没有使用jquery和ajax的组合了，这里记录一下jquery和ajax的组合简单封装 将来或许有机会重新启用这个组合

    新建jquery.request.js；demo目录结构如下
    myw

    
const baseURL = 'http://127.0.0.1:8116';

//  const baseURL = "";

const timeout = 3000;

// requet ajax
function request (url, method, data = {}, contentType, back){
    $.ajax({
        url: baseURL+url,
        type: method,
        data: data,
        cache: false,
        timeout: timeout,
        contentType: contentType,
        dataType: "json",
        success: function(res){
            console.log(res)
            return typeof back == "function" && back(res);
        },
        error: function(error) {
            console.log(error)
            return typeof back == "function" && back(null);
        }
    });   
};
function getAjaxRequst (url, data, callBack) {
    request(url, "GET", data, "application/x-www-form-urlencoded;charset=UTF-8", function(res) {
        return typeof callBack == "function" && callBack(res)
    })
};
function postAjaxRequst (url, data, callBack) {
    request(url, "POST", data, "application/x-www-form-urlencoded;charset=UTF-8", function(res) {
        return typeof callBack == "function" && callBack(res)
    })
};

    index.html里jquery的引用必须放在request的前面

        <script type="text/javascript" src="jquery.min.js"></script>

    myw
    myw
    这里使用的是application/x-www-form-urlencoded;charset=UTF-8，一般我们使用的都是json数据，于是呢可以改变下jquery.request.js

    application/json;charset=UTF-8

    // requet ajax json token
function httpJsonRequest (url, method, data = {}, token, contentType, back){
    $.ajax({
        url: baseURL+url,
        type: method,
        data: JSON.stringify(data),
        cache: false,
        timeout: timeout,
        headers: {'token': token},
        contentType: contentType,
        dataType: "json",
        success: function(res){
            console.log(res)
            return typeof back == "function" && back(res);
        },
        error: function(error) {
            console.log(error)
            return typeof back == "function" && back(null);
        }
    });   
};
function getAjaxJsonHttpRequst (url, data, token, callBack) {
    httpJsonRequest(url, "GET", data, token, "application/json;charset=UTF-8", function(res) {
        return typeof callBack == "function" && callBack(res)
    })
};
function postAjaxJsonHttpRequst (url, data, token, callBack) {
    httpJsonRequest(url, "POST", data, token, "application/json;charset=UTF-8", function(res) {
        return typeof callBack == "function" && callBack(res)
