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

bash 复制代码

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

bash 复制代码

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

bash 复制代码

<body>

<div class="">

</div>
<script type="text/javascript">

    $(function() {
        requestGetLoginDemo();
        requestPostLoginDemo();
    });

    function requestGetLoginDemo() {
        var data = { username: "myyhtw", password: "123456"}
        getAjaxRequst('/auth/login', data, function(res) {
            console.log(res)
            if(res){
                console.log("需要的数据")
            } else {
                console.log("返回数据不存在或者请求数据失败")
            }
        })
    }

    function requestPostLoginDemo() {
        var data = { username: "myyhtw", password: "123456"}
        postAjaxRequst('/auth/login', data, function(res) {
            console.log(res)
            if(res){
                console.log("需要的数据")
            } else {
                console.log("返回数据不存在或者请求数据失败")
            }
        })
    }

    
</script>

</body>

</html>

后端使用SpringBoot写了get和post请求登录的2个接口示例

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

bash 复制代码

// 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)
    })
};

index.html

bash 复制代码

$(function() {
    requestJsonGetLoginDemo();
    requestJsonPostLoginDemo();
});

function requestJsonGetLoginDemo() {
    var username = "myyhtw"; 
    var password = "123456";
    getAjaxJsonHttpRequst('/auth/login/'+username+"/"+password, null, null, function(res) {
        console.log(res)
        if(res){
            console.log("需要的数据")
        } else {
            console.log("返回数据不存在或者请求数据失败")
        }
    })
}

function requestJsonPostLoginDemo() {
    var data = { username: "myyhtw", password: "123456"}
    postAjaxJsonHttpRequst('/auth/login', data, null, function(res) {
        console.log(res)
        if(res){
            console.log("需要的数据")
        } else {
            console.log("返回数据不存在或者请求数据失败")
        }
    })
}
