JS performs Base64 encoding, MD5 encryption and URL encoding to realize the signature verification of express bird API interface

Keywords: Javascript JQuery JSON Java PHP

Some netizens left a message saying that they wanted to call the express bird API interface to realize Express query, but they didn't understand the back-end development, JAVA, PHP, C and python. They asked me if I could realize express interface query, and I said what would you do, he said, I only know a little bit about JS. I replied that it's enough. Now I'll tell you how to query more than 600 logistics tracks through JS.

You just need to create a new Text, copy the following code, replace your own express bird ID and APIkey, change the txt suffix to HTML, and preview with a browser to see the effect.

<!DOCTYPE html>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title>JS Call express bird API Interface</title>
    <meta charset="utf-8" />
    <script src="/base64.js"></script>
    <script src="/md5.js"></script>
    <script src="/jquery.json-2.2.min.js"></script>
    <script src="/common.js"></script>
    <script type="text/javascript">

        function GetAPI() {      
            var key="Express bird API Key";
            var id = "Express bird registration ID Number";
            var requestData="{'OrderCode':'','ShipperCode':'ZTO','LogisticCode':'78120038107849'}";
            //MD5 encryption
            var md5str = md5(requestData + key).toLowerCase();
            var dataSign = Base64.encode(md5str);
            //Splicing string (express bird request message format) url code 
            var reqData = "RequestData=" + escape(requestData) + "&EBusinessID=" + id + "&RequestType=1002&DataSign=" + escape(dataSign) + "&DataType=2";    
            //reqData = "RequestData=%7b%27OrderCode%27%3a%27%27%2c%27ShipperCode%27%3a%27ZTO%27%2c%27LogisticCode%27%3a%2778120038107849%27%7d&EBusinessID=1264783&RequestType=1002&DataSign=NzMxNTAzZWYxYTJiOGIyMDhiNTVjMTc4MDQ0NjdlZDg%3d&DataType=2";

                method: 'post',
                url: '/api/dist',
                data: reqData,
                beforeSend: function (xhr) {
                    //Trigger before calling, such as loading effect, etc
                success: function (data, status) {
                    if (status) {
                        document.getElementById("msg").innerHTML = "";
                        for (var i = 0,
   len = data.Traces.length; i < len; i++) {

                            var acceptTime = data.Traces[i].AcceptTime;
                            var acceptStation = data.Traces[i].AcceptStation;
                            //The display effect of the page is developed by ourselves, and only the function is realized here
                            document.getElementById("msg").innerHTML += acceptTime + "&nbsp;&nbsp;" + acceptStation+"<br/>";
                error: function (data, status, e) {
                    if (data.status == "401") {



    <input id="Button1" onclick="GetAPI();" type="button" value="JS Call express bird API Interface" />

    <div id="msg"></div>

The operation effect is as follows:

be careful:

<script src="/base64.js"></script>
<script src="/md5.js"></script>
<script src="/jquery.json-2.2.min.js"></script>

These three js file references, which can be downloaded online, are all general js. If you have better suggestions, please leave a message below to discuss.
