接口测试工具Jmter 1.用户自定义变量 2.CSV批量添加 3.函数 1.计数器函数使用计数器变量 2.随机数函数

一、Postman工具

1.Base64加解密

Base64加密：

 //base64加密
 var username=CryptoJS.enc.Utf8.parse("admin");//先转为UTF-8格式
 var base64_username=CryptoJS.enc.Base64.stringify(username);//进行Base64加密
 console.log(base64_username);

Base64解密：

 //base64解密
 var username = CryptoJS.enc.Base64.parse("YWRtaW4=");//进行解密
 var utf8_username = username.toString(CryptoJS.enc.Utf8);//转为UTF-8格式
 console.log(utf8_username);

2.MD5加密

 //MD5加密(转换为MD5加密(32位小写)，再转为字符串，并将转码后的字符串转换为32位大写)
 var MD5_username = CryptoJS.MD5("admin").toString().toUpperCase();
 console.log(MD5_username);

3.RSA加密解密

请求参数：

 {
     "code":"574526",
     "phone":"{{aes$17803878944}}",
     "cardId":"{{rsa$410922199008151440}}"
 }

Pre-request Script脚本

 if(!pm.globals.has("forgeJS")){
     pm.sendRequest("https://raw.githubusercontent.com/loveiset/RSAForPostman/master/forge.js", (err, res) => {
     if (!err) {
         pm.globals.set("forgeJS", res.text())
     }
 })}
  
 eval(postman.getGlobalVariable("forgeJS"));
 
 // ------------ AES 加密 ------------

     //盐
     const iv = CryptoJS.enc.Utf8.parse('S41AXIPFRFVJL73Z');
     const encrypted = CryptoJS.AES.encrypt(content, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7});
     return encrypted.toString();
 }
  
 //设置公钥变量

     if(pubKey){
         const publicKey = forge.pki.publicKeyFromPem(pubKey);
         const encryptedText = forge.util.encode64(
             publicKey.encrypt(content, 'RSAES-PKCS1-V1_5', {
               md: forge.md.sha1.create(),
               mgf: forge.mgf.mgf1.create(forge.md.sha1.create())

         if (option) {
             result = option.substring(2, option.length - 2)
         }
     }
     
     return result
 }
 
 // ------ 存储所有未加密环境变量 ------
 if(!pm.environment.has('localStore')){
     pm.environment.set('localStore', '{}');
 }
 let localStore = JSON.parse(pm.environment.get('localStore'));
 // 获取当前请求中的加密变量
 let requestData; 
 if((typeof request.data) === 'string'){
     requestData = JSON.parse(request.data)
 } else {
     requestData = request.data;
 }
  
 requestData = Object.assign(requestData, request.headers);
 Object.keys(requestData).map(key => {
     let value = requestData[key] + ''; // 内容
     if (value.indexOf('{{') !== -1) { // 是否为变量
         let content = getBracketStr(value);
         // 判断是否加密
         if (content.indexOf('aes$') !== -1) {
             let c = content.split('aes$')[1];
             let encryptedContent = pm.environment.get(c); // 加密内容
             encryptedContent = encryptedContent ? encryptedContent : c;
             pm.environment.set(content, aesEncrypt(encryptedContent));
             localStore[content] = aesEncrypt(encryptedContent);
         } else if (content.indexOf('rsa$') !== -1) {

             let encryptedContent = pm.environment.get(c); // 加密内容
             encryptedContent = encryptedContent ? encryptedContent : c;
             pm.environment.set(content, rsaEncrypt(encryptedContent));

         }
     }
 });
  
 pm.environment.set('localStore', JSON.stringify(localStore));
 console.log(JSON.stringify(localStore))

服务端处理：

 AES aes = new AES("CBC", "PKCS7Padding",
                   // 密钥，可以自定义
                   "Y5MUIOM7BUWI7BQR".getBytes(),
                   // iv加盐，按照实际需求添加
                   "S41AXIPFRFVJL73Z".getBytes());
 log.info("phone解密前：【{}】", loginForm.getPhone());
 byte[] decryptPhone = aes.decrypt(loginForm.getPhone());
 log.info("phone解密后：【{}】", new String(decryptPhone));
 
 
 
 log.info("cardId解密前：【{}】", loginForm.getCardId());
 RSA rsa = new RSA(RSAEncryptConfig.PRIVATEKEY, null);
 byte[] cardId = rsa.decrypt(loginForm.getCardId(), KeyType.PrivateKey);
 log.info("cardId解密后：【{}】", new String(cardId));

4.接口关联

 //获取返回的json数据
 var jsonData = pm.response.json();
 var token = jsonData.token;
 pm.collectionVariables.set("token", token);

5.断言

 pm.test("Status code is 200", function () {
     pm.response.to.have.status(200);
 });
 
 pm.test("Your test name", function () {
     var jsonData = pm.response.json();
     pm.expect(jsonData.value).to.eql(100);
 });

6.解析请求数据和响应数据

 //解析请求数据
 var requestData = JSON.parse(request.data);
 
 //解析响应数据
 var responseData = JSON.parse(responseBody);

7.设置时间戳

 //设置当前时间戳毫秒
 postman.setGlobalVariable("timestamp",Math.round(new Date().getTime()));

8.加签和验签

加签

 //获取请求数据
 var data = JSON.parse(request.data)
 //请求时间戳
 var reqTime = Math.round(new Date().getTime());
 pm.collectionVariables.set("reqTime",reqTime);
 data.reqTime = reqTime;
 //连接符
 var join = '&';
 var result = '';
 //键按首字母排序
 let keys = Object.keys(data).sort();
 for(var i = 0; i < keys.length; i++){
     let key = keys[i];
     let value = data[key] + '';
     if(value.indexOf('{{') !== -1) continue;
     result = result + key + '=' + value + join;
 }
