postman 如何查看 request 请求的header和response参数

文章目录

问题描述

工作中，使用postman，发现返回结果不是自己想要的，但是不确定参数是否传递准确，但是又无法像chrome浏览器F12的开发者工具这样的神器，于是在网上搜了相关信息，做个笔记，方便以后学习

地址栏传递参数

查看 request请求的面板

axios 等价实现 AK / SK 代码

1. axios实例对象添加请求拦截器

// 请求拦截器
http.interceptors.request.use(function(config){getTokenInfo(config)// 在请求对象中添加 header信息returntrimOnlySpace(config)},function(error){// 对请求错误做些什么return Promise.reject(error)})

1. 利用 AxiosRequestConfig 实例对象添加头信息

import CryptoJS from'crypto-js'exportfunctiongetTokenInfo(configObj){var appKey ='22918213';//需要根据现场情况修改var appSecret ='wEEt313l0KotykQaN17f';//需要根据现场情况修改functionresetHeadersInfo(key, value){

响应后的函数 Test

// 1、Status code is 200      检查响应状态码是否为200
pm.test("Status code is 200",function(){
    pm.response.to.have.status(200);});// 2、Body matches string   检查响应中是否包含指定字符串// 例①
pm.test("Body matches string",function(){
    pm.expect(pm.response.text()).to.include(pm.variables.get("time"));// 是否包含变量time});// 例②
pm.test("Body matches string",function(){
    pm.expect(pm.response.text()).to.include("tags");// 是否包含tags});// 3、json  value  check   检查响应中json 值
pm.test("Your test name",function(){var jsonData = pm.response.json();
    pm.expect(jsonData.errmsg).to.eql("ok");// 检查json中errmsg是否等于"ok"});// 4、Is  equal  to  a  string   检查响应等于一个字符串
pm.test("Body is correct",function(){
    pm.response.to.have.body('{"errcode":0,"errmsg":"ok"}');// 是否等于{"err......}});// 5、Response   heads  Content- Type    检查是否包含 Content- Type 这种响应头
pm.test("Content-Type is present",function(){
    pm.response.to.have.header("Content-Type");});// 6、Response time  is  less  than  200ms   检查请求耗时小于200ms
pm.test("Response time is less than 300ms",function(){
    pm.expect(pm.response.responseTime).to.be.below(300);// 耗时是否小于300ms});
