Postman是一款强大的API测试工具,支持多种请求方法和格式,帮助开发人员轻松测试和调试API。文章详细介绍了Postman的安装方法、基本使用和高级功能,包括环境变量设置和协作开发。
Postman 是一款强大的工具,主要用于测试API接口和进行Web服务的调试。它支持多种请求方法和格式,并可以轻松地查看响应数据。Postman可以帮助开发人员和测试人员轻松地测试和调试API,同时也能帮助产品经理了解API的设计和实现情况。此外,Postman还提供了一系列协作功能,方便团队成员共享测试用例和文档。
Postman支持Windows、Mac、Linux和Chrome浏览器,能够满足不同操作系统用户的需要。
启动Postman后,可以看到主界面中主要分为以下几个部分:
http://jsonplaceholder.typicode.com/users
。在请求体区域中输入请求数据,例如:
{ "name": "John Doe", "username": "johndoe", "email": "johndoe@example.com", "address": { "street": "21 Jump Street", "suite": "Apt. 302", "city": "New York", "zipcode": "10001" }, "phone": "123-456-7890", "website": "johndoe.com", "company": { "name": "Acme Inc.", "catchPhrase": "Making the world a better place", "bs": "Innovative solutions" } }
http://jsonplaceholder.typicode.com/users
。http://jsonplaceholder.typicode.com/users
。在请求体区域中输入请求数据,例如:
{ "name": "Jane Doe", "username": "janedoe", "email": "janedoe@example.com", "address": { "street": "123 Main Street", "suite": "Apt. 401", "city": "Los Angeles", "zipcode": "90001" }, "phone": "098-765-4321", "website": "janedoe.com", "company": { "name": "Bazooka Corp.", "catchPhrase": "Innovative technology", "bs": "Disruptive solutions" } }
在环境变量中添加变量,例如:
baseURL
: http://jsonplaceholder.typicode.com
userId
: 12345
pm.environment.set("baseURL", "http://jsonplaceholder.typicode.com"); pm.environment.set("userId", 12345);
在请求URL中使用环境变量,例如:
{{baseURL}}/users/{{userId}}
{ "userId": "{{userId}}", "title": "User {{userId}} details" }
在请求URL中使用环境变量,例如:
{{baseURL}}/users/{{userId}}
在测试脚本区输入脚本,例如:
pm.test("Status code is 200", function() { pm.response.to.have.status(200); }); pm.test("Response time is less than 200ms", function() { pm.expect(pm.response.responseTime).to.be.below(200); }); pm.test("User ID matches", function() { var jsonData = pm.response.json(); pm.expect(jsonData.id).to.be.equal(pm.environment.get("userId")); });
pm.test("Status code is 200", function() { pm.response.to.have.status(200); }); pm.test("Response time is less than 200ms", function() { pm.expect(pm.response.responseTime).to.be.below(200); }); pm.test("User ID matches", function() { var jsonData = pm.response.json(); pm.expect(jsonData.id).to.be.equal(pm.environment.get("userId")); });
pm.test("User ID matches", function() { var jsonData = pm.response.json(); pm.expect(jsonData.id).to.be.equal(pm.environment.get("userId")); });
在脚本区输入脚本,例如:
pm.environment.set("userId", pm.environment.get("userId") + 1);
在脚本区输入脚本,例如:
pm.test("Status code is 200", function() { pm.response.to.have.status(200); }); pm.test("Response time is less than 200ms", function() { pm.expect(pm.response.responseTime).to.be.below(200); }); pm.test("User ID matches", function() { var jsonData = pm.response.json(); pm.expect(jsonData.id).to.be.equal(pm.environment.get("userId")); });
pm.test("Status code is 200", function() { pm.response.to.have.status(200); }); pm.test("Response time is less than 200ms", function() { pm.expect(pm.response.responseTime).to.be.below(200); }); pm.test("User ID matches", function() { var jsonData = pm.response.json(); pm.expect(jsonData.id).to.be.equal(pm.environment.get("userId")); });

pm.test("Status code is 200", function() { pm.response.to.have.status(200); }); pm.test("Response time is less than 200ms", function() { pm.expect(pm.response.responseTime).to.be.below(200); }); pm.test("User ID matches", function() { var jsonData = pm.response.json(); pm.expect(jsonData.id).to.be.equal(pm.environment.get("userId")); });
Ctrl+Enter
发送请求,Ctrl+Shift+P
打开命令面板。pm.test("Status code is 200", function() { pm.response.to.have.status(200); }); pm.test("Response time is less than 200ms", function() { pm.expect(pm.response.responseTime).to.be.below(200); }); pm.test("User ID matches", function() { var jsonData = pm.response.json(); pm.expect(jsonData.id).to.be.equal(pm.environment.get("userId")); });
