Postman测试Web API

如何查看查询字符串？

→输入包含查询字符串的URL，比如：http://localhost:54176/api/ProductCategories?name=darren&age=25
→点击Params，查询字符串以键值队集合的形式存储
→选中键值对，右键选择"EncodeURIComponent"可以对键或值加密


如何使用Body？

→form-data选项，输入表单数据
→x-www-form-urlencoded选项,输入表单数据，Postman自动加密
→raw选项，输入json数据

{
    "name":"",
    "username":""
    "age":25
}
→binary选项，上传图片、音频、视频等

这里准备了一些API需要测试：

GET     /categories
POST    /categories
PUT     /categories/{id}
GET     /categories/{id}
DELETE  /categories/{id}

POST    /categories/{id}/products
GET     /categories/{id}/products
DELETE  /categories/{id}/products/{productId}
GET     /categories/{id}/products/{productId}
PUT     /categories/{id}/products/{productId}


GET请求测试？

→点击No environment创建环境变量

host: http://localhost
port:8080

→GET请求

GET {{host}}:{{port}}/categories
GET {{host}}:{{port}}/categories/1
GET {{host}}:{{port}}/categories/1/products

验证授权？

验证解决是谁的问题。授权解决能做什么的问题。

通常的情形是：

POST .../auth/login

    "login":"",
    "password":""
}

→ 服务端返回token

在响应中获取到token

→ 再次请求在Headers中放入token

GET ../categories
