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：
→ 输入用户名和密码
POST .../auth/login
Headers:
Content-Type: application/json
Body:
{
"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
Headers:
token:.....
Content-Type: application/json
