Postman測試Web API

 

如何查看查詢字符串？

→輸入包含查詢字符串的URL，好比：http://localhost:54176/api/ProductCategories?name=darren&age=25
→點擊Params，查詢字符串以鍵值隊集合的形式存儲
→選中鍵值對，右鍵選擇"EncodeURIComponent"能夠對鍵或值加密


如何使用Body？

→form-data選項，輸入表單數據
→x-www-form-urlencoded選項,輸入表單數據，Postman自動加密
→raw選項，輸入json數據

{
    "name":"",
    "username":""
    "age":25
}
→binary選項，上傳圖片、音頻、視頻等

這裏準備了一些API須要測試：

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請求測試？

→點擊No environment建立環境變量

host: http://localhost
port:8080

→GET請求

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

驗證受權？

驗證解決是誰的問題。受權解決能作什麼的問題。

一般的情形是：

→ 輸入用戶名和密碼

POST .../auth/login


Headers:

Content-Type: application/json

Body:

{
    "login":"",
    "password":""
}

→ 服務端返回token

在響應中獲取到token

→ 再次請求在Headers中放入token

GET ../categories

Headers:

Content-Type: application/json
