[Day18] - Django-REST-Framework API 呼叫及介面操作

昨天我们使用 DRF 实作出了第一个 API -- 商品查询 API 。相信大家都有感到成就感吧！以後就可以跟人炫耀说你会用Python 建立 API 了！但其中一些部分相信大家应该是似懂非懂的状态吧，我们就一步步来带大家细部的说明。今天首先来说明怎麽样使用这个API 以及如何使用 DRF 自备的 UI 介面。

呼叫 API

在前一篇教学我们使用的 class 为 modelviewset , 此 viewset已有内建一些操作的功能可以供我们呼叫
详细资料可以参考：

GET /products/

我们使用 Python 对我们的 API 进行呼叫，
我们可以看到他回传资料库当中储存的资料:

>>> import django
>>> import requests
>>> r = requests.get('http://127.0.0.1:9000/products/')
>>> print(r.text)
[{"id":1,"name":"test","uploader":"tt","status":"tt","description":"tt","view":3,"price":4},{"id":2,"name":"test","uploader":"tt","status":"tt","description":"tt","view":3,"price":null},{"id":3,"name":"test","uploader":"tt","status":"tt","description":"tt","view":3,"price":null}]
>>>

POST /products/

透过 POST 新增 product 资料，我们一样透过 Python 来进行操作：

>>> r = requests.post('http://127.0.0.1:9000/products/', data = {'name':'test1','uploader':'jimmy'})
>>> print(r.text)
{"id":4,"name":"test1","uploader":"jimmy","status":"NEW","description":null,"view":null,"price":null}
>>> r = requests.get('http://127.0.0.1:9000/products/')
>>> print(r.text)
[{"id":1,"name":"test","uploader":"tt","status":"tt","description":"tt","view":3,"price":4},{"id":2,"name":"test","uploader":"tt","status":"tt","description":"tt","view":3,"price":null},{"id":3,"name":"test","uploader":"tt","status":"tt","description":"tt","view":3,"price":null},{"id":4,"name":"test1","uploader":"jimmy","status":"NEW","description":null,"view":null,"price":null}]
