请求数据类型

data

request.post(
url='xx',
data={'k1':'v1,'k2':'v2'}
)
#数据： POST / http1.1\r\n....\r\n\r\nk1=v1&k2=v2

request.post(
url='xx',
data=json.dumps({'k1':'v1,'k2':'v2'})
)

#数据：  POST /  http1.1\r\n....\r\n\r\n{'k1':'v1,'k2':'v2'}

　字节

request.post(
url='xx',
data=b'asdfasdf'
)
#数据： POST / http1.1\r\n....\r\n\r\n'asdfasdf'

　json

request.post(
url='xx',
json={'k1':'v1,'k2':'v2'}
)
#数据： POST / http1.1\r\nContent-type:application/json....\r\n\r\n{'k1':'v1,'k2':'v2'}

问题：POST请求发数据

django：获取不到值？request.POST

发送数据格式：

方式一：
request.post(
url='xx',
data={'k1':'v1,'k2':'v2'}
)
#数据： POST / http1.1\r\nContent-type:urlencode-form.......\r\n\r\nk1=v1&k2=v2

request.POST必然可以获取到值。

- content-type: urlencode-form
- 数据格式：k1=v1&k2=v2

方式二：

request.post(
url='xx',
json={'k1':'v1,'k2':'v2'}
)
#数据： POST / http1.1\r\nContent-type:application/json....\r\n\r\n{'k1':'v1,'k2':'v2'}

通过request.body

字节 = {'k1':'v1,'k2':'v2'}
字节转换字符串
反序列化字符串 -> 字典

request.POST必然不可以获取到值。

- content-type: urlencode-form
- 数据格式：k1=v1&k2=v2
