Using Python to send JSON over HTTP

Because of the need to post some data to the server through the HTTP protocol, so I wrote a small program with Python, did not expect to encounter some problems, so here is the problem to record.

First on the source code:

Import urllib.request
Import json


data = {
' SSID ': ' 123 ',
' passwd ': ' 456 '
}
values = Urllib. Parse.urlencode (data). Encode (encoding= ' UTF8 ')//NOTE 1
headers = {' Content-type ': ' Application/json '}
print ( Data print (values) print (Json.dumps (data)
)
print (Json.dumps (data). Encode ())
request = Urllib.request.Request (url= ' url ', headers=headers, data=json.dumps (data) encode ())
response = Urllib.request.urlopen (Request)

We are using a JSON-formatted request for Python3,post, so:

Import Urllib.request
Import JSON

Headers is the token of JSON

Because

Urllib.request.Request

The data for the post must be bytes format, and Json.dumps is actually converted to STR, so it needs to be. Encode () further converted to bytes for transmission

In addition, note 1 is another way I look up the internet, but I try unsuccessfully. From the output, it changes the dictionary structure and can take a closer look.
