I wanted to POST json and images with python, so I summarized them all. I receive them all in Flask.

First of all, POST data normally

`post.py`


import requests
import json

post_url = "http://127.0.0.1:5000/callback"

#Data you want to post
data = "wowwowwowwow"

#POST transmission
response = requests.post(
                    post_url,
                    data = data
                    )

print(response.json())

`server.py`


from flask import *
import os
from PIL import Image
import json

app=Flask(__name__)

@app.route("/")
def hello():
    return "hello"

@app.route("/callback",methods=["POST"]) 
def callback():
    print(request.data.decode())
    return jsonify({"kekka": "I received it!"})

if __name__=="__main__":
    port=int(os.getenv("PORT",5000))
    app.debug=True
    app.run()

POST in JSON format

`post.py`


import requests
import json

post_url = "http://127.0.0.1:5000/callback"
                
json = {"data": "Woooooo"}

#POST transmission
response = requests.post(
                    post_url,
                    json = json,
                    )

print(response.json())

`server.py`


from flask import *
import os
from PIL import Image
import json

app=Flask(__name__)

@app.route("/")
def hello():
    return "hello"

@app.route("/callback",methods=["POST"]) 
def callback():
    data = request.data.decode('utf-8')#Decode
    data = json.loads(data)
    print(data["data"])
    return jsonify({"kekka": "I received it!"})

if __name__=="__main__":
    port=int(os.getenv("PORT",5000))
    app.debug=True
    app.run()

POST image

`post.py`


import requests
import json

post_url = "http://127.0.0.1:5000/callback"
                
#Read the file to POST
files = { "image_file": open('./sample.jpg', 'rb') }

#POST transmission
response = requests.post(
                    post_url,
                    files = files,
                    )

print(response.json())

`server.py`


from flask import *
import os
from PIL import Image
import json

app=Flask(__name__)

@app.route("/")
def hello():
    return "hello"

@app.route("/callback",methods=["POST"]) 
def callback():
    #Loading images
    im = Image.open(request.files["image_file"])

    #display
    im.show()
    
    return jsonify({"kekka": "I received it!"})

if __name__=="__main__":
    port=int(os.getenv("PORT",5000))
    app.debug=True
    app.run()
