PythonでいろいろPOSTしてFlaskで受け取る

Posted at

pythonでjsonとか画像とかPOSTしたくなってきたので, 全部まとめました。全部Flaskで受け取ってます。

#まずは普通にdataをPOST

post.py
import requests
import json

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

#postしたいデータ
data = "wowwowwowwow"

#POST送信
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": "受け取ったよ!"})

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

#JSON形式でPOST

post.py
import requests
import json

post_url = "http://127.0.0.1:5000/callback"
                
json = {"data": "ウオオオオお"}

#POST送信
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')#デコード
    data = json.loads(data)
    print(data["data"])
    return jsonify({"kekka": "受け取ったよ!"})

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

#画像をPOST

post.py
import requests
import json

post_url = "http://127.0.0.1:5000/callback"
                
#POSTするファイルの読込
files = { "image_file": open('./sample.jpg', 'rb') }

#POST送信
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():
    #画像の読み込み
    im = Image.open(request.files["image_file"])

    #表示
    im.show()
    
    return jsonify({"kekka": "受け取ったよ!"})

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

#感想
これであなたもPOSTマスター。
