How to give image as an user input in api request using flask in python-CodePudding

I am creating an API where I want to give image as an user input.

I know request.args.get take user input in dictionary format. I want to know if in any way user can give image as input to api in below api script.

My image path is E:\env\abc.png

a.py

import pandas as pd
from datetime import datetime
from pandas import json_normalize
from flask import request, Flask, Response
from flask_cors import CORS
app = Flask(__name__)
CORS(app)

@app.route("/api_endpoint", methods=["GET"])
def function_for_api():
    
    user_input_image = request.args.get('user_input_image')
    print("USER IMAGE",user_input_image)

    status = 200
    resJson = "python_file_name output will be here in json format"
    return Response(response=resJson, status=status, mimetype="application/json")

if __name__ == "__main__":
    app.run()

CodePudding user response：

First, this method should be a POST and not a GET. You are putting information on the server. Second, you want to read the file from the files parameter and not one of the query parameters.

@app.route("/api_endpoint", methods=["POST"])
def function_for_api():
    img = request.files['file']
    print(img.filename)
    return Response(status=200)

Here is an example of you could call this function uploading an image.

import requests
pic_file = "picture_filename"
# post a request with file and receive response
with open(pic_file, 'rb') as f:
    resp = requests.post(f"{your_server_address}/api_endpoint", files={'file': f})
