基于Flask传输字符串/图像

传输字符串

服务端

from flask import Flask,request

app = Flask(__name__)

@app.route("/delimgs",methods = ['GET', 'POST']) # 路由

def _server():
    if request.method == "POST":
        delname = request.form.get('delname')
        return {''text': delname}
    else:
        return "<h1>please use post !</h1>"

if __name__ == "__main__":
    host = '0.0.0.0'
    port = '8082'
    app.run(debug=True, host=host, port=port)

客户端（请求）

import requests

s = requests
data={'delname':'test.jpg'}
r = s.post('http://0.0.0.0:8082/delimgs', data)

print(r.text)

 传输图像

服务端

from flask import Flask, request

app = Flask(__name__)

@app.route("/imgsimilar",methods = ['GET', 'POST'])

def get_similar_img():
    if request.method == "POST":
        temp_img_base64 = request.form.get('imgbase64')

        rand_img_name = ‘test.jpg’
        file = open(temp_img_path,'wb')
        file.write(temp_img_base64)
        file.close()
        return {'sign':1, 'text’:’schuss’}
    else:
        return "<h1>Get similar img, please use pust !</h1>"

if __name__ == "__main__":
    host = '0.0.0.0'
    port = '8082'
    app.run(debug=True, host=host, port=port)
