Flask的files方法可用于传各类文件，此处以传输视频为例。
客户端代码：（重点关注files组装方法）
import requests
import json
with open(‘./666051400.mp4‘,‘rb‘) as f:
video_data = f.read()
files = {‘video‘:video_data}
data = {‘video_type‘:‘mp4‘,‘unique_msg‘:‘yfqtest0328‘,‘add_sign‘:0}
r = requests.post(‘http://127.0.0.1:8000/searchmp4‘, data, files=files)
print(json.loads(r.text))
服务端代码：（重点关注files接收方法）
from flask import Flask,request
import os
app = Flask(__name__)
@app.route("/searchmp4",methods = [‘GET‘, ‘POST‘])
def searchmp4():
if request.method == "POST":
video_type = request.form.get(‘video_type‘)
video_data = request.files["video"]
video_data.save(‘123.mp4‘)
if os.path.exists(‘123.mp4‘):
print(‘文件传输成功‘)
