直接上程式碼

1、伺服器介面

import flask, os,sys,time

from flask import request, send_from_directory

interface_path = os.path.dirname(__file__)

sys.path.insert(0, interface_path) #將當前檔案的父目錄加入臨時系統變數

server = flask.Flask(__name__)

#get方法：指定目錄下載檔案

@server.route("/download", methods=["get"])

def download():

fpath = request.values.get("path", "") #獲取檔案路徑

fname = request.values.get("filename", "") #獲取檔名

if fname.strip() and fpath.strip():

print(fname, fpath)

if os.path.isfile(os.path.join(fpath,fname)) and os.path.isdir(fpath):

return send_from_directory(fpath, fname, as_attachment=True) #返回要下載的檔案內容給客戶端

else:

return "{"msg":"引數不正確"}"

else:

return "{"msg":"請輸入引數"}"

# get方法：查詢當前路徑下的所有檔案

@server.route("/getfiles", methods=["get"])

def getfiles():

fpath = request.values.get("fpath", "") #獲取使用者輸入的目錄

print(fpath)

if os.path.isdir(fpath):

filelist = os.listdir(fpath)

files = [file for file in filelist if os.path.isfile(os.path.join(fpath, file))]

return "{"files":"%s"}" % files

# post方法：上傳檔案的

@server.route("/upload", methods=["post"])

def upload():

fname = request.files.get("file") #獲取上傳的檔案

if fname:

t = time.strftime("%Y%m%d%H%M%S")

new_fname = r"upload/" + t + fname.filename

fname.save(new_fname) #儲存檔案到指定路徑

return "{"code": "ok"}"

else:

return "{"msg": "請上傳檔案！"}"

server.run(port=8000, debug=True)

2、客戶端請求

import requests

import os

#上傳檔案到伺服器

file = {"file": open("hello.txt","rb")}

r = requests.post("http://127.0.0.1:8000/upload", files=file)

print(r.text)

#查詢fpath下的所有檔案

r1 = requests.get("http://127.0.0.1:8000/getfiles",data={"fpath": r"download/"})

print(r1.text)

#下載伺服器download目錄下的指定檔案

r2 = requests.get("http://127.0.0.1:8000/download",data={"filename":"hello_upload.txt", "path": r"upload/"})

file = r2.text #獲取檔案內容

basepath = os.path.join(os.path.dirname(__file__), r"download/")

with open(os.path.join(basepath, "hello_download.txt"),"w",encoding="utf-8") as f: #儲存檔案

f.write(file)
