Question

因此，我创建了以下通过 ngrok 隧道传输的 HTTP 服务器，并且我尝试将文件发送到服务器，然后读取它并将其显示在服务器的网页上。这是服务器的代码：

import os

from http.server import HTTPServer, BaseHTTPRequestHandler
from pyngrok import ngrok
import time

port = os.environ.get("PORT", 80)

server_address = ("127.0.0.1", port)

class MyServer(BaseHTTPRequestHandler):
    def _set_headers(self):
        self.send_response(200)
        self.send_header('Content-type', 'text/html')
        self.end_headers()

    def do_GET(self):
        self._set_headers()
        self.wfile.write(bytes("<html><head><title>https://pythonbasics.org</title></head>", "utf-8"))
        self.wfile.write(bytes("<p>Request: %s</p>" % self.path, "utf-8"))
        self.wfile.write(bytes("<body>", "utf-8"))
        self.wfile.write(bytes("<p>This is an example web server.</p>", "utf-8"))
        self.wfile.write(bytes("</body></html>", "utf-8"))

    def do_POST(self):
        '''Reads post request body'''
        self._set_headers()
        content_len = int(self.headers.getheader('content-length', 0))
        post_body = self.rfile.read(content_len)
        self.wfile.write("received post request:<br>{}".format(post_body))
    
    def do_PUT(self):
        self.do_POST()

httpd = HTTPServer(server_address, MyServer)

public_url = ngrok.connect(port).public_url
print("ngrok tunnel \"{}\" -> \"http://127.0.0.1:{}\"".format(public_url, port))

try:
    # Block until CTRL-C or some other terminating event
    httpd.serve_forever()
except KeyboardInterrupt:
   print(" Shutting down server.")

   httpd.socket.close()

我一直在尝试使用 POST 发送文件，如下所示

>>> url = 'https://httpbin.org/post'
>>> files = {'file': open('report.xls', 'rb')}

>>> r = requests.post(url, files=files)
>>> r.text

我当然导入了请求，这就是我得到的

Exception occurred during processing of request from ('127.0.0.1', 60603)
Traceback (most recent call last):
  File "C:\Program Files\Python39\lib\socketserver.py", line 316, in _handle_request_noblock
    self.process_request(request, client_address)
  File "C:\Program Files\Python39\lib\socketserver.py", line 347, in process_request
    self.finish_request(request, client_address)
  File "C:\Program Files\Python39\lib\socketserver.py", line 360, in finish_request
    self.RequestHandlerClass(request, client_address, self)
  File "C:\Program Files\Python39\lib\socketserver.py", line 720, in __init__
    self.handle()
  File "C:\Program Files\Python39\lib\http\server.py", line 427, in handle
    self.handle_one_request()
  File "C:\Program Files\Python39\lib\http\server.py", line 415, in handle_one_request
    method()
  File "C:\Users\pierr\OneDrive\Desktop\SpyWare-20210104T124335Z-001\SpyWare\Ngrok_Test.py", line 28, in do_POST
    content_len = int(self.headers.getheader('content-length', 0))
AttributeError: 'HTTPMessage' object has no attribute 'getheader'

有人可以帮我解决这个错误吗？我不明白它来自哪里。

如何将文件发送到 HTTP 服务器并读取它？
