いくつかのWebページを返す非常に単純なpython Webサーバーがあり、TypeError: 'str' does not support the buffer interface. これが私のコードです。何が間違っているのか誰にもわかりますか?

from os import curdir
from os.path import join as pjoin
from http.server import BaseHTTPRequestHandler, HTTPServer
class StoreHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        if self.path == "/store.json":
            with open(pjoin(curdir, 'store.json')) as fh:
                self.send_response(200)
                self.send_header('Content-type','text/json')
                self.end_headers()
                self.wfile.write(fh.read())
        elif self.path == "/Stock.htm":
            with open(pjoin(curdir, 'stock.htm')) as fh:
                self.send_response(200)
                self.send_header('Content-type','text/html')
                self.end_headers()
                self.wfile.write(fh.read())
        else:
            with open(pjoin(curdir, 'index.htm')) as fh:
                self.send_response(200)
                self.send_header('Content-type','text/html')
                self.end_headers()
                self.wfile.write(fh.read())
    def do_POST(self):
        if self.path == '/store.json':
            length = self.headers.getheader('content-length')
            data = self.rfile.read(int(length))
            with open(pjoin(curdir, 'store.json'), 'w') as fh:
                fh.write(data)
            self.send_response(200)

server = HTTPServer(('', 8080), StoreHandler)
server.serve_forever()

例外出力は次のとおりです。

127.0.0.1 - - [30/Oct/2012 16:48:17] "GET / HTTP/1.1" 200 -

更新:更新されたコードは次のようになります。

from os import curdir
from os.path import join as pjoin

from http.server import BaseHTTPRequestHandler, HTTPServer

class StoreHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        if self.path == "/store.json":
            with open(pjoin(curdir, 'store.json')) as fh:

                self.send_header('Content-type','text/json')
                self.end_headers()
                self.wfile.write(fh.read(), 'rb')

server = HTTPServer(('', 8080), StoreHandler)
server.serve_forever()

ソケットはバイトを送受信しますが、モードを指定せずにファイルを開いたので、Unicode 文字列を送信しようとしています (Python 3 では、すべての文字列がデフォルトで Unicode であることを思い出してください)。

次のいずれかを実行できます。

- また -

  • バイナリ モードでファイルを開きます - (追加のパラメーターに注意してください) に変更open(pjoin(curdir, 'a.file'))します。open(pjoin(curdir, 'store.json'), 'rb')rb
