TypeError: 'bytearray' object cannot be interpreted as an integer

Question

我想通过 HTTP 发送音频数据，但我不明白为什么会出现此异常：

Exception happened during processing of request from ('127.0.0.1', 59976)
Traceback (most recent call last):
  File "/usr/lib/python3.6/socketserver.py", line 654, in process_request_thread
    self.finish_request(request, client_address)
  File "/usr/lib/python3.6/socketserver.py", line 364, in finish_request
    self.RequestHandlerClass(request, client_address, self)
  File "/usr/lib/python3.6/socketserver.py", line 724, in __init__
    self.handle()
  File "/usr/lib/python3.6/http/server.py", line 418, in handle
    self.handle_one_request()
  File "/usr/lib/python3.6/http/server.py", line 406, in handle_one_request
    method()
  File "/home/vivanov/temp.py", line 113, in do_GET
    data.append(bytearray(stream.read(CHUNK)))
TypeError: 'bytearray' object cannot be interpreted as an integer

问题似乎与将值传递给 wfile.write 有关。

我该如何解决这个问题？

这是我的代码：

class ChunkingRequestHandler(BaseHTTPRequestHandler):
    ALWAYS_SEND_SOME = False
    ALLOW_GZIP = False
    protocol_version = 'HTTP/1.1'
    def do_GET(self):
        ae = self.headers.get('accept-encoding') or ''

        # send some headers
        self.send_response(200)
        self.send_header('Transfer-Encoding', 'chunked')
        self.send_header('Content-type', 'audio/x-wav')

        self.end_headers()

        data = bytearray(wav_header)
        data.append(bytearray(stream.read(CHUNK)))
        print(data)
        self.wfile.write(b"%X\r\n%s\r\n" % (len(data), data))

        while True:
            data = bytearray(stream.read(CHUNK))
            self.wfile.write(b"%X\r\n%s\r\n" % (len(data), data))

        # send the chunked trailer
        self.wfile.write('0\r\n\r\n')

Answer 1

尽管名称如此，但如果您想一次将多个元素附加到 Python 中的类列表对象，则不能使用 append 方法。 bytearray 就像一个字节列表，因此将另一个 bytearray 附加或连接到它的方法是使用 extend 方法，或 +=:

data += bytearray(...)
#  OR
data.extend(bytearray(...))

事实上，如果您要添加到 bytearray 的内容已经可以传递给 bytearray() 构造函数，则您可能不需要将其包装在 bytearray()。例如bytes个对象（如b'something'）可以直接添加：

data += b'something'

一旦你修复了那行代码，你可能会在其他行上遇到问题。例如，如果 wfile.write 采用 bytes，那么向它发送一个像 '0\r\n\r\n' 这样的 unicode 字符串可能会出错；看起来你打算写 b'0\r\n\r\n'.

Answer 2

实际上这是我最终工作的最终代码，可能对某人有用：

class ChunkingRequestHandler(BaseHTTPRequestHandler):
    ALWAYS_SEND_SOME = False
    ALLOW_GZIP = False
    protocol_version = 'HTTP/1.1'
    def do_GET(self):
        ae = self.headers.get('accept-encoding') or ''

        # send some headers
        self.send_response(200)
        self.send_header('Content-type', 'audio/x-wav')

        self.end_headers()

        data = []
        for i in wav_header:
            data.append(int(i))
        for i in stream.read(CHUNK):
            data.append(int(i))
        self.wfile.write(bytearray(data))

        while True:
            data = []
            for i in stream.read(CHUNK):
                data.append(int(i))
            self.wfile.write(bytearray(data))

        # send the chunked trailer
        self.wfile.write('0\r\n\r\n')
