我在esp32板上有一个micropython客户端，在linux服务器上有一个python。我正在尝试将5.5kb文本文件从Python服务器发送到MicroPython客户端。它发送成功，但MicroPython客户端没有接收所有数据。代码如下;
蟒蛇服务器：
with open('downloads/%s' % (request_path), 'rb') as f:
data = f.read()
self.wfile.write(data) #data is 5.5kb
微蟒客户端
recvData = sock.read(4096).decode('utf-8').split("rn")
print("Response_Received:: %s" % recvData)
sock.close()

由于缓冲区大小(4096(，客户端仅接收4140字节的数组数据，recvData的第4个元素丢失。MicroPython 不接受超过此缓冲区大小。如何在 recvData 数组的第 4 个元素中接收所有数据 (5.5kb( 而不会丢失？
我试图对收到的数据进行碎片化，但没有成功。
while True:
chunck = s.recv(4096)
if not chunck:
break
fragments.append(chunck)
由于您的目标是将文件写入文件系统，因此最简单的解决方案是停止尝试将整个文件保存在内存中。 无需构建fragments数组，只需将收到的块写入文件：
with open('datafile', 'w') as fd:
while True:
chunk = s.recv(4096)
if not chunk:
break
fd.write(chunk)
这需要恒定的内存量，可用于接收 任意大小的文件。
