[GitHub] [rocketmq-client-python] zhxsxuan opened a new issue #87: producer can't send byte string of an image file
zhxsxuan opened a new issue #87:
URL: https://github.com/apache/rocketmq-client-python/issues/87
I tried to send sync a byte string read from an image to RMQ by the following code:
```
with open("model/test.jpeg", "rb") as f:
img_str = f.read()
msg.set_body(img_str)
ret = producer.send_sync(msg)
```
but the message body a consumer received is only a part of the byte string
```
b'\xff\xd8\xff\xdb'
```

I tried changing the set_body function as following
```
def set_body(self, body):
if isinstance(body, binary_type):
ffi_check(dll.SetByteMessageBody(self._handle, _to_bytes(body), len(body)))
ffi_check(dll.SetMessageBody(self._handle, _to_bytes(body)))
```
But the message received was not changed.

the py SDK does not support the binary message body.
maybe you can encode the byte body using base64 encoding before sending and decode it before consuming.
another way, you can try to add a new API to set a binary message body using a special C API "SetByteMessageBody" instead.
