transmit | 接口数据转换,接口转发工具

TCP/IP connections are designed to be long-lived streaming connections (built on top of the out-of-order, no-guarantee, packet-based IP protocol).

That means that is.read(bytes) does exactly what the spec says it will: It will wait until at least 1 byte is available, OR the 'end of stream' signal comes in. As long as neither occurs (no bytes arrive, but the stream isn't closed), it will dutifully block. Forever if it has to.

The solution is to either [A] pre-send the size of the file, and then adjust the loop to just exit once you've received that amount of bytes, or [B] to close the stream.

To close the stream, close the socket. It kinda sounds like you don't wanna do that (that you are multiplexing multiple things over the stream, i.e. that after transfering a file, you may then send other commands).

So, option A, that sounds better. However, option A has as a prerequisite that you know how many bytes are going to come out of inputStream. If it's a file, that's easy, just ask for its size. If it's streamed data, that would require that, on the 'upload code side', you first stream the whole thing into a file and only then stream it over the network which is unwieldy and potentially inefficient.

If you DO know the size, it would look something like (and I'm going to use newer APIs here, you're using some obsolete, 20 year old outdated stuff):

I'm struggling to understand how that code fits together, but this part strikes me as definitely wrong:

According to MSDN:Sample, Maybe you need to set a pin's signal state to indicate the data has been sent/received in your microcontroller program. More details reside in your serial communication transmission of data standard. And you should write code according to the result of WaitCommEvent(hCom, &dwEvtMask, &o); like the linked sample.

After posting here, I figured out how to fix it.

In the video_feed function, in the media_type parameter, it was just to put it in the same way as in the flask:

This part :

\"phone\": "+getPhoneNumber_str+",\n

needs to be :

\"phone\": \""+getPhoneNumber_str+"\",\n

You need to create escaped quotes between the variable for correct concatenation.

Try below code to initialise Host and a Port.

Host-:

There are two issues here.

First, what you're passing to the function isn't what it's expecting. &message has type char (*)[4096], i.e. a pointer to an array of size 4096 of char. The function meanwhile is expecting a char *[4096], i.e. an array of size 4096 of char *. This is a type mismatch.

The second is that on this line:

Thank you very much. I replaced the raspberry pie and it was solved. This code worked fine. I apologize to you for a fuss over.

All configurations seems good, however you have to upgrade explorer version to be compatible with hyperledger fabric version.

So please use v1.1.4 instead of v1.1.1

Also make sure that you have mounted crypto config correctly, try to access this path inside the container /tmp/crypto/peerOrganizations/acme.com/tlsca/tlsca.acme.com-cert.pem

Try to change tlsCACerts path to use peer tls ca.crt /tmp/crypto/peerOrganizations/acme.com/peers/peer1.acme.com/tls/ca.crt

You have mentioned that the same configurations works with hyperledger fabric v2, if you have tried it locally not on the same server so I please disable the firewall on the server and give it a try

To check if you can reach domain and port please try this

cat > /dev/tcp/peer1.acme.com/7051
