I am using ' The PacketBuffer class' to generate the json, and send it to the server.
Now my server is a nodejs based solution, but the problem is the json that pakcetbuffer class generated can not be parsed by the nodejs server, always throwing out a wrongsyntaxexception: unexpected token
for example:
packet.reset();
packet.print("{a:"); packet.print(66);
packet.print(",b:"); packet.print(77);
packet.print("}\0");
Seial.println(packet.buf); // it prints out {a:66,b:77}, but a correct json format should be {"a","66","b":"77"},
ether.browseUrl(PSTR("/test?apikey="APIKEY"&data="), packet.buf, NULL, callback);
the nodejs based server will throw out a wrongsyntaxexception: unexpected token a
I am so confused 'cause this example is similar to all the examples in github of open energy monitoring, such as the https://github.com/nathanchantrell/NanodeRF_emoncms/blob/master/NanodeRF_emoncms.ino. but this doesn't work for my nodejs based server
confused , how should I do to print a json to a nodejs based server?
Re: The PacketBuffer can't generate correct json for my nodejs based server
Then I tried
packet.reset();
packet.print("{\"a\":\""); packet.print(66);
packet.print("\",\"b\":\""); packet.print(77);
packet.print("\"}\0");
When I Serial.println(packet.buf); // it outputs {"a","66","b":"77"}, which is what I expected
but still on the nodejs based server, it throws out a error saying wrongsyntaxexception: unexpected end of input.
i can't figure out what is wrong with the end of input.
I replace \0 with \n or \r, neither of them works
