I need to send data of nested JSON object from gRPC-web to Backend Golang server. I ended up with converting and sending JSON as a string to the backend server and converting the string back to the JSON in the backend server. Is this a good practice or is there any other solution to transfer JSON.

I'm looking at a request, sending some json to a spring mvc app (v4). The request is sent with a Content-Type: application/json header.
On the server side, the request handler is set with automatic serialization, through a #RequestBody annotation.
Everything's peachy right until I add a backslash to one of the variables in the payload. Then the server throws a 400 bad request.
I'd like to:
keep the request payload as json
not resort to manual encoding/decoding
How to fix this?
Thanks!
Sorted.
Problem was on the client side: client code was writing-out a json string, instead of JSON.stringify()ing an object. Once that is fixed, JSON.stringify() presents the backslash correctly to the server (backslash is reserved in json for escaping).
I am using httpClient.addInterceptor(logging); to log every requests made before it is being sent to the server.
But, I have to use those requests to be saved as a string for my generous purpose. If it is possible than how can I implement it?
I tried the SignalR(Self-Host) and seems it wraps the message with its own payload in JSON.
Is it able to handle SignalR raw message?
I wanna set the WebSocket sub-protocol to "wamp"
I need send & receive the message in raw format as it is on client side
I don't need any fallback support, only WebSocket and I wanna turn off all the other fallback features

As far as I know, SignalR does not support WebSocket sub-protocols, It can handle strings if you use the PersistentConnection API, that contains a method to receive String :
Task OnReceived(IRequest request, string connectionId, string data);
If you need WebSockets with a custom protocol, you can use XSocket.NET : https://github.com/XSockets
I am a student who just started using Netty!
I am building a server that communicates with android and iOS. The primary task of my server will be sending and recieving JSON files with images(10 jpegs) and texts(less than 100 character).
My server's framework is Netty.
I built my server from "HttpUploadServer" from the Netty 4.0.6 example jar. As my server's primary task is to upload and download JSON files, I only used multipart POST part from the example.
So here is my question.
Netty's HttpRequestEncoder and HttpResponseDecoder turns Http requests into ByteBuf and ByteBuf to responses.
However, what happens when I try to communicate with JSON? Does the encoder and decoder turn JSON into a ByteBuf and sends it?
What is the normal way Netty users send and recieve JSON through HTTP?
For sending and receiving JSON messages, you don't need to add any Handlers. Http Encoders/Decoders are enough.
Here is a example that uses JSON to send and receive.

What is the difference between the Response object and Request object in ASP?
Generally, the request object is going to hold information about the current user request, that is the client browser requesting a webpage from your server. The response object contains the response data that will be sent back to the user. Think of it in terms of a http request/response cycle. The objects hold the respective data.
The ASP Request object is used to get information from a visitor.
Usually, you read the contents of the request to determine the course of action and the proper response.
The ASP Response object is used to send output to the user from the server.
Request Object: is used to read the data submitted by the client (i.e. the data comes with the client request)
Response Object: is used to send instructions to the client browser.
This might help you further.
Request object: from client (you) to server.
Response object: from Server to client (you) rendering back to the service.
These objects are called intrinsic object of ASP.Net.
Request Object:
Used to send information to the clients.
Response Object:
Used to retrieve information included with the request from server.
