gorilla | web toolkit for the Go programming language

I have a restful API utilizing mux and mongo-driver. Following a tutorial, I attempted to setup the server and mongo client like so in the main package:

I am deploying an API made using Go and MySQl for the database to Heroku. I am following this guide on it and set up everything but now I am trying to execute a MySQL script to set up the tables with some dummy data. But I am constantly getting errors saying that the script is wrong even though I have used it locally with no issues. I have already connected the MySQL database to the Heroku environment and starting the database throws no errors.

Here are the logs showing the error when deploying it to Heroku:

I'm encountering what probably seems to be a Gopls language server issue: All my external package import statements are being marked as incorrect when using Go Modules with the Go extension in VSCode. Here's exactly what I did so far:

Inside my GOPATH/src/github.com/Kozie1337/projectname:

• run go mod init github.com/Kozie1337/projectname
• run go get -u github.com/gorilla/mux

Inside go.main:

Problem description:

I am learning Golang to implement the REST API for a small project. I was following this small example to get the some idea how to connect things. However, it looks like there are some bugs in the sample example, that i could not get the expected response in postman after hitting the endpoints. I have fixed it by adding the missing functions (HandleFunc functions) to make it work.

Problem Description:

However, I still have an issue with CreateEvent section. The expectation is that after using POST method with a given sample Event (json format) like below, event list is updated.

I'm trying to convert a list of tuples into a dictionary-dictionary format, however, i could only get a dictionary-list format. May i know how am i able to do it. Thanks in advance.

That is my server.go file where I define my server struct and its methods.

Below code is a websocket broadcast server that read from a specific connection then broadcasting it to connected clients.

But this server does not broadcast despite there is no error and warnings. Why this server does not broadcast?

In this code self.KabucomConn is origin socket so read from this socket, then broadcast to client which stored in Hub.RClients.

When new connection established, passing connection object with register channel to Hub, then Hub adds a client to RClient that stored client object.

I wrote a simple API with the Gorilla Web Toolkit, handling the CORS answers through its handlers:

I'm trying to extract a value from an HTTP POST request body (in my simple Go HTTP server) using the net/http PostFormValue and my output is an empty string when I'm looking for the any key in general, but in my case trying to fetch the hub.secret for use in a HMAC check. I use Postman to send the request to my localhost:8080 instance using the Gorilla/mux router, with header Content-Type: application/x-www-form-urlencoded set.

My handler looks like so:
