QUESTION
I am trying to perform SMTP diagnostics using curl and am getting this error: "curl: (94) An authentication function returned an error". Googling this error doesn't return much other than the generic error list and descriptions.
I am using the curl client that comes with Git on Windows 10, and have tried running this from both Gitbash and the normal Command Line. The mail server is a corporate server at the overseas headquarters and we don't have easy access to the configuration or logs. It does require SSL/TLS for the connection.
I am able to successfully send an email using the Powershell script attached further below.
The curl error:
...ANSWER
Answered 2022-Mar-11 at 14:52I'm not familiar with the SMTP feature of curl, but I know quite a bit about SMTP. curl apparently failed to authenticate. I haven't found a documentation about which authentication mechanisms it supports, but GSSAPI doesn't seem to be one of them (at least not with the options that you specified). (I know nothing about GSSAPI either.)
My guess about what went wrong is that you're not using TLS with curl (STARTTLS is still listed as one of the supported extensions). What I take from this documentation is that you should either specify --ssl or --ssl-reqd, or change smtp to smtps (smtps://mymailserver.com), which switches from Explicit TLS to Implicit TLS. The list of supported authentication mechanisms often changes once TLS is enabled and will likely include PLAIN afterwards.

QUESTION
I'm a noob with Golang. I managed to get some things done with lots of effort. I'm dealing with JSON files containing dates in a nested way.
I came across some workaround to unmarshal dates from JSON data into time.Time but I'm having a hard time dealing with nested ones.
The following code (obtained here in StackOverflow) is easy to understand since creates a user-defined function to parse the time objects first to a string and then to time.Time with time.Parse.
ANSWER
Answered 2022-Mar-10 at 19:12To solve this using the patterns you've already got, you can write a separate unmarshalling function for the inner struct. You can do that by hoisting the inner struct to its own named struct, and then writing the function.
QUESTION
I'm using Go v1.17.3
I'm pretty new with Go and coming from an OOP background I'm very aware I'm not in the Gopher mindset yet! So I've split the question in 2 sections, the first is the problem I'm trying to solve, the second is what I've done so far. That way if I've approached the solution in a really strange way from what idiomatic Go should look like the problem should still be clear.
1. Problem I'm trying to solve:
Deserialise a JSON request to a struct where the struct name is specified in one of the fields on the request.
Example code
Request:

I am working on breaking the monolithic architecture into Microservice architecture. I did that but when I am building the code in my current repository I am getting this error.
We use graphql-gophers library
panic: too many parameters returned by (Resolver).Dummy
Has anyone ever seen this error in golang using graphql for querying?
Tried so many things but nothing has worked.
Any help would be appreciated
...ANSWER
Answered 2022-Jan-17 at 07:26The error message comes from graph-gophers/graphql-go internal/exec/resolvable/resolvable.go#makeFieldExec
It is called when you parse a schema which does not match the field of an existing struct.
The one illustrated in example/customerrors/starwars.go does match every field and would not trigger the error message:

QUESTION
I am a Gopher Noob. I ran into this question recently regarding implementing priority queues in Golang. I went through https://pkg.go.dev/container/heap@go1.17.3 for implementing a priority queue. All one has to do is implement the heap.Interface for the container. Its straightforward enough and i have no questions about that.
My question though is this: I need two priority queues. One is a minimum and maximum priority queue. In Java, this is quiet easy is initialize. I just have to change the comparator during initialization and thats it. In golang, I simply have to change the Less method in sort.Interface which is fine. However, I am not interested in writing redundant code and i am looking for cleaner way to create both priority queues.
Here is an example for what i am looking to do:
...ANSWER
Answered 2021-Nov-29 at 06:29You can inject the function as a dependency to the constructor for the Priority Queue struct.
It should work as follows:
