如何使用Go API客户端以编程方式创建Google Cloud Function

Question

There is a Go package for interacting with the Cloud Functions API (google.golang.org/api/cloudfunctions/v1) but I can't figure out how to use it to create new functions. I'm getting 404 and 403 errors when attempting to upload to the signed URL for the Cloud Storage bucket.

Does anyone know how to use this package to deploy Cloud Functions?

I have encountered a similar issue when using google.golang.org/api/cloudfunctions/v1, the first problem with 403 error I had, was due to using auth client with presigned Generate Upload URL, using bare http client helped

httpClient := http.DefaultClient
data, err := ioutil.ReadAll(reader)
if err != nil {
    return err
}
request, err := http.NewRequest("PUT", uploadURL, bytes.NewReader(data))
if err != nil {
    return err
}
request.Header.Set("content-type", "application/zip")
request.Header.Set("x-goog-content-length-range", "0,104857600")
request.Header.Set("Content-Length", fmt.Sprintf("%d", len(data)))
response, err := httpClient.Do(request)
if err != nil {
    return err
}

Another issue I saw with 404 was when I was using location as region as opposed to the fully qualified name presented in the below snippet

var location =  'projects/${projectID}/locations/${region}'  
projectService := cloudfunctions.NewProjectsLocationsFunctionsService(ctxClient.service)
createCall := projectService.Create(location, request.CloudFunction)
createCall.Context(ctxClient.Context())
return createCall.Do()
