Google Drive Insert Permission

See more Google Drive Examples

This example demonstrates how to insert a permission for a file (see https://developers.google.com/drive/v2/reference/permissions/insert)

The impetus for creating this example was a need to be able to view files uploaded using a service account key in the Google Drive web interface. When using a service account access token, the files your application will see are those for the service account, and not the files for your main account. For example, the Google Account I use for testing has a username of "support@chilkatcloud.com". (Don't send email to support@chilkatcloud.com, it's just use for testing and not interactively read.) I use "support@chilkatcloud.com" when I log into Google interactively to view files in Google Drive at https://drive.google.com/drive/my-drive.

The files I upload to Google Drive using a service account key won't be visible in the browser UI. To make them visible, you need to insert a permission for the file so that the main user account, which in this case is "support@chilkatcloud.com", is a reader. After the permission is inserted, the file will be visible under "Shared with me" -- as if another Google Drive account shared the file with you.

Go
    success := false

    success = true

    // It requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // This example uses a previously obtained access token having permission for the 
    // Google Drive scope.

    gAuth := chilkat.NewAuthGoogle()
    gAuth.SetAccessToken("GOOGLE-DRIVE-ACCESS-TOKEN")

    rest := chilkat.NewRest()

    // Connect using TLS.
    bAutoReconnect := true
    success = rest.Connect("www.googleapis.com",443,true,bAutoReconnect)

    // Provide the authentication credentials (i.e. the access token)
    rest.SetAuthGoogle(gAuth)

    rest.AddHeader("Content-Type","application/json; charset=UTF-8")

    json := chilkat.NewJsonObject()
    json.AppendString("role","reader")
    json.AppendString("type","user")
    json.AppendString("value","support@chilkatcloud.com")

    // A note from a Chilkat customer:
    // 
    //   My coding attempt was frustrated because I tried a role of "owner".
    //   Even when providing the extra parameter of ...?transferOwnership=true
    //   that approach fails (400, Bad Request).
    // 

    // This example is inserting a permission for the file whose fileId is "0By-hrxCCDzSQUGxJY0hzNUFpNmc".
    jsonResponse := rest.FullRequestString("POST","/drive/v2/files/0By-hrxCCDzSQUGxJY0hzNUFpNmc/permissions",*json.Emit())
    if rest.LastMethodSuccess() != true {
        fmt.Println(rest.LastErrorText())
        gAuth.DisposeAuthGoogle()
        rest.DisposeRest()
        json.DisposeJsonObject()
        return
    }

    // A successful response will have a status code equal to 200.
    if rest.ResponseStatusCode() != 200 {
        fmt.Println("response status code = ", rest.ResponseStatusCode())
        fmt.Println("response status text = ", rest.ResponseStatusText())
        fmt.Println("response header: ", rest.ResponseHeader())
        fmt.Println("response JSON: ", *jsonResponse)
        gAuth.DisposeAuthGoogle()
        rest.DisposeRest()
        json.DisposeJsonObject()
        return
    }

    // Show the JSON response.
    json.Load(*jsonResponse)

    // Show the full JSON response.
    json.SetEmitCompact(false)
