To make a

toSession

request with a JWT token in Go for a self-hosted Kratos, you can use the Ory Kratos Go SDK. Here is an example of how to do it:

go package main      import (    "context"    "fmt"    "os"       client "<http://github.com/ory/kratos-client-go|github.com/ory/kratos-client-go>"   )      func main() {    configuration := client.NewConfiguration()    configuration.Servers = []client.ServerConfiguration{     {      URL: "<http://127.0.0.1:4433>", // Kratos Public API     },    }    apiClient := client.NewAPIClient(configuration)    cookie := "ory_kratos_session=MTY0ODgyMTExN3xEdi1CQkFFQ180SUFBUkFCRUFBQVJfLUNBQUVHYzNSeWFXNW5EQThBRFhObGMzTnBiMjVmZEc5clpXNEdjM1J5YVc1bkRDSUFJRkZDVFVKbFNIcEJOalZyY0Vad1JEZ3dNMng1V0RsWlpEQlFXa3RoUjNJenzKCLhzCkox1OmvNJlKcqtWuNkSnPLrUgM6Ew2EMYksfg=="    resp, r, err := apiClient.FrontendApi.ToSession(context.Background()).Cookie(cookie).Execute()    if err != nil {     fmt.Fprintf(os.Stderr, "Error when calling `FrontendApi.ToSession``: %v\n", err)     fmt.Fprintf(os.Stderr, "Full HTTP response: %v\n", r)    }    // response from `ToSession`: Session    fmt.Fprintf(os.Stdout, "Traits  %v\n", resp.Identity.Traits)   }

In this example, the

cookie

variable should contain your JWT token. The

ToSession

method is called with the

cookie

as a parameter. If the request is successful, the response will contain the session information. Please note that the URL in the

configuration.Servers

should be the URL of your Kratos Public API. For more information, you can refer to the [Ory Kratos Go SDK documentation](https://www.ory.sh/docs/kratos/self-hosted/go).
