Android:如何使用Retrofit获取会话id？

implementation 'com.squareup.retrofit2:retrofit:2.x.x'

public interface ApiService {
    @GET("get_session_id")
    Call<String> getSessionId();
}

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("https://api.example.com/") // 替换为实际的API地址
        .addConverterFactory(GsonConverterFactory.create())
        .build();

ApiService apiService = retrofit.create(ApiService.class);

Call<String> call = apiService.getSessionId();
call.enqueue(new Callback<String>() {
    @Override
    public void onResponse(Call<String> call, Response<String> response) {
        if (response.isSuccessful()) {
            String sessionId = response.body();
            // 在这里处理会话id
        } else {
            // 请求失败，处理错误信息
        }
    }

    @Override
    public void onFailure(Call<String> call, Throwable t) {
        // 请求失败，处理错误信息
    }
});
