要实现自动更新AccessToken并在屏幕上显示更新请求的响应数据,你可以使用以下步骤:
AccessTokenManager
的类,用于处理AccessToken的更新逻辑。该类应包含以下方法:public class AccessTokenManager {
private static final String TAG = "AccessTokenManager";
private static final String ACCESS_TOKEN_URL = "https://example.com/updateAccessToken"; // 替换为你的更新AccessToken的API URL
public interface OnAccessTokenUpdateListener {
void onAccessTokenUpdated(String newAccessToken);
void onAccessTokenUpdateFailed(String errorMessage);
}
public static void updateAccessToken(final OnAccessTokenUpdateListener listener) {
// 使用OkHttp或其他网络库发送HTTP请求
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(ACCESS_TOKEN_URL)
.build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
Log.e(TAG, "Failed to update access token: " + e.getMessage());
listener.onAccessTokenUpdateFailed(e.getMessage());
}
@Override
public void onResponse(Call call, Response response) throws IOException {
String responseBody = response.body().string();
Log.d(TAG, "Access token updated: " + responseBody);
listener.onAccessTokenUpdated(responseBody);
}
});
}
}
AccessTokenManager
类的updateAccessToken
方法,并实现OnAccessTokenUpdateListener
接口来处理更新后的AccessToken和错误情况。例如:public class MainActivity extends AppCompatActivity implements AccessTokenManager.OnAccessTokenUpdateListener {
private TextView responseTextView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
responseTextView = findViewById(R.id.responseTextView);
// 调用AccessTokenManager来更新AccessToken
AccessTokenManager.updateAccessToken(this);
}
@Override
public void onAccessTokenUpdated(String newAccessToken) {
// 更新UI以显示新的AccessToken
runOnUiThread(new Runnable() {
@Override
public void run() {
responseTextView.setText("Access token updated: " + newAccessToken);
}
});
}
@Override
public void onAccessTokenUpdateFailed(String errorMessage) {
// 更新UI以显示错误消息
runOnUiThread(new Runnable() {
@Override
public void run() {
responseTextView.setText("Failed to update access token: " + errorMessage);
}
});
}
}
activity_main.xml
)中添加一个TextView来显示更新请求的响应数据。例如:
这样,当你的应用启动时,它将自动更新AccessToken并在屏幕上显示更新请求的响应数据。
