如何在 Android 上使用 Volley 的基本身份验证? [英] How does one use Basic Authentication with Volley on Android?

问题描述

我正在查看示例和代码，但没有看到任何实现.在这个阶段这可能吗?

I'm looking through examples and code but I don't see anything implemented. Is this possible at this stage?

推荐答案

是的，这是可能的.您需要覆盖 Request.getHeaders().我很懒惰，我使用了 Spring for Android 的 HttpHeaders 和 HttpAuthentication，但您可以只构建 auth 标头并从方法中返回它.从 getHeaders() 您可以返回基本身份验证的身份验证标头.这是具有基本身份验证的示例请求.

Yes it's possible. You need to override Request.getHeaders(). I'm lazy and I used HttpHeaders and HttpAuthentication from Spring for Android but you can just build the auth header and return it from the method. From getHeaders() you can return the auth header for basic auth. This is a sample request with basic auth.

public class GetUser extends Request<User> {

    private static final String TAG = GetUser.class.getName();

    private Response.Listener<User> mListener;
    private ObjectMapper mMapper = new ObjectMapper();

    public GetUser(Response.ErrorListener errorListener, Response.Listener<User> listener){
        super(Method.GET, PoisUtils.BASE_URL + "/users", errorListener);

        mListener = listener;
    }

    @Override
    protected Response<User> parseNetworkResponse(NetworkResponse response) {
        String jsonString = new String(response.data);
        try {
            User result = mMapper.readValue(jsonString, User.class);
            return Response.success(result, getCacheEntry());
        } catch (IOException e) {
            Log.d(TAG, e.getMessage());
        }
        return null;
    }

    @Override
    protected void deliverResponse(User response) {
        mListener.onResponse(response);
    }

    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        return AuthUtils.buildAuthHeaders().toSingleValueMap();
    }
}

这是我构建身份验证标头的方法

And here is how I build the auth headers

public static HttpHeaders buildAuthHeaders(){

    if(UserUtils.isUserLogged()){
        HttpHeaders requestHeaders = new HttpHeaders();
        User user = PoisApplication.get().getUser();

        HttpAuthentication auth = new HttpBasicAuthentication(
                user.getUsername(), user.getPassword());
        requestHeaders.setAuthorization(auth);

        return requestHeaders;
    }
    return null;
}
