在Android上一个人如何使用基本身份验证与排球？ [英] How does one use Basic Authentication with Volley on Android?

问题描述

我期待通过实例和code，但我没有看到任何实施。这是可能在这个阶段？

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，它是可能的。你需要重写Request.getHeaders（）。我很懒，我用HttpHeaders和HttpAuthentication从春季为Android，但你可以建立权威性的头，并从方法返回。从getHeaders（），您可以返回的基本身份验证的身份验证头。这是基本的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();
    }
}

这是我建立在auth头

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;
}
