Volley 不会为我的自定义请求调用 getParams? [英] Volley does not call getParams for my custom request?

问题描述

请问，Volley 是否会自动将我的 GET 参数添加到 URL 中?对我来说，它不起作用，而且在查看来源时，我找不到任何 getParams 方法的调用..那么我应该自己构建 URL 吗?完全没问题，我只是想当有像getParams这样的方法时，它可以为我做到这一点:)

Please, does Volley automatically add my GET params to the URL? For me it's not working so and also when looking into sources, I just cant find any call of the getParams method.. So should I build the URL myself? It's no problem at all, I just thought that when there is such method like getParams, it could do that for me:)

更新:下面是我的代码..

UPDATE: Below is my code..

public class BundleRequest extends com.android.volley.Request<Bundle>{

    private String token;
    private OnAuthTokenValidatorResponseListener mListener;
    private final Map<String, String> mParams =  new HashMap<String, String>();;


    public BundleRequest(int method, String url,  Response.ErrorListener listener) {
        super(method, url, listener);
    }

    public BundleRequest(int method, String url,OnAuthTokenValidatorResponseListener providedListener,  Response.ErrorListener listener, String token) {
        super(method, url, listener);
        this.token = token;
        mListener = providedListener;
        mParams.put(AuthenticatorConfig.TOKEN_VALIDATION_PARAMNAME, token);

    }

    @Override
    public Map<String, String> getParams() throws AuthFailureError {
        return mParams;
    }




    @Override
    protected Response<Bundle> parseNetworkResponse(NetworkResponse httpResponse) {
        switch (httpResponse.statusCode) {
            case AuthTokenValidator.TOKEN_VALID_RESPONSE_CODE:
                //token is ok
                JSONObject response;
                try {
                        response = new JSONObject(new String(httpResponse.data, HttpHeaderParser.parseCharset(httpResponse.headers)));
                        Bundle userDataResponse = new Bundle();
                        userDataResponse.putInt("responseCode", httpResponse.statusCode);
                        userDataResponse.putString("username", response.getString("user_id"));
                        userDataResponse.putString("email", response.getString("user_email"));
                        userDataResponse.putString("expiresIn", response.getString("expires_in"));
                        userDataResponse.putString("scope", response.getJSONArray("scope").getString(0));
                        userDataResponse.putString("token", token);
                    return Response.success(userDataResponse, HttpHeaderParser.parseCacheHeaders(httpResponse));
                    } catch (UnsupportedEncodingException e) {
                        e.printStackTrace();
                    return Response.error(new VolleyError("Unsupported encoding"));


                } catch (JSONException e) {
                    e.printStackTrace();
                    return Response.error(new VolleyError("Problem while parsing JSON"));
                }




            case AuthTokenValidator.TOKEN_INVALID_RESPONSE_CODE:
                //token is not valid
                mListener.onValidatorResponse(httpResponse.statusCode);
                try {
                    mListener.onValidatorResponse(parseOnErrorResponse(new String(httpResponse.data, HttpHeaderParser.parseCharset(httpResponse.headers))));
                } catch (UnsupportedEncodingException e) {
                    e.printStackTrace();
                }

            default:
                return Response.error(new VolleyError("Error status code:" + httpResponse.statusCode));

        }
    }

    protected int parseOnErrorResponse(String responseBody) {
        try {
            JSONObject response = new JSONObject(responseBody);
            String moreInfo = response.getString("more_info");
            if (moreInfo.equals("Token was not recognised")) {
                return AuthTokenValidator.TOKEN_WAS_NOT_RECOGNISED;
            } else if (moreInfo.equals("Token has expired")) {
                return AuthTokenValidator.TOKEN_HAS_EXPIRED;
            } else if (moreInfo.equals("Client doesn't exist anymore")) {
                return AuthTokenValidator.CLIENT_DOES_NOT_EXIST_ANYMORE;
            } else if (moreInfo.equals("Client is locked")) {
                return AuthTokenValidator.CLIENT_IS_LOCKED;
            } else {
                return AuthTokenValidator.UNKNOWN_ERROR;
            }

        } catch (JSONException e) {
            e.printStackTrace();
            return AuthTokenValidator.UNKNOWN_ERROR;
        }

    }

    @Override
    protected void deliverResponse(Bundle response) {
        mListener.onGetUserDataResponse(response);
    }
}

实际上 params 参数现在是多余的

Actually the params parameter is now redundant

推荐答案

getParams() 未在 GET 方法上调用，因此您似乎必须先将其添加到 URL 中发送请求.

getParams() is not called on the GET method, so it seems you'll have to add it to the URL before you send the request.

查看 JavaDoc:

Check out the JavaDoc:

返回用于 POST 或 PUT 请求的参数映射.

Returns a Map of parameters to be used for a POST or PUT request.

可以抛出 {@link AuthFailureError} 因为可能需要身份验证提供这些值.

Can throw {@link AuthFailureError} as authentication may be required to provide these values.

请注意，您可以直接覆盖 {@link #getBody()} 进行自定义数据.

Note that you can directly override {@link #getBody()} for custom data.

@throws AuthFailureError 在身份验证失败的情况下

@throws AuthFailureError in the event of auth failure
