Android 在onErrorResponse方法中处理BasicNetwork.performRequest

我正在使用安卓截击库。我得到以下错误

BasicNetwork.performRequest:意外响应代码404

我如何处理这个错误？请给我一个解决方案

代码：

私有void insertRegistration（最终字符串userId、最终字符串密码、最终字符串mobileNo）{ showProgressDialog（）

StringRequest putRequest=新的StringRequest（Request.Method.POST，Constants.REGISTRATION\u URL，
新的Response.Listener（）
{
@凌驾
公共void onResponse（字符串响应）{
//回应
Log.d（“响应：：”，响应）；
if（response！=null&&response.length（）>3）{
如果（SharedReferencesHelper.getUser（context）.length（）>5）{
hideProgressDialog（）；
Toast.makeText（上下文，“成功注册”，Toast.LENGTH_LONG.show（）；
registrationActivity.this.finish（）；
}否则{
hideProgressDialog（）；
Toast.makeText（上下文，“注册失败”，Toast.LENGTH_LONG.show（）；
}
}
}, 
新的Response.ErrorListener（）
{
@凌驾
公共无效onErrorResponse（截击错误）{
hideProgressDialog（）；
}
}
) {
@凌驾
受保护的映射getParams（）
{       
Map params=newhashmap（）；
参数put（“empid”，userId）；
参数put（“通过”，密码）；
参数put（“移动”，mobileNo）；
返回参数；
}
};
//将请求添加到请求队列
Log.d（“putRequest:：”，“”+putRequest）；
AppController.getInstance（）.addToRequestQueue（putRequest，tag_reg_obj）；
}

我想基于异常分析错误

再看看这节课的截击：

/**
 * Data and headers returned from {@link Network#performRequest(Request)}.
 */
public class NetworkResponse {
    /**
     * Creates a new network response.
     * @param statusCode the HTTP status code
     * @param data Response body
     * @param headers Headers returned with this response, or null for none
     * @param notModified True if the server returned a 304 and the data was already in cache
     */
    public NetworkResponse(int statusCode, byte[] data, Map<String, String> headers,
            boolean notModified) {
        this.statusCode = statusCode;
        this.data = data;
        this.headers = headers;
        this.notModified = notModified;
    }

    public NetworkResponse(byte[] data) {
        this(HttpStatus.SC_OK, data, Collections.<String, String>emptyMap(), false);
    }

    public NetworkResponse(byte[] data, Map<String, String> headers) {
        this(HttpStatus.SC_OK, data, headers, false);
    }

    /** The HTTP status code. */
    public final int statusCode;

    /** Raw data from this response. */
    public final byte[] data;

    /** Response headers. */
    public final Map<String, String> headers;

    /** True if the server returned a 304 (Not Modified). */
    public final boolean notModified;
}

当异常发生时，我总是获取状态代码-1。我以这种方式解析截击错误，并得到了预期的结果。

@Override
        public void onErrorResponse(VolleyError error) {                    
              Log.d("Error.Response",  error.getMessage());  



           if (error instanceof NoConnectionError) {
                         Log.d("NoConnectionError>>>>>>>>>", "NoConnectionError.......");
                            ErrorMessage.logErrorMessage(getString(R.string.connection_error_msg), context);
           } else if (error instanceof AuthFailureError) {
                             Log.d("AuthFailureError>>>>>>>>>", "AuthFailureError.......");
                             ErrorMessage.logErrorMessage(getString(R.string.authFailure_error_msg), context);
            } else if (error instanceof ServerError) {
                             Log.d("ServerError>>>>>>>>>", "ServerError.......");
                             ErrorMessage.logErrorMessage(getString(R.string.server_connection_error_msg), context);
            } else if (error instanceof NetworkError) {
                             Log.d("NetworkError>>>>>>>>>", "NetworkError.......");
                             ErrorMessage.logErrorMessage(getString(R.string.network_error_msg), context);
                        } else if (error instanceof ParseError) {
                             Log.d("ParseError>>>>>>>>>", "ParseError.......");
                             ErrorMessage.logErrorMessage(getString(R.string.parse_error_msg), context);
           }else if (error instanceof TimeoutError) {
                             Log.d("TimeoutError>>>>>>>>>", "TimeoutError.......");
                             ErrorMessage.logErrorMessage(getString(R.string.timeout_error_msg), context);
           }
               }

没有评论。为什么我得到-1。我搜索了两天来寻找我的解决方案，但失败了。没有处理基本网络404错误的具体解决方案是的。我知道URL无效。我想测试和处理该URL无效，我想用“OneErrorResponse”来处理。因此，我如何处理不同类型的错误。我不明白您想要什么，是否要显示从服务器返回的错误消息？我想根据exceptionstatusCode=Error.networkResponse.statusCode；statusCode ia始终为0来分析错误。但NetworkError的错误实例是一种解决方案。我解决了这样的问题那样。

    /**

    public NetworkResponse(int statusCode, byte[] data, Map<String, String> headers,
            boolean notModified) {
        this.statusCode = statusCode;
        this.data = data;
        this.headers = headers;
