Question

我正在使用像我这样的应用程序进行改造

  static void Main(string[] args)
    {
        double[] xVal = new double[9]
        {

    ...


           };
        double[] yVal = new double[9]  {
     ...

        };
        double rsquared;
        double yintercept;
        double slope;
        LinearRegression(xVal, yVal,0,9, out rsquared, out yintercept, out slope);
        Console.WriteLine( yintercept + (slope*15));//15 is xvalue of future(no of day from 1)

        Console.ReadKey();
    }
    public static void LinearRegression(double[] xVals, double[] yVals,
                                        int inclusiveStart, int exclusiveEnd,
                                        out double rsquared, out double yintercept,
                                        out double slope)
    {
        Debug.Assert(xVals.Length == yVals.Length);
        double sumOfX = 0;
        double sumOfY = 0;
        double sumOfXSq = 0;
        double sumOfYSq = 0;
        double ssX = 0;
        double ssY = 0;
        double sumCodeviates = 0;
        double sCo = 0;
        double count = exclusiveEnd - inclusiveStart;

        for (int ctr = inclusiveStart; ctr < exclusiveEnd; ctr++)
        {
            double x = xVals[ctr];
            double y = yVals[ctr];
            sumCodeviates += x * y;
            sumOfX += x;
            sumOfY += y;
            sumOfXSq += x * x;
            sumOfYSq += y * y;
        }
        ssX = sumOfXSq - ((sumOfX * sumOfX) / count);
        ssY = sumOfYSq - ((sumOfY * sumOfY) / count);
        double RNumerator = (count * sumCodeviates) - (sumOfX * sumOfY);
        double RDenom = (count * sumOfXSq - (sumOfX * sumOfX))
         * (count * sumOfYSq - (sumOfY * sumOfY));
        sCo = sumCodeviates - ((sumOfX * sumOfY) / count);

        double meanX = sumOfX / count;
        double meanY = sumOfY / count;
        double dblR = RNumerator / Math.Sqrt(RDenom);
        rsquared = dblR * dblR;
        yintercept = meanY - ((sCo / ssX) * meanX);
        slope = sCo / ssX;
    }

发送请求后我正在呼叫

 final OkHttpClient okHttpClient = new OkHttpClient();
 okHttpClient.interceptors().add(new YourInterceptor());

            final OkClient okClient = new OkClient(okHttpClient);
            Builder restAdapterBuilder = new RestAdapter.Builder();
            restAdapterBuilder.setClient(okClient).setLogLevel(LogLevel.FULL)
                    .setEndpoint("some url");
            final RestAdapter restAdapter = restAdapterBuilder.build();


public class YourInterceptor implements Interceptor {

    @Override
    public Response intercept(Chain chain) throws IOException {
        // TODO Auto-generated method stub
        Request request = chain.request();

        if (request != null) {
            Request.Builder signedRequestBuilder = request.newBuilder();
            signedRequestBuilder.tag("taggiventorequest");
            request = signedRequestBuilder.build();
            request.tag();
        }
        return chain.proceed(request);
    }
}

但是请求没有取消我收到了改造的回复不知道为什么它没有取消我的要求

我需要排球，比如取消改装

Answer 1

作为Retrofit API Spec，取消请求将包含在2.0版中。

取消（）是收到回复后的无操作。在所有其他在这种情况下，该方法会将任何回调设置为null（从而释放强大的如果匿名声明，则引用封闭类）请求对象死了。以后与请求的所有交互对象将抛出异常。如果请求在等待执行者将取消其未来，以便永远不会被调用。

现在，您可以通过创建自定义回调类来实现，该类在回调时通过回调实现。

public abstract class CancelableCallback<T> implements Callback<T> {

    private boolean canceled;
    private T pendingT;
    private Response pendingResponse;
    private RetrofitError pendingError;

    public CancelableCallback() {
        this.canceled = false;
    }

    public void cancel(boolean remove) {
        canceled = true;
    } 

    @Override
    public void success(T t, Response response) {
        if (canceled) {
            return;
        }
        onSuccess(t, response);
    }

    @Override
    public void failure(RetrofitError error) {
        if (canceled) {
            return;
        }
        onFailure(error);
    }

    protected abstract void onSuccess(T t, Response response);

    protected abstract void onFailure(RetrofitError error);
}

MyApi.java，

private interface MyApi {
    @GET("/")
    void getStringList(Callback<List<String>> callback);
}

在活动或片段中，

RestAdapter restAdapter = new RestAdapter.Builder()
            .setEndpoint(Config.URL)
            .build();
MyApi service = restAdapter.create(MyApi.class);
CancelableCallback callback = new CancelableCallback<List<String>>() {
    @Override
    protected void onSuccess(List<String> stringList, Response response) {
        for (String str : stringList) {
            Log.i("Result : ", str);
        }
    }

    @Override
    protected void onFailure(RetrofitError error) {
        Log.e("Error : ", error.getMessage() + "");
    }
};

service.getStringList(callback);

要取消您的请求，请致电

callback.cancel();

这是取消每个请求的简单示例。您可以通过创建回调管理器类来同时处理（取消，暂停，恢复）两个或多个请求。请查看that comment以供参考。

希望它对你有用。

Answer 2

问题是请求已完成，来自docs：

http://square.github.io/okhttp/javadoc/com/squareup/okhttp/OkHttpClient.html#cancel-java.lang.Object-

cancel
public OkHttpClient cancel（Object tag）

取消标记为tag的所有已安排或正在进行的呼叫。已完成的请求无法取消。

改造+ Okhttp取消操作不起作用
