okhttp3为空响应>> [

Question

所以我将此类编码为Download URLs，但它返回Null响应我尝试调试，但一无所知

package com.example.instaup;
import org.jetbrains.annotations.NotNull;
import java.io.IOException;
import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class Downloader
{
    private String myResponse;

    public String DownloadText(String url)
    {
            OkHttpClient client = new OkHttpClient();
            Request request = new Request.Builder()
                    .url(url)
                    .build();
            client.newCall(request).enqueue(new Callback() {
                @Override
                public void onFailure(@NotNull Call call, @NotNull IOException e) {
                    e.printStackTrace();
                }
                @Override
                public void onResponse(@NotNull Call call, @NotNull Response response) throws IOException {
                    if (response.isSuccessful()) {
                        myResponse = response.body().toString();
                    }
                }
            });
        return myResponse;
    }
}

有人可以帮我吗？我对此很陌生

所以我将此类编码为Download URLs，但它返回Null响应，我尝试调试但不了解com.example.instaup包；导入org.jetbrains.annotations.NotNull;导入...

您应该重用客户端，并使用同步形式execute而不是几乎在请求完成之前返回的入队回调API。
