第二次打到API的流錯誤意外結束

Question

我正在嘗試Okhttp3庫，我對它很陌生。我讀了一些教程，它的工作正常，直到這個用例彈出：

我有一個外部Asynctask類，我正在執行我的POST和GET代碼。所以當我第一次打電話給Asynctask時，它工作正常。第二次我打電話給相同的Asynctask它給我的錯誤java.io.IOException：在okhttp3.Address上流的意外結束.....

有人可以請解釋爲什麼會發生這種情況？我在活動中創建OkHttpClient對象並將其傳遞給Asynctask。

這是構造：

public Post(JsonObject jsonParams){ 
this.jsonParams = jsonParams; 
} 

這是後臺任務：

Response response = null; 
    try { 
     OkHttpClient client = new OkHttpClient.Builder() 
       .retryOnConnectionFailure(true) 
       .build(); 

     RequestBody body = RequestBody.create(JSON, jsonParams); 
     Request.Builder requestBuilder = new Request.Builder() 
       .url(url) 
       .post(body) 
       .addHeader(APP_AUTHORIZATION_KEY, AUTHORIZATION_KEY); 

     Request request = requestBuilder.build(); 

     response = client.newCall(request).execute(); 
     if (response.isSuccessful()) { 
      responseBody = response.body().string(); 
      Log.v("POST RESPONSE", "response" + responseBody); 
     } 
    } catch (Exception ex) { 
     ex.printStackTrace(); 
    } finally { 
     if (response != null) 
      response.close(); 
    } 

我張貼我的日誌：

Answer 1

試試這個

OkHttpClient client = new OkHttpClient.Builder() 
    .retryOnConnectionFailure(true) 
    .build(); 


    try { 
     if (response.isSuccessful()) 
       responseBody = response.body().string(); 
     } finally { 
     response.close(); 
     }
