"attempted read from closed str" 的意思是“尝试从已关闭的字符串中读取”。这通常是因为程序员在使用字符串时没有正确地关闭它,导致在后续的读取操作中出现错误。解决方法是在使用完字符串后及时关闭它,或者在读取之前检查字符串是否已经关闭。

I'm sorry, I'm not sure what you mean by "Attempted read from closed stream." Could you please provide more context or information about what you are experiencing?
org.apache.http.HttpResponse 获取entry Attempted read from closed stream
当使用`org.apache.http.HttpResponse`对象的`getEntity().getContent()`方法获取返回的响应内容时,如果该响应内容的流已经被关闭,再次尝试读取流中的数据就会抛出"Attempted read from closed stream"异常。
解决这个问题的方法是,在读取完响应内容后,手动关闭响应内容的流。代码示例:
```
HttpResponse response = httpClient.execute(httpPost);
HttpEntity entity = response.getEntity();
InputStream inputStream = entity.getContent();
try {
// 读取流中的数据
} finally {
inputStream.close();
}
```
这样,在`finally`块中关闭流,即使在读取过程中抛出了异常,也能保证流被正确关闭,避免了"Attempted read from closed stream"异常的发生。
