我有这段代码接受服务器响应并将其写入文件。
该文件包含 json 数据。我将响应写入文件以便按顺序扫描 json 并避免在列表中加载大的 json 数据!
我认为这种方法会引发异常,但我不确定!
public File getData(final String url) throws URISyntaxException, AuthenticationException, IOException, ClientProtocolException, HttpResponseException {
final HttpGet getRequest = new HttpGet(new URI(url));
final UsernamePasswordCredentials creds = new UsernamePasswordCredentials(username, password);
getRequest.addHeader(new BasicScheme().authenticate(creds, getRequest));
getRequest.setHeader("Content-Type", "application/json");
final ResponseHandler<byte[]> responseHandler = new ByteArrayResponseHandler();
final byte[] responseBody = mClient.execute(getRequest, responseHandler);
final File output = new File(FileConfig.TEMP_PATH + System.currentTimeMillis()+".json");
final FileOutputStream fos = new FileOutputStream(output.getPath());
fos.write(responseBody);
fos.close();
return output;
}
但我注意到最近(我不知道为什么)我得到了这个异常:

一切似乎都有效,但我对这个例外感到困惑。
targetSdk ok 我的应用程序是 13。
