我无法下载以下网址中的文件:http://avisloyalty.eu/assets/fleetlarge//VW_Passat_15.jpg
只下载了文件的一部分。
以下是我的代码。如果我做错了什么，请告诉我。
URLConnection urlConn = new URL( "http://avisloyalty.eu/assets/fleetlarge//VW_Passat_15.jpg").openConnection();
InputStream is = urlConn.getInputStream();
FileOutputStream fos = new FileOutputStream( file.getPath() );
byte[] buffer = new byte[4096];
int len;
while( ( len = is.read( buffer ) ) > 0 )
{
fos.write( buffer, 0, len );
}
fos.close();
最佳答案
我刚试过这个...
HttpClient client = HttpClientBuilder.create().build();
HttpGet get = new HttpGet("http://avisloyalty.eu/assets/fleetlarge//VW_Passat_15.jpg");
HttpResponse execution = client.execute(get);
HttpEntity entity = execution.getEntity();
FileOutputStream outputStream = new FileOutputStream("C:\\tmp\\imgout.jpg");
if (entity != null) {
InputStream inputStream = entity.getContent();
IOUtils.copy(inputStream, outputStream);
}
outputStream.close();
...并且输出文件包含 TEXT...

所以您的代码可能没有问题(不过我仍然会使用 != -1 而不是 > 0)!也许你需要设置一个请求头或其他东西......
