Question

我无法下载以下url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();

Answer 1

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...

Sorry, your browser doesn't seem to support frames! <br>
Proceed to <A href="https://www.avisloyalty.eu/assets/fleetlarge//VW_Passat_15.jpg">https://www.avisloyalty.eu/assets/fleetlarge//VW_Passat_15.jpg</A> manually.

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什么的...
