本文介绍了如何在Java中使用HttpClient检索二进制文件?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
目前,我可以按如下方式检索文本页面
At the moment I can retrieve a text page as follows
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(
"http://google.com");
try {
HttpResponse response = client.execute(get);
BufferedReader rd = new BufferedReader(new InputStreamReader(
response.getEntity().getContent()));
String line = "";
while ((line = rd.readLine()) != null) {
System.out.println(line);
}
} catch (IOException e) {
e.printStackTrace();
}
假设get以二进制文件为目标.如何将其正确保存到磁盘?
Suppose get is targeted at a binary file. How would I save this correctly to disk?
推荐答案
只是不要通过Reader
-从InputStream
读取数据并写入OutputStream
.
Just don't go via a Reader
- read the data from the InputStream
and write to an OutputStream
.
// Using Guava (guava-libraries.googlecode.com)
InputStream data = response.getEntity().getContent();
try {
OutputStream output = new FileOutputStream(filename);
try {
ByteStreams.copy(data, output);
} finally {
Closeables.closeQuietly(output);
}
} finally {
}
