如何下载的Htt presponse到一个文件？ [英] How to download an HttpResponse into a file?

问题描述

我的Andr​​oid应用程序使用它发送一个多HTTP请求的API。我成功地得到像这样的回应：

My android app uses an API which sends a multipart HTTP request. I am successfully getting the response like so:

post.setEntity(multipartEntity.build());
HttpResponse response = client.execute(post);

的响应是一个电子书文件（通常是EPUB或牧高笛）的内容。我想写这与指定的路径下的文件，可以说/sdcard/test.epub。

The response is the contents of an ebook file (usually an epub or mobi). I want to write this to a file with a specified path, lets says "/sdcard/test.epub".

文件可达到20MB，所以需要使用某种流，但我就是不能换我的头周围。谢谢！

File could be up to 20MB, so it'll need to use some sort of stream, but I can just can't wrap my head around it. Thanks!

推荐答案

以及它是一个简单的任务，你需要的 WRITE_EXTERNAL_STORAG​​E 使用许可..然后只检索的InputStream

well it is a simple task, you need the WRITE_EXTERNAL_STORAGE use permission.. then simply retrieve the InputStream

InputStream is = response.getEntity().getContent();

创建一个FileOutputStream

Create a FileOutputStream

的FileOutputStream FOS =新的FileOutputStream（新文件（Environment.getExternalStorageDirectory（），test.epub））;

和读出是与FOS写

int read = 0;
byte[] buffer = new byte[32768];
while( (read = is.read(buffer)) > 0) {
  fos.write(buffer, 0, read);
}

fos.close();
is.close();
