在Android中，您可以使用org.apache.http类HttpClient、HttpGet和HttpResponse下载文件。如何从HTTP请求中读取建议的文件名？
例如，在PHP中，您可以这样做：
header('Content-Disposition: attachment; filename=blah.txt');
如何使用Android/Java中的Apache类获取"blah.txt"？
BasicHeader header = new BasicHeader("Content-Disposition", "attachment; filename=blah.txt");
HeaderElement[] helelms = header.getElements();
if (helelms.length > 0) {
HeaderElement helem = helelms[0];
if (helem.getName().equalsIgnoreCase("attachment")) {
NameValuePair nmv = helem.getParameterByName("filename");
if (nmv != null) {
System.out.println(nmv.getValue());
}
}
}
sysout>blah.txt
HttpResponse response = null;
try {
response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
//observe all headers by this
Header[] h = response.getAllHeaders();
for (int i = 0; i < h.length; i++) {
System.out.println(h[i].getName() + " " + h[i].getValue());
}
//choose one header by giving it's name
Header header = response.getFirstHeader("Content-Disposition");
String s = header.getValue()
