我試圖使用DownloadManager從服務器上下載文件,但它沒有下載並說下載失敗,我讀過下載管理器存在問題在下面的鏈接 android-chrome-browser-unnecessarily-renames-names-types-of-downloaded-files所以我試圖通過使用下面的方法添加RequestHeader到DownloadManagerRequest下載文件,但沒有發生任何事情。請找到我的Downloader類的下面的代碼部分任何人請建議我使用DownloadManager從url下載文件的正確方法。下載使用DownLoadManager.Request從URL下載文件時失敗

由於
public void download(Uri uri) {
if (!isDownloading()) {
String fileName=getName(uri);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setTitle(fileName);
request.setNotificationVisibility(1);
request.allowScanningByMediaScanner();
request.addRequestHeader("Content-Type", "application/octet-stream");
request.addRequestHeader("Content-Disposition", "attachment; filename=\""+fileName.split("\\.")[0]+"."+fileName.split("\\.")[1].toUpperCase()+"\"");
String cookieContent = getCookieFromAppCookieManager(uri.getHost());
request.addRequestHeader("Cookie", cookieContent);
downloadId = downloadManager.enqueue(request);
register();
}
}
和下面的框返回的文件名
private String getName(Uri uri) {
String name=uri.toString().split("jabord/")[1].split("\\?")[0];
return name;
}
返回appcookie經理
public String getCookieFromAppCookieManager(String url){
android.webkit.CookieManager cookieManager = android.webkit.CookieManager.getInstance();
if (cookieManager == null) {
return null;
}
String rawCookieHeader = null;
// Extract Set-Cookie header value from Android app CookieManager for this URL
rawCookieHeader = cookieManager.getCookie(url);
if (rawCookieHeader == null) {
return null;
}
return rawCookieHeader;
};
