如何从 Facebook 视频 URL 中提取可用的视频分辨率？
How to extract available video resolutions from Facebook video URL?
在我的 Facebook Video Downloader android 应用程序中，我想显示 SD、HD 等视频分辨率和大小.目前我正在使用 InputStreamReader 和 Pattern.compile 方法来查找 SD 和 HD URL 的视频。
这种方法很少让我 HD link 的视频并且只提供 SD URL 可以下载。
下面是我link解析的代码
fun linkParsing(url: String, loaded: (item: DownloadItem) -> Unit) {
val showLogs: Boolean = true
Log.e("post_url", url)
return try {
val getUrl = URL(url)
val urlConnection =
getUrl.openConnection() as HttpURLConnection
var reader: BufferedReader? = null
urlConnection.setRequestProperty("User-Agent", POST_USER_AGENT)
urlConnection.setRequestProperty("Accept", "*/*")
val streamMap = StringBuilder()
try {
reader =
BufferedReader(InputStreamReader(urlConnection.inputStream))
var line: String?
while (reader.readLine().also {
line = it
} != null) {
streamMap.append(line)
}
} catch (E: Exception) {
E.printStackTrace()
reader?.close()
urlConnection.disconnect()
} finally {
reader?.close()
urlConnection.disconnect()
}
if (streamMap.toString().contains("You must log in to continue.")) {
} else {
val metaTAGTitle =
Pattern.compile("<meta property=\"og:title\"(.+?)\" />")
val metaTAGTitleMatcher = metaTAGTitle.matcher(streamMap)
val metaTAGDescription =
Pattern.compile("<meta property=\"og:description\"(.+?)\" />")
val metaTAGDescriptionMatcher =
metaTAGDescription.matcher(streamMap)
var authorName: String? = ""
var fileName: String? = ""
if (metaTAGTitleMatcher.find()) {
var author =
streamMap.substring(metaTAGTitleMatcher.start(), metaTAGTitleMatcher.end())
Log.e("Extractor", "AUTHOR :: $author")
author = author.replace("<meta property=\"og:title\" content=\"", "")
.replace("\" />", "")
authorName = author
} else {
authorName = "N/A"
}
if (metaTAGDescriptionMatcher.find()) {
var name = streamMap.substring(
metaTAGDescriptionMatcher.start(),
metaTAGDescriptionMatcher.end()
)
Log.e("Extractor", "FILENAME :: $name")
name = name.replace("<meta property=\"og:description\" content=\"", "")
.replace("\" />", "")
fileName = name
} else {
fileName = "N/A"
}
val sdVideo =
Pattern.compile("<meta property=\"og:video\"(.+?)\" />")
val sdVideoMatcher = sdVideo.matcher(streamMap)
val imagePattern =
Pattern.compile("<meta property=\"og:image\"(.+?)\" />")
val imageMatcher = imagePattern.matcher(streamMap)
val thumbnailPattern =
Pattern.compile("<img class=\"_3chq\" src=\"(.+?)\" />")
val thumbnailMatcher = thumbnailPattern.matcher(streamMap)
val hdVideo = Pattern.compile("(hd_src):\"(.+?)\"")
val hdVideoMatcher = hdVideo.matcher(streamMap)
val facebookFile = DownloadItem()
facebookFile?.author = authorName
facebookFile?.filename = fileName
facebookFile?.postLink = url
if (sdVideoMatcher.find()) {
var vUrl = sdVideoMatcher.group()
vUrl = vUrl.substring(8, vUrl.length - 1) //sd_scr: 8 char
facebookFile?.sdUrl = vUrl
facebookFile?.ext = "mp4"
var imageUrl = streamMap.substring(sdVideoMatcher.start(), sdVideoMatcher.end())
imageUrl = imageUrl.replace("<meta property=\"og:video\" content=\"", "")
.replace("\" />", "").replace("&", "&")
Log.e("Extractor", "FILENAME :: NULL")
Log.e("Extractor", "FILENAME :: $imageUrl")
facebookFile?.sdUrl = URLDecoder.decode(imageUrl, "UTF-8")
if (showLogs) {
Log.e("Extractor", "SD_URL :: Null")
Log.e("Extractor", "SD_URL :: $imageUrl")
}
if (thumbnailMatcher.find()) {
var thumbNailUrl =
streamMap.substring(thumbnailMatcher.start(), thumbnailMatcher.end())
thumbNailUrl = thumbNailUrl.replace("<img class=\"_3chq\" src=\"", "")
.replace("\" />", "").replace("&", "&")
Log.e("Extractor", "Thumbnail :: NULL")
Log.e("Extractor", "Thumbnail :: $thumbNailUrl")
facebookFile?.thumbNailUrl = URLDecoder.decode(thumbNailUrl, "UTF-8")
}
}
if (hdVideoMatcher.find()) {
var vUrl1 = hdVideoMatcher.group()
vUrl1 = vUrl1.substring(8, vUrl1.length - 1) //hd_scr: 8 char
facebookFile?.hdUrl = vUrl1
if (showLogs) {
Log.e("Extractor", "HD_URL :: Null")
Log.e("Extractor", "HD_URL :: $vUrl1")
}
} else {
facebookFile?.hdUrl = null
}
if (imageMatcher.find()) {
var imageUrl =
streamMap.substring(imageMatcher.start(), imageMatcher.end())
imageUrl = imageUrl.replace("<meta property=\"og:image\" content=\"", "")
.replace("\" />", "").replace("&", "&")
Log.e("Extractor", "FILENAME :: NULL")
Log.e("Extractor", "FILENAME :: $imageUrl")
facebookFile?.imageUrl = URLDecoder.decode(imageUrl, "UTF-8")
}
if (facebookFile?.sdUrl == null && facebookFile?.hdUrl == null) {
}
loaded(facebookFile!!)
}
} catch (e: Exception) {
e.printStackTrace()
}
}
我想实现一个功能，我可以显示不同的分辨率和尺寸，如图所示。
请注意，我已经用 HD URL 的视频测试了我的 linkParsing 方法，但它只提供 SD URL。
这是一个示例视频 link：https://fb.watch/aENyxV7gxs/
如何做到这一点？我无法为此找到任何合适的方法或 GitHub 库。
已找到解决方案，因此发布为答案。
这可以通过提取网页的 Page Source 然后解析该 XML 并获取 BASE URL 列表来完成。
步骤如下：
1- 在 Webview 中加载特定视频 URL 并在 onPageFinished
中获取页面源代码
private fun webViewSetupNotLoggedIn() {
webView?.settings?.javaScriptEnabled = true
webView?.settings?.userAgentString = AppConstants.USER_AGENT
webView?.settings?.useWideViewPort = true
webView?.settings?.loadWithOverviewMode = true
webView?.addJavascriptInterface(this, "mJava")
webView?.post {
run {
webView?.loadUrl(“url of your video")
}
}
object : WebViewClient() {
override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
if (url == "https://m.facebook.com/login.php" || url.contains("https://m.facebook.com/login.php")
) {
webView?.loadUrl("url of your video")
}
return true
}
override fun onPageStarted(view: WebView?, url: String?, favicon: Bitmap?) {

}
}
webView.webChromeClient = object : WebChromeClient() {
override fun onProgressChanged(view: WebView?, newProgress: Int) {
super.onProgressChanged(view, newProgress)
if (progressBarBottomSheet != null) {
if (newProgress == 100) {
progressBarBottomSheet.visibility = View.GONE
} else {
progressBarBottomSheet.visibility = View.VISIBLE
}
progressBarBottomSheet.progress = newProgress
}
}
}
webView?.webViewClient = object : WebViewClient() {
override fun onPageFinished(view: WebView?, url: String?) {
try {
if (webView?.progress == 100) {
var original = webView?.originalUrl
var post_link = "url of your video"
if (original.equals(post_link)) {
var listOfResolutions = arrayListOf<ResolutionDetail>()
val progressDialog = activity?.getProgressDialog(false)
progressDialog?.show()
//Fetch resoultions
webView.evaluateJavascript(
"(function(){return window.document.body.outerHTML})();"
) { value ->
val reader = JsonReader(StringReader(value))
reader.isLenient = true
try {
if (reader.peek() == JsonToken.STRING) {
