java - 从 Google 云端硬盘获取可流式链接 [代码已准备就绪，访问被拒绝]

Question

我正在尝试重复从 Google Drive 获取可下载链接的过程，就像在 Internet Download Manager (Windows) 中使用的那样。

我正在做以下事情:

1. 下载链接的 HTML 源代码。
2. 使用正则表达式搜索 fmt_stream_map .
3. 解码。
4. 正在尝试访问链接。
5. 访问被拒绝。

互联网下载管理器使用了相同的方法，而且效果很好。我正在使用我的手机获取链接，并通过我的手机访问它。所以基本上它是相同的 IP 和相同的设备。

我的代码首先下载源代码。搜索 map 列表，然后将质量及其描述存储在数组中。之后，我搜索 fmt_stream_map 的链接，并将它们添加到最终的 model 中。 , 以便轻松访问它们。

我有 3 个类，其中两个是模型，最后一个是这个过程的主要类。

public class ItemStreamList {

    private String quality;
    private String description;

    public ItemStreamList(){

    }

    public ItemStreamList(String quality, String description){
        this.quality = quality;
        this.description = description;
    }

    public String getQuality() {
        return quality;
    }

    public void setQuality(String quality) {
        this.quality = quality;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }
}





public class ItemLink {

    private String quality;
    private String qualityDesc;
    private String link;

    public ItemLink(){

    }

    public ItemLink(String quality, String qualityDesc, String link){
        this.quality = quality;
        this.qualityDesc = qualityDesc;
        this.link = link;
    }

    public String getQualityDesc() {
        return qualityDesc;
    }

    public void setQualityDesc(String qualityDesc) {
        this.qualityDesc = qualityDesc;
    }

    public String getLink() {
        return link;
    }

    public void setLink(String link) {
        this.link = link;
    }

    public String getQuality() {
        return quality;
    }

    public void setQuality(String quality) {
        this.quality = quality;
    }
}

现在我们来到主类。这是一个“位”记录。

  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        getPageHTML("https://drive.google.com/file/d/0B7--EhvK76QDNmduLWFZMXh1dGs/view");
    }

    private void getPageHTML(final String mURL){
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    Document mDoc = Jsoup.connect(mURL).get();
                    String mHTML = mDoc.toString();

                    boolean hasSetStreamMapList = setStreamMapList(mHTML);

                    String mStreamMap = getMatchRegex(mHTML,"\"fmt_stream_map\",\"","\"]");
                    mStreamMap = org.apache.commons.text.StringEscapeUtils.unescapeJava(mStreamMap);
                    String[] mStreamMapQualities = mStreamMap.split(",");

                    if(hasSetStreamMapList){
                        List<ItemLink> mLinks = new ArrayList<>();

                        for (int i = 0; i < mStreamMapQualities.length; i++){
                            String[] mLinksArray = mStreamMapQualities[i].split("\\|");
                            String mLink = mLinksArray[1];
                            mLink = mLink.replaceAll("%2",",");
                            mLinks.add(new ItemLink(mLinksArray[0],getQualityDescription(mLinksArray[0]),mLink));
                        }

                        for (int i = 0; i < mLinks.size(); i++){
                            Log.i("StreamMap","Quality: " + mLinks.get(i).getQuality() + " - " + mLinks.get(i).getQualityDesc() + "\n" + "Link: " + mLinks.get(i).getLink());
                            Log.i("StreamMap","---------------------------");
                        }

                        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(mLinks.get(0).getLink())));


                    } else {
                        Log.i("StreamMap","Stream Map is NOT set");
                    }

                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }).start();
    }

    private List<ItemStreamList> mStreamListItems;

    private String getQualityDescription(String mQuality){

        for (int i = 0; i < mStreamListItems.size(); i++){

            if(mStreamListItems.get(i).getQuality().contains(mQuality))
                return mStreamListItems.get(i).getDescription();

Answer 1

您得到一个 403 代码，因为您没有在 fmt_stream_map 链接上的请求中传递任何 header 。

在浏览器中打开顶部链接时，将使用所有这些 header 查询 fmt_stream_map 链接:

所需的 header 未记录，因为您不应该以这种方式集成 google drive
