如何通过Dropbox获取fileList？

Question

我有个问题。但是我的英语说得不好。请理解。

我从Dropbox得到了access token。我想要一份文件清单。

我找不到Dropbox核心API。请告诉我们如何得到一个文件列表。

======================================================================

gpgekko//我被告知必须找到元数据没有期望的结果。

此URL用于导入元数据。

https://api.dropbox.com/1/metadata/<root>/<path>

/<root>/<path>排除不知道它是什么。

JSP文件，此函数被调用。

public void getFiles() throws IOException {
    consoleCheck("getFiles");

    String parameters = "access_token=" + access_token;
    parameters += "&redirect_uri=" + redirect_uri;
    parameters += "&list=true";
    URL url = new URL("https://api.dropbox.com/1/metadata/");
    URLConnection conn = url.openConnection();
    conn.setDoOutput(true);

    DataOutputStream writer = new DataOutputStream(conn.getOutputStream());
    writer.writeBytes(parameters);
    writer.flush();

    if (writer != null)
        writer.close();

    InputStream inputStream = conn.getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
    String line;
    StringBuffer stringBuffer = new StringBuffer();

    while ((line = reader.readLine()) != null) {
        stringBuffer.append(line);
        stringBuffer.append('\r');
    }
    JSONObject object = (JSONObject) JSONValue.parse(stringBuffer.toString());
    System.out.println("object => " + object);
}

就这样解决了。

我删除参数中的redirect_uri，并在url末尾添加/dropbox/。

public JSONObject getFiles() throws IOException {
    consoleCheck("getFiles");

    String parameters = "access_token=" + access_token;
    //parameters += "&redirect_uri=" + redirect_uri;
    parameters += "&list=true";
    URL url = new URL("https://api.dropbox.com/1/metadata/dropbox/");
    URLConnection conn = url.openConnection();
    conn.setDoOutput(true);

    DataOutputStream writer = new DataOutputStream(conn.getOutputStream());
    writer.writeBytes(parameters);
    writer.flush();

    if (writer != null)
        writer.close();

    InputStream inputStream = conn.getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
    String line;
    StringBuffer stringBuffer = new StringBuffer();

    while ((line = reader.readLine()) != null) {
        stringBuffer.append(line);
        stringBuffer.append('\r');
    }
    JSONObject object = (JSONObject) JSONValue.parse(stringBuffer.toString());
    //System.out.println("object => " + object);
    return object;
}

结果类型为JSONObejct。结果值是这样的。

{
"size": "0 bytes",
"hash": "37eb1ba1849d4b0fb0b28caf7ef3af52",
"bytes": 0,

        "mime_type": "text/plain",
        "revision": 220191
    }
],
"revision": 29007
}

谢谢大家。

将您的问题标记为"java“之后，我建议您尝试遵循他们的教程这里。特别是当列出文件夹时-他们使用DbxClient.getMetadataWithChildren()。
