Question

我有一个问题。但我不会说英语。请理解。

我从Dropbox获得了access token。我想要一个文件列表。

我找不到Dropbox Core API。请告诉我们如何获取文件列表。

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

gpgekko //我被告知你必须找到没有所需结果的元数据。

此网址用于导入元数据。

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

/<root>/<path>排除不知道它是什么。

JSP文件，调用此函数。

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);
}

将您的问题标记为“java”后，我建议您尝试按照他们的教程here进行操作。特别是当列出文件夹时 - 他们使用DbxClient.getMetadataWithChildren()。

Answer 2

以这种方式解决。

我删除参数中的redirect_uri并在网址末尾添加/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;
}

结果类型是JSONObejct。结果值就是这样。

    }
],
"revision": 29007
}

谢谢大家。
