Question

我一直在尝试使用Foursquare API构建Android应用。我希望我的用户是匿名的，这样就不会有身份验证。如上所述here：

 As covered in our platform docs, our Venues Platform endpoints can be accessed without  
 user authentication and our Merchant Platform endpoints require the end-user to be an  
 authed venue manager. All other endpoints, unless otherwise noted, require user  
 authentication.

我发现Venue类别（“https://api.foursquare.com/v2/venues/categories”）是Venues Platform端点，因此我获取了这样的类别：

    private static final String API_URL = "https://api.foursquare.com/v2";
    private static final String VENUE_CATEGORY = "/venues/categories";

                URL url = new URL(API_URL + VENUE_CATEGORY);

                Log.d(TAG, "Opening URL " + url.toString());

                HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

                urlConnection.setDoInput(true);
                urlConnection.setDoOutput(true);

                urlConnection.connect();

                String response     = streamToString(urlConnection.getInputStream());
                JSONObject jsonObj  = (JSONObject) new JSONTokener(response).nextValue();

                JSONObject resp     = (JSONObject) jsonObj.get("response");
                JSONArray category  =  resp.getJSONArray("categories");

                JSONObject sample   = category.getJSONObject(0);
                mCategoryName       = sample.getString("name");

我得到java.io.FileNotFoundException:https://api.foursquare.com/v2/venues/categories 我还是首先需要在这里获取访问令牌吗？

您是对的，您无需身份验证即可访问venues/categories端点，但为了实现此目的，您需要提供客户端ID和客户端密钥作为API调用的参数，以便Foursquare知道它是您的应用访问端点。

您可以注册一个应用程序来获取客户端ID和密钥here（如果您还没有），那么如果您将详细信息添加到网址，您应该能够访问该端点：

private static final String API_URL = "https://api.foursquare.com/v2";
private static final String VENUE_CATEGORY = "/venues/categories";
private static final String CLIENT_INFO = "client_id=YOURCLIENTID&client_secret=YOURCLIENTSECRET"

URL url = new URL(API_URL + VENUE_CATEGORY + "?" + CLIENT_INFO);

希望有所帮助。
