android 中的 Reddit 整合

Question

我使用它的 API 实现了 reddit 集成。下面是我登录 reddit 的代码：

private void LoginMethod(){

        String jsonString = "";
        DefaultHttpClient httpclient = new DefaultHttpClient();

        final ArrayList<NameValuePair> fields = new ArrayList<NameValuePair>(3);
        fields.add(new BasicNameValuePair("user", "test"));//will ask for a user to enter the password later
        fields.add(new BasicNameValuePair("passwd", "test11"));
        fields.add(new BasicNameValuePair("api_type", "json"));

        final HttpPost request = new HttpPost("https://ssl.reddit.com/api/login");

        try {
            request.setEntity(new UrlEncodedFormEntity(fields, HTTP.UTF_8));

            HttpResponse response = httpclient.execute(request);
            HttpEntity entity = response.getEntity();

            jsonString = EntityUtils.toString(entity);

            System.out.println("response from redit = " + jsonString);

            JSONObject jObject = new JSONObject(jsonString);
            modhash = jObject.getJSONObject("json").getJSONObject("data").getString("modhash");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (JSONException e) {
            e.printStackTrace();
        }

}

使用上面的方法，它只是有时有效并且大部分得到如下响应：

我不知道如何处理这类问题。我已经对此进行了研发，但是没有太多的细节或示例可用于 reddit 集成。

所以，帮助解决这个错误。

Answer 1

来自 API 文档：

Make no more than thirty requests per minute

您超过了这个数字，因此您的请求被拒绝了。

https://github.com/reddit/reddit/wiki/API#rules

Answer 2

除了 Antonio MG 的回答之外，您还应该根据 reddit API rules:

设置自定义用户代理

"Many default User-Agents (like "Python/urllib" or "Java") are drastically limited to encourage unique and descriptive user-agent strings."

至少，它应该包括 reddit 工作人员的联系信息，以便在必要时取得联系。根据要求，它应该是以下形式：

<platform>:<app ID>:<version string> (by /u/<reddit username>)

例如

android:com.example.myredditapp:v1.2.3 (by /u/kemitche)

最后，您应该强烈考虑使用 OAuth 2 访问 reddit 的 API，而不是直接登录； "cookie" authentication is scheduled for deprecation.
