Firebase响应400

Question

我有以下基础结构：

现在我想向文章节点添加一些数据。例如：

{"title":"Test","content":"Test text","keyWords":"1,2,3","date":"Aug 14, 2015 5:52:16 PM"}

Firebse REST API文档说，我应该POST数据，但是日志写入

  

服务器返回HTTP响应代码：400为URL：   HTTPS：？//$TEST-BASE.firebaseio.com/articles.json AUTH = $ TOKEN

$TEST-BASE和$TOKEN是有效参数。我可以清楚地看到GET响应。怎么了？代码： 公共类JSONTest {

    public static void main(String[] args) throws IOException {
        post("{\"title\":\"Test\",\"content\":\"Test text\",\"keyWords\":\"1,2,3\",\"date\":\"Aug 14, 2015 5:52:16 PM\"}", "https://<TEST-BASE>.firebaseio.com/articles.json?auth=<TOKEN>");


    }

    private static void post(String json, String urlString) {     

        OutputStreamWriter out = null;
        try {
            URL url = new URL(urlString);
            HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
            httpCon.setDoOutput(true);
            httpCon.setRequestMethod("POST");
            out = new OutputStreamWriter(
                    httpCon.getOutputStream());
            System.out.println(json);
            out.write(json);
            httpCon.getInputStream();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (out != null) {
                try {
                    out.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

    }


}

我希望我有足够的声望点才能留下评论= P，但我相信你获得400的原因是因为你没有将你的数据发送到正确的终点。尝试从网址中删除.json：

https://<TEST-BASE>.firebaseio.com/articles?auth=<TOKEN>
