java - 如何从Java代码调用couchDB View ？

Question

我从我的java代码中调用couchDB View ，代码如下。

我将 CouchDB View URL 传递给 HttpGet() 方法并能够获取数据。

    HttpGet get = new HttpGet("http://localhost:5984/tp/_design/tp/_view/tp?startkey=1388607960000");

        HttpResponse response = httpclient.execute(get);

        HttpEntity entity=response.getEntity();

        InputStream instream = entity.getContent();

        BufferedReader reader = new BufferedReader(new InputStreamReader(instream));

        String strdata = null;

        String jsonString = "" ;

        while( (strdata =reader.readLine())!=null)
        {
            jsonString += strdata;
        }

但现在要求发生了变化，希望再向 View URL 传递一个参数，如下所示:

   http://localhost:5984/tp/_design/tp/_view/tp?startkey=1388607960000&endkey={}

此处 endkey 确实包含任何数据，但必须将 endkey 值作为 {} 传递。当我传递 endkey={} 时，出现如下错误:

   Exception in thread "main" java.lang.IllegalArgumentException: Illegal character in query at index 97: http://localhost:5984/tp/_design/tp/_view/tp?startkey=1388607960000&endkey={}

    Caused by: java.net.URISyntaxException: Illegal character in query at index 97:

谁能帮我解决这个错误？？？

感谢您的回复...我没有将参数与 URL 一起传递，而是按照下面的方式进行操作，现在可以正常工作了。

    HttpGet get = new HttpGet("http://localhost:5984/tp/_design/tp/_view/tp?startkey=1388607960000");
    HttpParams params=new BasicHttpParams();
    System.out.println(epoch);
    params.setParameter("endkey", "{}");
    get.setParams(params);
