Question

我从我的java代码调用couchDB视图，代码如下所示。

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;
        }

但是现在需求已经改变了想要将更多参数传递给View URL，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值传递为{}。当我通过endkey={}然后收到如下错误时：

   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:

任何人都可以帮我修复错误???

感谢您的回复...我没有将参数与URL一起传递，而是如下所示，现在正在运行。

    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);

建议你使用像jcouchDB这样的库，Jcouchdb提供了许多不同的使用java类的方法！CouchDB文档http://code.google.com/p/jcouchdb/wiki/Tutorial
