graphhopper GHRequest不取

Question

我有這個代碼的問題：

GraphHopperAPI gh = new GraphHopperWeb(); 
    gh.load("http://localhost:8989/api/route"); 
    GHResponse ph = gh.route(new GHRequest(45.104546,7.69043,45.104546,7.69043)); 

它給我這個錯誤：

2014-03-29 09:33:00,036 [main] INFO graphhopper.http.GraphHopperWeb - Full request  took:0.037406, API took:0.0

文檔目前發生的變化（從維基移動它到源）。你在哪裏找到該片段？請嘗試gh.load("http://localhost:8989/");爲最新的分支和gh.load("http://localhost:8989/api");之前。
