Question

我在Android中使用Google API V2。如果我想获得从pointA到pointB的路由，但我想通过pointC和pointD，Google says来表示请求应该是：

http://maps.googleapis.com/maps/api/directions/json?origin=pointA&destination=pointB&waypoints=pointC|pointD

然而，我收到此错误：

Caused by: java.lang.IllegalArgumentException: Illegal character in query at index 191: blablabla (it is because | character)
        at java.net.URI.create(URI.java:727)
        at org.apache.http.client.methods.HttpPost.<init>(HttpPost.java:79)
        at mcd0n3ld.roadcheckpoints.ToolsMap$JSONParser.getJSONFromUrl(ToolsMap.java:216)
        [some more but not interesting...]

有关如何解决此问题的任何想法？

您需要使用URL Encoder

对参数进行编码

String params = "pointC|pointD";
try {
     params = URLEncoder.encode(params, "UTF-8");
} catch (UnsupportedEncodingException e1) {
    // TODO Auto-generated catch block
     e1.printStackTrace();
}

然后concat

String url = "http://maps.googleapis.com/maps/api/directions/json?origin=pointA&destination=pointB&waypoints="+params;
