java - 查询时出现非法字符

Question

我有一个应用程序需要向 Google 查询方向等。我最近重新组织了我的代码，做了一些优化来查询带有路点的路线，以减少请求发送计数。现在有一个问题:我得到了

java.lang.IllegalArgumentException: Illegal character in query at index 146: http://maps.googleapis.com/maps/api/directions/json?origin=52.4000826,16.8928842&destination=52.4129715,16.8296386&waypoints=52.4053469,16.8969666|52.4049754,16.8811389&sensor=false

我认为索引 146 处的字符是“|”。这个角色有什么问题吗？

感谢您的建议。

这是我用于构建查询的代码:

try {
            String requestString = "http://maps.googleapis.com/maps/api/directions/"
                    + "json?origin="
                    + Double.toString(start.getLatitude())
                    + ","
                    + Double.toString(start.getLongitude())
                    + "&destination="
                    + Double.toString(end.getLatitude())
                    + "," + Double.toString(end.getLongitude());

            if (points.length > 2) {
                String waypoints = "&waypoints="
                        + Double.toString(points[1].getLatitude()) + ","
                        + Double.toString(points[1].getLongitude());
                for (int i = 2; i < points.length - 1; i++) {
                    waypoints = waypoints + "|"
                            + Double.toString(points[i].getLatitude())
                            + ","
                            + Double.toString(points[i].getLongitude());
                }
                requestString = requestString + waypoints;
            }
            requestString = requestString + "&sensor=false";

UFL1138 是对的。替换“|”与“%7C”有效。谢谢
