当我使用原点，目的地和航点运行第一个Google API网址时，它会返回
{
"geocoded_waypoints" : [
{},
{},
{
"geocoder_status" : "ZERO_RESULTS"
}
],
"routes" : [],
"status" : "NOT_FOUND"
}
但是当我运行第二个网址时，这非常合适。

比较两个网址时有什么区别，我似乎无法找到任何网址。请帮忙！ 我试图通过航路点在起点和终点之间绘制路线。我怎么能实现这个？ 谢谢！
答案 0 :(得分：1)
检查您的目的地Latlng。您要求从斯里兰卡到尼日利亚（ 6.053518500000001,6.05351850000000 ）导航的第一个链接。我认为你正在添加不匹配目的地，即你也使用相同的经度纬度值。检查你的代码。
