Google地图编码折线未按预期显示

本文介绍了Google地图编码折线未按预期显示的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我试图创建一个加拿大所有省份的编码折线。我开始使用这个工具：





但是当我将多段线插入到代码中进行映射时，它会给我提供部分不同的行：



任何想法为什么线偏离？我尝试了两次，每次中途换行。



谢谢

解决方案

您需要转义字符串中的\字符（用双\\替换单个\）。

更改：

I'm trying to create an encoded polyline of all Canadian provinces. I begun with this utility:

https://developers.google.com/maps/documentation/utilities/polylineutility

Using it I create many point to follow the province line of ontario as closely as possible. Here's a screenshot of the resulting polyline:

but when I take the polyline an plug it into the code to map it, It provides me with partially different line:

Any Ideas why the line deviates? I tried it twice, each time the line veers of midway.

Thanks

解决方案

You need to escape the "\" characters in the string (replace the single "\" with a double "\\").
