google-maps - 带有编码折线的 Google Static Maps API

Question

我已向谷歌路线 API 提出请求并收到以下 JSON 路线:

在底部，我得到了编码的折线数据:

现在理论上我应该能够在 map 上显示这条路线，就像..

但是，唉，这不起作用，有人对为什么有任何想法吗？这应该是一个相当基本的练习。因为它只是使用谷歌自己的 API。

Answer 1

似乎折线概述使用了很多导致问题的“\\”，所以我用“\”替换了“\\”的所有实例。

在字符串上使用 python 替换对其进行排序。

string_new = string.replace("\\\\", "\\")
