Python + Mysql：將geojson多邊形值插入到mysql sptial列中

Question

我有一個包含多邊形數據的geojson文件。下面是它的例子。

[[[127.00733253963132, 37.583203339216226],

我在MySQL中有空間表。我試圖使用row sql將這個多邊形數據插入多邊形列，但是，保持失敗。後來，我發現插入到mysql db中的多邊形數據看起來與我所擁有的有點不同。這是我從互聯網教程中看到的數據。

所以我的想法是把多邊形數據轉換爲字符串，並使用正則表達式替換括號。但是這種方法會花費很多時間。所以，我想知道是否有任何解決方案將這些數據插入到mysql多邊形字段中。

如果您使用的是PostgreSQL和PostGIS，則可以使用GeoAlchemy2庫。但我認爲目前不支持MySQL，如果我錯了，有人糾正我。
