示例
代码编辑器 (JavaScript)
// A FeatureCollection with an array property value.
var fc = ee.FeatureCollection([]).set('array_property', ee.Array([1, 2, 3, 4]));
// Fetch the array property value as an ee.Array object.
print('Array property value as ee.Array', fc.getArray('array_property'));

Colab (Python)
# A FeatureCollection with an array property value.
fc = ee.FeatureCollection([]).set('array_property', ee.Array([1, 2, 3, 4]))
# Fetch the array property value as an ee.Array object.
print('Array property value as ee.Array:',
fc.getArray('array_property').getInfo())
