根据索引合并clojure中地图的两个向量

我在 clojure 中有两个地图向量，我希望将它们合并，使其成为单个地图向量，但每个索引处的地图都被合并。我只是想知道做到这一点的最佳方法。

例如：

[{:sku "e1" :name "example1"} {:sku "e2" :name "example2"}]
[{:color "Blue" :price 9.99} {:color "Red" :price 15.99}]

将合并到：

[{:sku "e1" :name "example1" :color "Blue" :price 9.99} {:sku "e2" :name "example2" :color "Red" :price 15.99}]

原文

I have two vectors of maps in clojure, and I wish to merge them so that it is a single vector of maps, but the maps at each index are merged. I was just wondering the best way to do this.

For example:

[{:sku "e1" :name "example1"} {:sku "e2" :name "example2"}]
[{:color "Blue" :price 9.99} {:color "Red" :price 15.99}]

Would be merged to:

[{:sku "e1" :name "example1" :color "Blue" :price 9.99} {:sku "e2" :name "example2" :color "Red" :price 15.99}]

使用 mapv 和 合并：

(mapv merge 
      [{:sku "e1" :name "example1"} {:sku "e2" :name "example2"}]
      [{:color "Blue" :price 9.99} {:color "Red" :price 15.99}])

=> [{:sku "e1", :name "example1", :color "Blue", :price 9.99} {:sku "e2", :name "example2", :color "Red", :price 15.99}]

Use mapv and merge:

(mapv merge 
      [{:sku "e1" :name "example1"} {:sku "e2" :name "example2"}]
      [{:color "Blue" :price 9.99} {:color "Red" :price 15.99}])

=> [{:sku "e1", :name "example1", :color "Blue", :price 9.99} {:sku "e2", :name "example2", :color "Red", :price 15.99}]
