Golang：在json.Decode / Unmarshal之后的profiler中有很多堆项

Question

我有一个golang脚本示例：它获取页面响应并将其作为goroutine的不定式循环中的主体解组。

#   0x6b7699    compress/flate.NewReader+0x49           /usr/local/go/src/compress/flate/inflate.go:828

#   0x4012f9    main.main.func1+0x29                /root/test.go:30

但是当我打开探查器时，堆项的数量正在增加 时间。 堆项的示例：

难道你不能解释，问题是什么？无论如何，谢谢你
