How to append text to a file in golang?
问题
我发现os.Open()返回一个O_RDONLY文件，os.Create()返回一个O_RDWR文件，但找不到一个方法返回一个APPEND文件指针。
有什么帮助吗？

The OpenFile takes a flags argument that you can use:
os.OpenFile("foo.txt", os.O_RDWR|os.O_APPEND, 0660);
Used with O_CREATE , OpenFile can also serve the same purpose as os.Create()
