小编Gra*_*pes的帖子

在 redux 教程中，我们学习了如何执行乐观更新：

第 8 部分-rtk-query-advanced#implementing-optimistic-updates

但在updateQueryData的 API 参考中，我发现args必须传入 an ：

const updateQueryData = (
  endpointName: string,
  args: any,
  updateRecipe: (draft: Draft<CachedState>) => void
) => ThunkAction<PatchCollection, PartialState, any, AnyAction>;

所以，如果我们的帖子有分页，

getPosts: builder.query({
  query: (current: number) => `/posts?current=${current}`,
  providesTags: ['Post']
}),

这个时候我们如何进行乐观更新呢？

// Is there a way to update all getPosts caches?
// Am I missing some documents?
apiSlice.util.updateQueryData('getPosts', ???, (draft) => {
  const post = draft.find((post) => post.id === postId)
  if (post) {
    post.reactions[reaction]++
  }
})

This is the original string:

233<C:\Users\Grapes\Documents\title.png>233<C:\Users\Grapes\Documents\title.png>33

This is the replaced string I want: 233<1>233<2>33

I want to replace the file path in the string with the id I got after uploading to the server, but my program is in an infinite loop.

public void sendMessage(String msg) {
    new Thread(()-> {
        var pat = Pattern.compile("<(.*?[^\\\\])>");
        var matcher = pat.matcher(msg);
        int k = 0;
        while (matcher.find()) {
            matcher.replaceFirst("<" + k++ + ">"));
        }
        System.out.println(msg);
    }).start();
}
