whether vscode can change the mechanism that make me can get all all completionitem list include vscode itself provided in the following method provideCompletionItems in my vscode plugin? where I can know how vscode deal with this in vscode source?

vscode.languages.registerCompletionItemProvider("javascript",
{
    resolveCompletionItem(item:vscode.CompletionItem, token: vscode.CancellationToken): vscode.CompletionItem 
    {
    var completionItem1:vscode.CompletionItem = new vscode.CompletionItem("id");
    completionItem1.detail = "aaa";
    completionItem1.filterText = "aa";
    completionItem1.insertText = "aa";
    return completionItem1;
    }
    ,
    provideCompletionItems(document: vscode.TextDocument, position: vscode.Position, token: vscode.CancellationToken): Promise<vscode.CompletionItem[]> 
    {
        return new Promise((resolve, reject) => { 
        var completionItems:vscode.CompletionItem[] = [];

        return resolve(completionItems) ;
                    });
    }
})

Yes but with care only. With the Dec15 update you can invoke this command https://github.com/Microsoft/vscode/blob/master/src/vs/workbench/api/common/extHostLanguageFeatureCommands.ts#L55 to retrieve the same list of completions the UI would show. Note, that it will recurse into your provideCompletionItems call so that you must guard yourself to not recurse endless.
