Question

Angular Material文档应用程序中的

https://docs.scipy.org/doc/scipy-0.14.0/reference/generated/scipy.optimize.fmin_tnc.html声明其模块如下：

@zip.command(aliases=['sd'])
@commands.has_role('Mods')
async def shutdown(ctx):
    await ctx.message.delete()
    intro = zip.get_channel(631272968093433856)
    await ctx.channel.set_permissions(ctx.guild.default_role, send_messages=False)
    suggestions = zip.get_channel(631881727064801280)
    await ctx.channel.set_permissions(ctx.guild.default_role, send_messages=False)
    general = zip.get_channel(630907637919121420)
    await ctx.channel.set_permissions(ctx.guild.default_role, send_messages=False)
    memes = zip.get_channel(631273005489586176)
    await ctx.channel.set_permissions(ctx.guild.default_role, send_messages=False)
    wholesome_me = zip.get_channel(631273030265602090)
    await ctx.channel.set_permissions(ctx.guild.default_role, send_messages=False)
    music_d = zip.get_channel(631273090260926475)
    await ctx.channel.set_permissions(ctx.guild.default_role, send_messages=False)
    no_mic = zip.get_channel(631273262047035413)
    await ctx.channel.set_permissions(ctx.guild.default_role, send_messages=False)
    bot_com = zip.get_channel(631273294170947605)
    await ctx.channel.set_permissions(ctx.guild.default_role, send_messages=False)
    await ctx.send("**SERVER HAS BEEN LOCKED DOWN**")

此模块声明“是否”正确？

@NgModule({
  exports: [SvgViewer],
  declarations: [SvgViewer],
})

因为它使用imports: [HttpClientModule]？通用模块中的IIUC应该声明其依赖性。

Answer 1

不。因为它已导入到已经导入HttpClientModule的模块中，所以依赖项注入程序已经知道HttpClientModule。参见（https://github.com/angular/material.angular.io/blob/051363fff1f993dd77f70ea9ebf917fbc3f99426/src/app/app-module.ts）

使用HttpClient的模块是否应该在导入中声明HttpClientModule？
