任何人都可以参考或向我展示如何使用 Terraform 创建 AWS Lambda 触发器的示例吗？

在AWS控制台中，单击函数名称并选择配置选项卡后，您可以创建触发器，例如SNS触发器

我有以下布局

<!-- Page Content -->
<ion-content class="app-page card-list">
  <!--
  -->
  <ion-searchbar 
    [(ngModel)]="searchinput"
    (ionInput)="onInput(search)"
    placeholder="Search Contacts" light #search>
  </ion-searchbar>

  <!-- Refresher -->
  <ion-refresher (ionRefresh)="doRefresh($event)">
    <ion-refresher-content
      pullingIcon="arrow-dropdown"
      pullingText="Pull to refresh"
      refreshingSpinner="circles"
      refreshingText="Refreshing...">
    </ion-refresher-content>
  </ion-refresher>

  <!-- Contact List Start Here -->
  <ion-list>
    <!-- Foreach Contact in Contacts do -->
    <button ion-item  *ngFor="let contact of contacts" (click)="getContact(contact.id)" >
      <ion-avatar item-left>
         <img [src]="_DomSanitizationService.bypassSecurityTrustUrl('data:image/jpg;base64,' + contact.image_small)"    *ngIf="contact.image_small"/>
         <img src="img/nopic.png" text-center *ngIf="!contact.image_small"/>
      </ion-avatar>

      <h2>{{contact.name}}{{contact.parent_id? ", " + contact.parent_id[1] : ""}}</h2>
      <p><b>Mobile: </b>{{contact.mobile || "" }}&nbsp;<b>Phone: </b>{{contact.phone || …

无法使用jruby启动rails5,收到以下错误.

我是否知道测试Object的正式方法(来自服务器的响应),如果它是一个空对象？

目前,我的做法是利用jQuery.

  this.http.post(url, data, {headers: headers}).then(
    result =>
     {
       if (!$.isEmptyObject(result)) {
        -- run code here --
       }else{
        -- log warning --
       }
     }

我认为这是正统的,并希望找到一种仅使用打字稿的方法.

谢谢.

我在 Go 中有一个函数：

func login(user *C.char) *C.char {
    cstr := C.CString("Hello World")
    defer C.free(unsafe.Pointer(cstr))
    return cstr 
}

我的红宝石代码如下

module GoLib
  extend FFI::Library
  ffi_lib './golib.so'

  attach_function :login, [:string], :string
end

GoLib.login("User1") #=> "p\x9A\xA0\xDB\x16V"

它不会作为 ruby​​ 字符串返回。我该如何解决这个问题？
