得到这个错误。

ShareButtonComponent.html:2 ERROR Error: No provider for Http!

    at noProviderError (core.es5.js:1207)

Answer 1

您缺少http导入

import { HttpModule } from '@angular/http';

@NgModule({
    imports: [ BrowserModule, HttpModule,ShareButtonsModule.forRoot()],// missing http import module
    providers: [],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})
....

演示分享按钮link点击联系人卡片

在分享按钮的官方Wiki链接中需要HttpModule请查看link

ngx-sharebuttons获取Http的无提供程序
