如何在main.ts中手动实例化Http服务 [英] How to instantiate Http service in main.ts manually

问题描述

我需要在main.ts中手动实例化Http.我使用如下所示的HTTP_PROVIDERS找到了一些答案，但看起来似乎已弃用HTTP_PROVIDERS.知道我该怎么做吗?

I need to instantiate Http in main.ts manually. I found some answer using HTTP_PROVIDERS like below, but looks like HTTP_PROVIDERS is deprecated. Any idea how can I do this?

const injector = ReflectiveInjector.resolveAndCreate([HTTP_PROVIDERS]);
const http = injector.get(Http);

然后我将使用此http对象来调用服务器，并在响应中引导appmodule.类似于以下代码:

I will then use this http object to call the server and bootstrap the appmodule in the response. Something like the code below:

http.get("app/config/config.json").map(res => res.json()).subscribe(resp=>{
      platformBrowserDynamic().bootstrapModule(AppModule);

})

推荐答案

您可以使用Fetch API:

What you can do is to use the Fetch API:

fetch('config.json').then(res => res.json()).then((resp) =>{
   platformBrowserDynamic().bootstrapModule(AppModule);
})
