Angular HttpClient:将HttpResponse转换为Response [英] Angular HttpClient: Convert HttpResponse to Response
问题描述
使用Http时，我们从@angular/http库获得响应类型为Response，类似地使用res.json()
While using Http we get response type as Response from @angular/http library, similarly converting to JSON using res.json()
但是通过使用@angular/common/http中的HttpClient，我们可以使用observe
But by using HttpClient from @angular/common/http we get direct JSON or HttpResponse by using observe
是否可以解决将类型从Response转换为HttpResponse的问题，或者是否可以通过其他任何方式从HtpClient获取响应，以便.json()起作用?
Is there any work around to convert type from Response to HttpResponse or any other way to get response from HtpClient so that .json() will work?
推荐答案
http客户端默认情况下会隐式调用res.json()，您无需自己手动进行设置，并将响应类型设置为responseType到
http client by default calls res.json() implicitly and you don't need to that manually yourself and set the respond type to responseType to json
JSON is an assumed default and no longer needs to be explicitly parsed
