我想进行升级以使用 HttpClient

推荐答案

我认为您应该没问题.引用新软件包后，只需确保您的ng build --prod没有损坏.

I think you should be fine. Once you reference the new packages just make sure that your ng build --prod is not breaking.

如果要使用新的HttpClient，则已更改引用@angular/http中Http的代码的所有部分，并根据样式指南将其替换为@angular/common/http中的HttpClient.

If you want to use the new HttpClient you have change all parts of your code that referencing Http from @angular/http and replace that with HttpClient from @angular/common/http according with styleguide.

此外，除非您不关心测试，否则还必须更改所有引用旧的Http的相关.spec文件，然后使用ng t进行测试.

Also you have to change to all related .spec files that referencing old Http as well, then test with ng t, unless you does not care about tests.
