如何处理路由参数和 API 服务的这些嵌套订阅？
How to handle these nested subscription for route Param and API service?
this.route.params.subscribe(params => {
if (params.id) {
this.formService.getFormFieldValById(params.id).pipe(take(1)).subscribe(res => {
// bind response to form
});
}
});
this.route.queryParams.pipe(
switchMap(({id}) => {
return this.formService.getFormFieldValById(id);
})
).subscribe(res => {
// bind response to form
})
在这里您可以链接每个进程而不是嵌套订阅
