如何在订阅中控制台记录结果？ [英] How do i console log the results inside the subscribe?

问题描述

在我的角度应用程序中，我正在调用服务并获取数据，一旦获取结果，我需要添加控制台日志。我在哪里可以添加控制台日志？

In my angular app i am calling a service and fetching the data, i need to add a console log once the results are fetched. where can i add console log?

 this.searchTerm.asObservable()
            .debounceTime(300)      
            .distinctUntilChanged() 
            .switchMap(term => this.doFind(term))
            .subscribe(data => this.results = data
            , error => {
                this.errorMessage = error;
            });

推荐答案

使用代码块

this.searchTerm.asObservable()
        .debounceTime(300)      
        .distinctUntilChanged() 
        .switchMap(term => this.doFind(term))
        .subscribe(data => {
           this.results = data;
           console.log('data', data);
        })
        , error => {
            this.errorMessage = error;
        });

或 do 运算符

 this.searchTerm.asObservable()
        .debounceTime(300)      
        .distinctUntilChanged() 
        .switchMap(term => this.doFind(term))
        .do(val => condole.log(val))
        .subscribe(data => this.results = data
        , error => {
            this.errorMessage = error;
        });
