我想创建一个执行GET和POST的服务,并在组件上使用它。最好的方法是什么?
auth.service.ts
getToken() {
return this.http.get(this.getServerUrl() + '/token');
}
login(username: string, password: string) {
return this.getToken()
.subscrive((response: Response) => {
return this.http.post(this.getServerUrl() + '/login'
, JSON.stringify({username: username, password: passowrd}))
});
}
login.component.ts
login(username, password) {
event.preventDefault();
this.authService.login(username, password)
.subscribe(
response => {
console.log("success");
},
error => {
console.log(error.text());
}
);
}

假设您需要此令牌一次,则承诺将返回一次,然后执行http post
this.getToken()
.then(response=>{
if(response){
this.http.post ....
}
});
