这是我的代码。如您所见，我有一个主链和一个Observables.map运算符的子串。
时刻一切正常 return this.billingRest.getCurrentPlan(teamId);
}).map((response: any) => {
const currentPlan = response.plan;
它不会触发，下一个映射运算符不会等待响应，它会抛出错误'无法读取未定义的属性'。它的行为就像它没有订阅，但实际上它有。当我使用toPromise（）转换获取CurrentPlan时，下一个映射不会等待结果，但函数起火了。我不知道怎么做，我不明白那个功能的行为。
getCurrentPlan (teamId) {
console.log('GET CURRENTPLAN PRZED RESTEM')
return this.http.get(this.restUrl + this.plansPrefix + '/' + teamId + '/getCurrentPlan', {observe: 'response'})
.map( (response) => {
console.log(" FULFILLED LOG ");
return response.body;
})
.catch((response) => {
console.log('GETCURRENTPLANNIEDZIALA');
return Observable.throw(response);
});
};

在这个块中
return this.billingRest.getCurrentPlan(teamId);
}).map((response: any) => {
const currentPlan = response.plan;
我没有看到 teamId 来自哪里。也许你的意思是this.teamId？
所以也许，'无法读取未定义的属性'可能来自response.plan，因为响应未定义？
作为奖励，我想这个
const screenPlans = [];
for (let i = 0; i < plans.length; i++) {
const plan = plans[i];
const screenPlan = this.transformPlanToView(plan);
screenPlans.push(screenPlan);
};
可以写成这个
const screenPlans = plans.map(plan => this.transformPlanToView(plan))

这是一个完整的函数，teamId由sessionService.getCurrentTeam（）。uuid编写。切换地图和合并地图不起作用。我不知道出了什么问题。
