角度 6 中的嵌套 http 调用
我正在尝试在Angular 6中进行嵌套的HTTP呼叫工作。基本上，我试图通过一个循环迭代并进行两个服务器端呼叫，我想清除这两个响应中的数据。什么是最简单的方法？我下面的代码无法正常工作。
async search() {
const stockLists = ['GOOGL', 'FB', 'ABNB', 'LULU', 'CRM']
for await(const stock of stockLists) {
await this.apiservice.GetStockOverview(stock).subscribe(async data => {
await this.apiservice.GetCurrentStockData(stock).subscribe(currenStockdata => {
data.currentStockPrice = (currenStockdata['Global Quote']['05. price']);
this.stockDataOverview.push(data);
})
})
await this.sleep(12000);
}
}
注意 - 我在此处添加了计时器，因为我只能对此API拨打5个电话。
提前致谢
I am trying to make a nested Http call work in angular 6. Basically, i am trying to iterate through a for loop and make two server side calls, i want to purge the data from those two responses. Whats the easiest way to achieve this? My code below isn't working as expected.
async search() {
const stockLists = ['GOOGL', 'FB', 'ABNB', 'LULU', 'CRM']
for await(const stock of stockLists) {
await this.apiservice.GetStockOverview(stock).subscribe(async data => {
await this.apiservice.GetCurrentStockData(stock).subscribe(currenStockdata => {
data.currentStockPrice = (currenStockdata['Global Quote']['05. price']);
this.stockDataOverview.push(data);
})
})
await this.sleep(12000);
}
}
Note- i added the timer there because i can make only 5 calls per minute to this api.
thanks in advance

Have you tried to use forkJoin of RXJS
