【问题描述】:
这是我的代码大纲(省略了一些细节)。基本上我只想在单击一个按钮时发出两个类似的 API 请求,然后有一个函数可以处理两个请求的结果,但我无法弄清楚。
class myClass extends Component {
constructor(props) {
super(props);
this.API_KEY_ONE = ‘firstapikey’
this.API_KEY_TWO = ‘secondapikey’
this.state = {
city: 'undefined',
state: 'undefined'
}
}
callOne() {
this.REQUEST_URL = 'https://api.wunderground.com/api/' + this.API_KEY_ONE + '/geolookup/conditions/astronomy/forecast/q/.json';
fetch(this.REQUEST_URL).then((response) => response.json()).then((responseData) => {
this.setState({
city: responseData.location.city
});
}).done();
}
callTwo() {
this.REQUEST_URL = 'https://api.DifferentSite.com/api/' + this.API_KEY_TWO + '/geolookup/conditions/astronomy/forecast/q/.json';
fetch(this.REQUEST_URL).then((response) => response.json()).then((responseData) => {
this.setState({
state: responseData.location.state
});
}).done();
}
// where to put this? when both requests finish, pass both to new component
this.props.navigator.push({
title: 'Forecast',
component: Forecast,
passProps: {city: this.state.city, state: this.state.state}
});
getForecast() {
this.callOne();
this.callTwo();
}
<TouchableHighlight onPress={() => this.getForecast()} />
