使用React Native Google地图路线包自动启动导航 [英] Auto start navigation with React Native Google Maps Directions package

问题描述

我有一个要求，在加载谷歌地图应用程序时，必须自动启动导航。

当前场景 - 显示路线，但用户必须单击 start 开始导航
我找不到与之相关的任何标志？

发现这篇文章显示了google中使用的标志地图

谷歌地图官方文档显示使用它作为 dir_action = navigate 但我对如何将它翻译成 react-native-google -maps-directions package

任何想法我们如何解决这个问题？

解决方案

react-native-maps-directions 使用Directions API显示路线。请注意，Directions API不包含任何实时导航，仅用于显示路线。此外，Google Maps API还禁止实时导航。

查看Google Maps API服务条款第10.4（c，iii）段。它读取

没有导航。您不会将服务或内容用于或与（a）实时导航或路线指引;或者（b）自动或自动控制车辆。

来源： https://developers.google.com/maps/terms#10-license-restrictions

为了符合Google Maps API服务条款，您应该使用导航模式下的Google地图网址。

  var url =https://www.google.com/maps/dir/?api=1&travelmode=driving& ; dir_action =导航&安培;目的地=洛矶+; 
 Linking.canOpenURL（url）.then（supported => {
 if（！supported）{
 console.log（'不能处理url：'+ url）; 
} else {
 return Linking.openURL（url）; 
} 
}）。catch（err => console.error（'An error occurred'，err）） ; 
  

我希望这有助于您！

I have a requirement that on loading the google map application, have to automatically start the navigation.

Current scenario - It shows the route but user has to click on start to start navigation I couldn't find any flag associated for the same?

Found this article which shows the flags used in google maps

Official google maps docs shows to use it as dir_action=navigate but I am clueless on how to translate it into react-native-google-maps-directions package

Any idea how could we approach the problem?

解决方案

The react-native-maps-directions uses the Directions API to display routes. Please note that Directions API doesn't include any real-time navigation, it is meant only to show routes. The real-time navigation additionally is prohibited in the Google Maps APIs.

Have a look at the Google Maps API Terms of Service paragraph 10.4 (c, iii). It reads

No navigation. You will not use the Service or Content for or in connection with (a) real-time navigation or route guidance; or (b) automatic or autonomous vehicle control.

source: https://developers.google.com/maps/terms#10-license-restrictions

In order to be compliant with Google Maps API Terms of Service you should open the Google Maps app installed in your device using the Google Maps URLs in navigation mode.

var url = "https://www.google.com/maps/dir/?api=1&travelmode=driving&dir_action=navigate&destination=Los+Angeles";
Linking.canOpenURL(url).then(supported => {
    if (!supported) {
        console.log('Can\'t handle url: ' + url);
    } else {
        return Linking.openURL(url);
    }
}).catch(err => console.error('An error occurred', err)); 

I hope this helps!
