角度8中的此处API的无效凭证

Question

我一直在尝试从邮政编码获取位置，但是在控制台中出现此错误

Uncaught SyntaxError: Unexpected token '<'
geocode.component.ts:33 Error: [timeout] https://geocoder.api.here.com/6.2/geocode.json?xnlp=CL_JSMv3.0.17.0&app_id=null&app_code=null&searchText=boston request failed

单击此按钮时，显示的凭据无效。应该怎么办？

您需要包括您的API密钥。

https://geocoder.ls.hereapi.com/6.2/geocode.json?apiKey={YOUR_API_KEY}&searchtext=425+W+Randolph+Chicago

有关为here api创建API密钥的更多信息，请查看docs。
