我正在玩弄 IBM worklight,并试图创建一个适配器来从Google Places API提供一些数据。
我想调用这个 URL:
https://maps.googleapis.com/maps/api/place/search/json?key=AIzaSyCTlPms1pvhzeoRrBao5qW-DJMI_CWcbAM&location=52.0700,1.1400&radius=10000&sensor=false&name=coffee
在浏览器中执行此 URL 可以正常工作,并显示一些我试图通过 Worklight 获取的漂亮 JSON。
Worklight 适配器是用 Javascript 创建的,这是我目前所拥有的:
function getCoffeeHouses() {
var input = {
method : 'get',
returnedContentType : 'json',
path : 'maps/api/place/search/json',
parameters : {
'key' : 'AIzaSyCTlPms1pvhzeoRrBao5qW-DJMI_CWcbAM',
'location' : '52.0700,1.1400',
'radius' : '10000',
'sensor' : 'false',
'name' : 'coffee'
}
};
var response = WL.Server.invokeHttp(input);
// Extract latitude and longitude from the response.
var type = typeof response;
if ("object" == type) {
if (true == response["isSuccessful"]) {
// Return JSON object with lat and lng.
return response["results"];
}
else {
// Returning null. Web request was not successful.
return null;
}
}
else {
// Returning null. Response is not an object.
return null;
}
}
这是我在控制台中得到的结果,当我测试上述内容时:

我认为,这可能是因为适配器请求为 HTTP,而它应该使用 HTTPS。
如果我将请求更改为在浏览器中使用 HTTP,它会显示类似的结果。
问题:我可以通过更改上述 Javascript 来发出 HTTPS 请求,还是我误解了工作灯适配器?
