我正忙着使用IBM worklight,我正在尝试创建一个适配器来从Google Places API提供一些数据.
我想打电话给这个网址:
https://maps.googleapis.com/maps/api/place/search/json?key=AIzaSyCTlPms1pvhzeoRrBao5qW-DJMI_CWcbAM&location=52.0700,1.1400&radius=10000&sensor=false&name=coffee

执行此URL在浏览器中工作正常,并显示我试图通过Worklight获取的一些不错的JSON.
Worklight适配器是用Javascript创建的,这是我到目前为止所拥有的:
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;
}
}

当我测试上面的内容时,这是我进入控制台的结果:

我认为,这可能是因为适配器请求为HTTP,而应该使用HTTPS.
如果我在浏览器中更改了使用HTTP的请求,则会显示类似的结果.
问题:我可以通过更改上面的Javascript来发出HTTPS请求,还是我误解了worklight适配器?

如果您未在请求中指定主机标头,则看起来像googleapis将无效.添加后,一切正常:
这是适配器的XML部分
<connectivity>
<connectionPolicy xsi:type="http:HTTPConnectionPolicyType">
<protocol>https</protocol>
<domain>maps.googleapis.com</domain>
<port>443</port>
</connectionPolicy>
<loadConstraints maxConcurrentConnectionsPerNode="2" />
</connectivity>

这是适配器的JS:
function doGet() {
var input = {
method : 'get',
returnedContentType : 'json',
path : 'maps/api/place/search/json',
headers: {
Host: 'maps.googleapis.com'
},
parameters : {

}
};
var response = WL.Server.invokeHttp(input);
return response;
