Google maps api 3 如何从GoogleMapsAPI处理json

Google maps api 3 如何从GoogleMapsAPI处理json,google-maps-api-3,coldfusion,Google Maps Api 3,Coldfusion,从 如果我进入: http://maps.googleapis.com/maps/api/distancematrix/json?origins=Hickory+NC&destinations=Niagra+Falls+NY&sensor=false&units=imperial 然后我得到: { "destination_addresses" : [ "Niagara Falls, NY, USA" ], "origin_addresses" : [ "H

如果我进入:

http://maps.googleapis.com/maps/api/distancematrix/json?origins=Hickory+NC&destinations=Niagra+Falls+NY&sensor=false&units=imperial
然后我得到:

{
   "destination_addresses" : [ "Niagara Falls, NY, USA" ],
   "origin_addresses" : [ "Hickory, NC, USA" ],
   "rows" : [
      {
         "elements" : [
            {
               "distance" : {
                  "text" : "667 mi",
                  "value" : 1072719
               },
               "duration" : {
                  "text" : "11 hours 21 mins",
                  "value" : 40835
               },
               "status" : "OK"
            }
         ]
      }
   ],
   "status" : "OK"
}
但如果我发出这个命令:

<cfhttp method="get" result="myContent" url="http://maps.googleapis.com/maps/api/distancematrix/json">
    <cfhttpparam type="url" name="origins" value="Hickory+NC">
    <cfhttpparam type="url" name="destinations" value="Niagra+Falls+NY">
    <cfhttpparam type="url" name="sensor" value="false">
    <cfhttpparam type="url" name="units" value="imperial">
</cfhttp>
<cfdump var="#myContent#">

然后我得到一个StatusCode=200OK,但Text=NO的结构。

getAsBinary=“never”
添加到cfhttp中

<cfhttp method="get" result="myContent" url="http://maps.googleapis.com/maps/api/distancematrix/json" getAsBinary="never">
    <cfhttpparam type="url" name="origins" value="Hickory+NC">
    <cfhttpparam type="url" name="destinations" value="Niagra+Falls+NY">
    <cfhttpparam type="url" name="sensor" value="false">
    <cfhttpparam type="url" name="units" value="imperial">
</cfhttp>
<cfdump var="#myContent#">

我想自己试试,但我在打电话。尽量不要在param标记中对您的值进行URL编码。只需使用空格,而不是+,然后查看是否得到不同的结果。确保您正在查看myContent.Filecontent。我运行了你的代码,得到了一个有效的结果。没有修改。
