Question

我在这里面临一个奇怪的问题

当我从web浏览器或java命令行在url下运行时

http://maps.googleapis.com/maps/api/distancematrix/json?origins=416%2063,Sweden&destinations=424%2069,Stor%C3%A5s%20Industrigatan%2020,Angered,G%C3%B6teborg&sensor=false

我得到以下结果

{
  "destination_addresses" : [ "Storås Industrigata 20, 424 69
Angered, Sweden" ],
  "origin_addresses" : [ "Gothenburg, Sweden" ],
  "rows" : [
     {
        "elements" : [
           {
              "distance" : {
                 "text" : "10.4 km",
                 "value" : 10388
              },
              "duration" : {
                 "text" : "15 mins",
                 "value" : 924
              },
              "status" : "OK"
           }
       ]
     }
  ],
  "status" : "OK"
}    

但当我从glassfish服务器运行相同的url时，我的意思是发送一个 来自的http请求 表格提交后我得到下面奇怪的回复

{ "destination_addresses" : [ "" ],
  "origin_addresses" : [ "Gothenburg, Sweden" ],
  "rows" : [
     {
        "elements" : [
           {
              "status" : "NOT_FOUND"
           }
        ]
     }
  ],
  "status" : "OK"
}

在这种情况下，请不要将目标地址为空，并且状态为 没有找到

我用来获取响应的Java代码是

private String getResponse(String URL) throws Exception {
        InputStream stream = new URL(URL).openStream();
        byte[] array = new byte[stream.available()];
        stream.read(array);
        return new String(array);
}

请引导我解决这个问题

谢谢

Answer 1

在Java中使用距离矩阵API时，我遇到了类似的问题。在我的请求中设置语言似乎可以让它工作：

    DistanceMatrixElement distanceMatrixElement;
    DistanceMatrix matrix;

    try
    {
        matrix = distanceMatrixApiRequest
                .origins(...)
                .destinations(...)
                .language("en")
                .await();
    }

使用https
除非谷歌不让你的软件连接

及 获取api密钥

请阅读以下内容： https://developers.google.com/maps/documentation/distance-matrix/start

https://maps.googleapis.com/maps/api/distancematrix/json?origins=416%2063,Sweden&destinations=424%2069,Stor%C3%A5s%20Industrigatan%2020,Angered,G%C3%B6teborg&sensor=false&key=YOUR_API_KEY

确保用实际的API密钥替换您的API密钥
