Google app engine 试图在GAE中使用google api客户端访问google places

我正在尝试使用如下代码从appengine访问google places api：

字符串PLACES\u DETAILS\u URL=”https://maps.googleapis.com/maps/api/place/details/json";

我不知道这是否是推荐的方式。如果是这样，为什么不起作用？如果我直接在浏览器中输入请求，它会起作用，但使用此代码，它总是返回我“请求被拒绝”

提前感谢。

最后很简单，我混合了get和post动词：

HttpTransport transport = new UrlFetchTransport();
        // add default headers
        GoogleHeaders defaultHeaders = new GoogleHeaders();
        transport.defaultHeaders = defaultHeaders;
       transport.defaultHeaders.put("Content-Type", "application/json");
       JsonCParser parser = new JsonCParser();
        parser.jsonFactory = new JacksonFactory();
        transport.addParser(parser);

        // build the HTTP GET request and URL
        HttpRequest request = transport.buildGetRequest();
        request.setUrl("https://maps.googleapis.com/maps/api/place/details/json?reference=CmRYAAAAciqGsTRX1mXRvuXSH2ErwW-jCINE1aLiwP64MCWDN5vkXvXoQGPKldMfmdGyqWSpm7BEYCgDm-iv7Kc2PF7QA7brMAwBbAcqMr5i1f4PwTpaovIZjysCEZTry8Ez30wpEhCNCXpynextCld2EBsDkRKsGhSLayuRyFsex6JA6NPh9dyupoTH3g&sensor=true&key=<APIKEY>");


        try {
            HttpResponse response =  request.execute();
            String r = response.parseAsString();

HttpTransport-transport=new-urlfetchttransport（）；
//添加默认标题
GoogleHeaders defaultHeaders=新的GoogleHeaders（）；
transport.defaultHeaders=defaultHeaders；
transport.defaultHeaders.put（“内容类型”、“应用程序/json”）；
JsonCParser parser=新的JsonCParser（）；
parser.jsonFactory=new JacksonFactory（）；
addParser（解析器）；
//构建HTTP GET请求和URL
HttpRequest请求=transport.buildGetRequest（）；
request.setUrl（“https://maps.googleapis.com/maps/api/place/details/json?reference=CmRYAAAAciqGsTRX1mXRvuXSH2ErwW-jCINE1aLiwP64MCWDN5vkXvXoQGPKldMfmdGyqWSpm7BEYCgDm-IV7KC2PF7QA7RMAWBBACQMR5I1F4PWTPAOVIZJJYSCEZTRY8EZ30WPEHCNCxPYNEXTCLD2EBSDKRKSGHSLAYURYFSEX6JA6NPH9DYUPOTH3G&sensor=true&key=“）；
试一试{
HttpResponse response=request.execute（）；
字符串r=response.parseAsString（）；

HttpTransport transport = new UrlFetchTransport();
        // add default headers
        GoogleHeaders defaultHeaders = new GoogleHeaders();
        transport.defaultHeaders = defaultHeaders;
       transport.defaultHeaders.put("Content-Type", "application/json");
       JsonCParser parser = new JsonCParser();
        parser.jsonFactory = new JacksonFactory();
        transport.addParser(parser);

        // build the HTTP GET request and URL
        HttpRequest request = transport.buildGetRequest();
        request.setUrl("https://maps.googleapis.com/maps/api/place/details/json?reference=CmRYAAAAciqGsTRX1mXRvuXSH2ErwW-jCINE1aLiwP64MCWDN5vkXvXoQGPKldMfmdGyqWSpm7BEYCgDm-iv7Kc2PF7QA7brMAwBbAcqMr5i1f4PwTpaovIZjysCEZTry8Ez30wpEhCNCXpynextCld2EBsDkRKsGhSLayuRyFsex6JA6NPh9dyupoTH3g&sensor=true&key=<APIKEY>");


        try {
            HttpResponse response =  request.execute();
            String r = response.parseAsString();
