java - 在 Jersey REST 服务中调用 Google Geocode API 导致内部 400 错误

Question

我在尝试在后端的 Jersey REST 服务调用中访问 Google 地理编码 API 时遇到问题。当我这样做时，会导致服务器上出现内部 HTTP 400 错误但是，直接通过浏览器或客户端调用来调用地理编码 API 是可行的此外，调用一个 Jersey REST 服务再调用另一个 Jersey REST 服务也是可行的直接调用任何东西都有效。将 Jersey 服务嵌套在另一个 Jersey 服务中是可行的。但在 Jersey 服务中嵌套 Google API 调用会失败。

调用位置服务(“A”)

JerseyClient client = JerseyClientBuilder.newClient();

JerseyWebTarget webTarget = client.target("http://localhost:8080/arenamaster-backend/api").path("tournaments").path("location");

JerseyInvocation.Builder invocationBuilder = webTarget.request(MediaType.APPLICATION_JSON);

String input = "10621 Braddock Road – Ste B, Fairfax, VA 22032";

Response response = invocationBuilder
                .post(Entity.entity(input, MediaType.TEXT_PLAIN));

定位服务:(“B”)

@POST
@Path("/location")
@Consumes(MediaType.TEXT_PLAIN)
@Produces(MediaType.APPLICATION_JSON)
@CrossOrigin
public Response getLatLngFromAddress(String address) {
    LatLng latlng = LocationUtility.geocode(address);

    return Response.status(200).entity(latlng).build();     
}

直接调用位置实用程序地理编码器(“C”)

String address = "10621 Braddock Road – Ste B, Fairfax, VA 22032";

LatLng latlng= LocationUtility.geocode(address); 

System.out.println(latlng);

调用 Google Geocode API(“D”)的地理编码函数

public static LatLng geocode(String address) {
    String address_key = address.replace(' ', '+');                 
    String API_key = "***hidden***";            

    String request = "https://maps.googleapis.com/maps/api/geocode/json?address=" + address_key + "&key=" + API_key;
    JerseyClient client = JerseyClientBuilder.newClient();

    JerseyWebTarget webTarget = client.target(request);

    JerseyInvocation.Builder invocationBuilder = webTarget.request(MediaType.APPLICATION_JSON);

    Response response = invocationBuilder
            .get(Response.class);

    if (response.getStatus()/100 != 2) {
        throw new RuntimeException("Failed : HTTP error code : "
                + response.getStatus());
    }

    String output = response.readEntity(String.class);

    LatLng latlng = null;

    try {
        JSONObject geocode = new JSONObject(output);
        JSONArray results = geocode.getJSONArray("results");
        JSONObject address_components = (JSONObject) results.get(0);
        JSONObject geometry = (JSONObject) address_components.get("geometry");
        JSONObject location = (JSONObject) geometry.get("location");
        latlng = new LatLng(location.getDouble("lat"), location.getDouble("lng"));
    }catch(Exception e) {
        e.printStackTrace();
    }

    return latlng;
}

调用示例测试中调用(“E”)

//call within a call sample test
JerseyClient client = JerseyClientBuilder.newClient();

JerseyWebTarget webTarget = client.target("http://localhost:8080/arenamaster-backend/api").path("test").path("func1");

JerseyInvocation.Builder invocationBuilder = webTarget.request(MediaType.TEXT_PLAIN);


Response response = invocationBuilder
    .get(Response.class);

if (response.getStatus()/100 != 2) {
    throw new RuntimeException("Failed : HTTP error code : "
        + response.getStatus());
}

System.out.println("Output from Server .... \n");
String output = response.readEntity(String.class);
System.out.println(output);

在一次调用中调用两个测试服务端点(“F”)

@GET
@Path("/func1")
@Produces(MediaType.TEXT_PLAIN)
@CrossOrigin
public Response testFunc1() {
    System.out.println("1st service invoked");
    String response = "";

    response = TestDAO.callSecondService();

    return Response.status(200).entity(response).build();
}

@GET
@Path("/func2")
@Produces(MediaType.TEXT_PLAIN)
@CrossOrigin
public Response testFunc2() {
    System.out.println("2nd service invoked");
    String response = "";

    response = TestDAO.getMessage();

    return Response.status(200).entity(response).build();
}

调用测试函数中调用:("G")

public static String callSecondService() {

    JerseyClient client = JerseyClientBuilder.newClient();

    JerseyWebTarget webTarget = client.target("http://localhost:8080/arenamaster-backend/api").path("test").path("func2");

    JerseyInvocation.Builder invocationBuilder = webTarget.request();


    Response response = invocationBuilder
            .get(Response.class);

    if (response.getStatus()/100 != 2) {
        throw new RuntimeException("Failed : HTTP error code : "
                + response.getStatus());
    }

    System.out.println("Output from Server .... \n");
    String output = response.readEntity(String.class);
    System.out.println(output);

    return output;
}

public static String getMessage() {
    return "Success!"; 
}

更新:

以下行中的调用测试 (E-F-G) 正常工作

WebTarget webTarget = client.target("http://localhost:8080/arenamaster-backend/api").path("test").path("func3");替换为:WebTarget webTarget = client.target("https://en.wikipedia.org/wiki/List_of_HTTP_status_codes");

Answer 1

阅读正文后发现 Google Geocode API 不接受非 UTF-8 字符编码。我必须更改这一行才能使其正常工作:

String request = "https://maps.googleapis.com/maps/api/geocode/json?address=" + new URLEncoder().encode(address_key, Charset.availableCharsets().get("UTF-8")) + "&key=" + API_key;
