这是RESTful调用的格式:
HEADERS:
Content-Type: application/json;charset=UTF-8
Authorization: Bearer Rc7JE8P7XUgSCPogjhdsVLMfITqQQrjg
REQUEST:
GET https://api.example.com/1/realTime?json={"selection":{"includeAlerts":"true","selectionType":"registered","selectionMatch":"","isTheEvent":"true","includeRuntime":"true"}}
这是我的代码:
try
{
Client client = Client.create();
WebResource webResource =
client.resource("https://api.example.com/1/realTime?json=
{"selection":{"includeAlerts":"true","selectionType":"registered","selectionMatch":"","isTheEvent":"true","includeRuntime":"true"}}");
//add header:Content-Type: application/json;charset=UTF-8
webResource.setProperty("Content-Type", "application/json;charset=UTF-8");
//add header: Authorization Bearer Rc7JE8P7XUgSCPogsdfdLMfITqQQrjg
value = "Bearer " + value;
webResource.setProperty("Authorization", value);
MultivaluedMap<String, String> queryParams = new MultivaluedMapImpl();
queryParams.add("json", js);
//Get response from RESTful Server
jsonStr = webResource.get(String.class);
System.out.println("Testing:");
System.out.println(jsonStr);
}
catch (Exception e)
{
System.out.println (e.getMessage());
e.printStackTrace();
System.exit(0);
}
但它返回错误
com.sun.jersey.api.client.UniformInterfaceException: GET https://api.example.com/1/realTime? returned a response status of 500
at com.sun.jersey.api.client.WebResource.handle(WebResource.java:607)

我想我没有正确添加标题。
有人可以帮我解决吗?请给我建议如何根据要求添加标题。
谢谢
我认为你正在寻找标题(名称,值)方法。见WebResource.header(String, Object)
请注意,它会返回一个Builder,因此您需要将输出保存在webResource var中。
我使用header(name,value)方法并返回webResource var:
Client client = Client.create();
WebResource webResource =client.resource("uri");
MultivaluedMap<String, String> queryParams = new MultivaluedMapImpl();
queryParams.add("json", js); //set parametes for request
appKey = "Bearer " + appKey; // appKey is unique number
//Get response from RESTful Server get(ClientResponse.class);
ClientResponse response = null;
response = webResource.queryParams(queryParams)
.header("Content-Type", "application/json;charset=UTF-8")
.header("Authorization", appKey)
.get(ClientResponse.class);
String jsonStr = response.getEntity(String.class);
试试这个!
Client client = ClientBuilder.newClient();
String jsonStr = client
.target("http:....")
.request(MediaType.APPLICATION_JSON)
.header("WM_SVC.NAME", "RegistryService")
.header("WM_QOS.CORRELATION_ID", "d1f0c0d2-2cf4-497b-b630-06d609d987b0")
.get(String.class);
P.S你可以添加任意数量的标题!
如果你想为所有Jersey响应添加标题,你也可以使用来自ContainerResponseFilter
的Jersey's filter documentation:
import java.io.IOException;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerResponseContext;
import javax.ws.rs.container.ContainerResponseFilter;
import javax.ws.rs.core.Response;
@Provider
public class PoweredByResponseFilter implements ContainerResponseFilter {
@Override
public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext)
throws IOException {
responseContext.getHeaders().add("X-Powered-By", "Jersey :-)");
}
}
确保使用@Provider
注释或通过web.xml
的传统方法在项目中正确初始化它。
String sBodys="Body";
HashMap<String,String> headers= new HashMap<>();
Client c = Client.create();
WebResource resource = c.resource("http://consulta/rs");
WebResource.Builder builder = resource.accept(MediaType.APPLICATION_JSON);
builder.type(MediaType.APPLICATION_JSON);
if(headers!=null){
LOGGER.debug("se setean los headers");
for (Map.Entry<String, String> entry : headers.entrySet()) {
String key = entry.getKey();
String value = entry.getValue();
LOGGER.debug("key: "+entry.getKey());
LOGGER.debug("value: "+entry.getValue());
builder.header(key, value);
}
}
ClientResponse response = builder.post(ClientResponse.class,sBodys);
此代码段工作正常,用于使用Jersey客户端发送承载令牌。
WebTarget webTarget = client.target("endpoint");
Invocation.Builder invocationBuilder = webTarget.request(MediaType.APPLICATION_JSON);
invocationBuilder.header("Authorization", "Bearer "+"Api Key");
Response response = invocationBuilder.get();
String responseData = response.readEntity(String.class);
System.out.println(response.getStatus());
System.out.println("responseData "+responseData);
