java如何将头信息作为键值对传递给使用jersey的rest服务

Question

我得到了一个web服务的url，它以json格式返回值，但它需要get请求中的头信息作为键值对，例如，我需要将Emp_代码作为键传递，“xyz”作为值来获取postman中所有员工的详细信息。下面是我试过的代码

private static void getEmployees()
  {
     final Client client = new Client();
        final WebResource webResource = client.resource("http://abc/springrestexample/employees");
        final ClientResponse response = webResource.accept("application/json").get(ClientResponse.class);
        if (response.getStatus() != 200)
        {
            throw new RuntimeException("Failed Http Error code " + response.getStatus());
        }
        final String output = response.getEntity(String.class);

        System.out.println("Output from Server .... \n");
        System.out.println(output);
}

在上面的代码中，我应该如何传递标题信息（键值）以获得所需的结果

Answer 1

你可以加上。接受后的标题（“键”、“值”）。请在下面查看

final Client client = new Client();
        final WebResource webResource = client.resource("http://abc/springrestexample/employees");
        final ClientResponse response = webResource.accept("application/json").header("KEY", "Value" ).get(ClientResponse.class);
        if (response.getStatus() != 200)
        {
            throw new RuntimeException("Failed Http Error code " + response.getStatus());
        }
        final String output = response.getEntity(String.class);

        System.out.println("Output from Server .... \n");
        System.out.println(output);
