如何使用Jersey Client API在RESTful呼叫上添加标题 [英] How to add Headers on RESTful call using Jersey Client API

问题描述

 头文件：
 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}} 
  
 
 
以下是我的代码： 
 
 
  try 
 {
客户端客户端= Client.create（）; 
 WebResource webResource = 
 client.resource（https://api.example.com/1/realTime?json= 
 {selection：{includeAlerts：true， selectionType： 注册， selectionMatch： ， isTheEvent： 真， includeRuntime： 真}}）; 
 $ b $ //添加头文件：Content-Type：application / json; charset = UTF-8 
 webResource.setProperty（Content-Type，application / json; charset = UTF-8 ）; 
 
 //添加标题：授权承载Rc7JE8P7XUgSCPogsdfdLMfITqQQrjg 
 value =承载+值; 
 webResource.setProperty（Authorization，value）; 
 
多值图< String，String> queryParams = new MultivaluedMapImpl（）; 
 queryParams.add（json，js）; 
 
 //从RESTful Server获取响应
 jsonStr = webResource.get（String.class）; 
 System.out.println（Testing：）; 
 System.out.println（jsonStr）; 
 
 $ b 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？通过com.sun.jersey.api.client.WebResource.handle（WebResource.java:607）返回响应状态500 
 com.sun.jersey.api.client.WebResource.get（$） WebResource.java:187）
 at net.yorkland.restful.GetThermostatlist.GetThermostats（GetThermostatlist.java:60）
  
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请求添加标题。
 
 
 
谢谢 
 
解决方案
我认为你正在寻找标题（名称，值）方法。请参阅  WebResource.header（String，Object）  
 
 
注意它会返回一个Builder，所以你需要将输出保存在你的webResource变量中。
 
Here is the Format for RESTful call:
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"}}
Here is my codes:
                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);
                }
But it returns error
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)
    at com.sun.jersey.api.client.WebResource.get(WebResource.java:187)
    at net.yorkland.restful.GetThermostatlist.GetThermostats(GetThermostatlist.java:60)
I think I didn't add headers correctly. 

Can someone help me to fix it? Please give me advice how to add headers on request.

Thank you
解决方案
I think you're looking for header(name,value) method. See WebResource.header(String, Object)

Note it returns a Builder though, so you need to save the output in your webResource var.
