【中文标题】使用 ClientResponse Jersey 调用 Rest API【英文标题】：Issue calling Rest API using ClientResponse Jersey 【发布时间】：2016-02-06 05:45:53 【问题描述】：当我从“Advance Rest Client”chrome 扩展调用 rest 服务时遇到问题，我得到了正确的响应，但是当我使用“ClientResponse”Jersey 调用相同的 API 时，它给了我错误 500 internal server error..
这是我的 API 网址：http://www.saksfifthavenue.com/main/ProductDetail.jsp
请求数据：
"productCode":"0400087200629","sku_id":"1689949379651610","itemQuantity":"1","zipCode":"10010","radius":"10","bmForm":"get_stores_with_inventory "
public class JerseyClientPost
public static void main(String[] args)
try
Client client = Client.create();
WebResource webResource = client
.resource("http://www.saksfifthavenue.com/main/ProductDetail.jsp");
String input = "\"productCode\":\"0400087200629\",\"sku_id\":\"1689949379651610\",\"itemQuantity\":\"1\",\"zipCode\":\"10010\",\"radius\":\"10\",\"bmForm\":\"get_stores_with_inventory\"";
Product product = new Product();
product.setProductCode("0400087200629");
product.setItemQuantity("1");
product.setRadius("10");
product.setSku_id("1689949379651610");
product.setZipCode("10010");
product.setBmForm("get_stores_with_inventory");
ClientResponse response = webResource.post(ClientResponse.class, product);
System.out.println("Output from Server .... \n");
String output = response.getEntity(String.class);
System.out.println(output);
catch (Exception e)
e.printStackTrace();
来自服务器的输出 ....

【问题讨论】：
你有错误的堆栈跟踪吗？ 【参考方案1】：也许服务器不知道您正在发送 JSON。
你可以试试这样的：
ClientResponse response = webResource.accept("application/json")
.type("application/json").post(ClientResponse.class, product);
