将“Content-Encoding”头添加到请求后出现400错误

Question

我试图通过向请求添加“Content-Encoding”头来执行POST调用。这里是我的代码

Invocation.Builder builder = 
webTarget.request(MediaType.APPLICATION_XML).header("Content-Encoding", 
"xml").accept(MediaType.TEXT_PLAIN); 
String xmlRequest= 
buildMerchantPreferencesRequest(accountNumber,emailID,thresholdValue); 
response = header.post(Entity.xml(xmlRequest.toString())); 

String value = response.readEntity(String.class); 
Thread.sleep(5000); 
System.out.println("Service STATUS : "+response.getStatus()); 
System.out.println("Response message : "+value); 

---

返回响应如下： 状态：400 响应消息：请求服务PreferencesLifecycle版本1.0- 211.0-35789706缺少Content-Encoding头

回应说： “内容编码”标题丢失。 任何人都可以在这里帮助我，并指出我正确的做法吗？

Response response; 
     String xmlRequest= buildMerchantNBPreferencesRequest(accountNumber,emailID,thresholdValue); 
     Variant variant = new Variant(MediaType.APPLICATION_XML_TYPE, null, null, "XML");   
     Invocation.Builder builder = merchantPreferencesClient.request().header("Content-Encoding", "XML").property("Content-Encoding", "XML"); 
     Invocation invocation = builder.header("Content-Encoding", "XML").buildPost(Entity.entity(xmlRequest, variant)); 
     response = invocation.invoke();
