java - 添加 "Content-Encoding" header 到请求后出现 400 错误

Question

我正在尝试通过向请求添加“Content-Encoding” header 来执行 POST 调用。这是我的代码

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);

<小时/>

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 header

响应称“Content-Encoding” header 丢失。谁能在这里帮助我，并指出我正确的做法？

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();
