Jersey客户端将内容类型标题设置为text / plain

Question

Using jersey client sending HTTP request. Content-Type header is automatically set as "application/json" (as a nature), but i want to changing "content-type" header with "text/plain" regardless of any specification, standards etc. Jersey version is 2.4.1.

Code

String target = "http://192.168.1.2:10000";
String path = "test3";

Client c = ClientBuilder.newClient ();
WebTarget target = c.target (target).path (path);

Entity<SubscriberBean> json = Entity.json (subscriber);
Builder request = target.request ();

String response = request.post(json, String.class);

Request

POST /test3 HTTP/1.1
Accept: text/html
Content-Type: application/json
User-Agent: Jersey/2.4.1 (HttpUrlConnection 1.6.0_17)
Host: 192.168.1.2:10000
Connection: keep-alive
Content-Length: 278

///**** Some json data ***///

Answer 1

instead of

request.post(json, String.class);

try to use

request.type(MediaType.TEXT_PLAIN).post(json, String.class);

Answer 2

在Entity.text(entityData)使用Entity.text(entityData)或Entity.entity(entityData, mediaType)方法代替Entity.json() 。
