为什么在使用Jersey客户端的POST呼叫中出现400错误代码

Question

I am calling a post request using Jersey rest client which contains no request body but contains authorization header. I am always getting 400 error. I tried from postman i got 200 response. Here is my code

ClientResponse response = null;
Client cliente=Client.create();
cliente.addFilter(new LoggingFilter(System.out));
WebResource webResource=cliente.resource("https://URL/token");
Builder builder = webResource.accept("application/json");
builder.type(MediaType.APPLICATION_JSON);
builder.header("Authorization", "Basic YbjjkwliOTQtNjRiYy00NWE5LWFhMzQtMTFhNDkyZZjNTVlOjZjYjk2OTMwNGE5YTQ3OTlhODVjZTM5MDFiMDEyMTI2";
builder.post(ClientResponse.class,Entity.json(""));

Don't use the way you are trying right now. Use HttpAuthenticationFeature from Jersey like this

HttpAuthenticationFeature feature = HttpAuthenticationFeature.basic("username", "password");

 

final Client client = ClientBuilder.newClient();

client.register(feature);

If you are getting 200 success respone in postman and failure response in your application then you need to check your api with another api tester online tool. I had the same issue i put / at the last of end point.
