使用REST API下载XML文件

Question

I need to write a REST api which would send an XML file as response. I am confused with what MediaType should be defined as the response.

 @Produces(MediaType.APPLICATION_OCTET_STREAM)

or

 @Produces(MediaType.APPLICATION_XML)

The API will be served from a GET request and I want the file to be downloaded in the client side.

Answer 1

我将使用@Produces(MediaType.APPLICATION_XML) ，因为@Produces(MediaType.APPLICATION_OCTET_STREAM)是application/octet-stream的常量，通常用于二进制类型（例如视频，音乐和东西）

Answer 2

I suggest dont send file directly. read file at server end and send the file content as a response.

so it will look like

@GET
@Produce("application/xml")
    public Response sendData(){
      //code to read file and store in a string object

     return Response.built.ok(string object);
    }
