Java Jersey 2用于StreamingOutput的客户端

我有一个

Jersey

服务，它将二进制数据输出为

StreamingOutput

，

MediaType.APPLICATION\u OCTET\u STREAM

---

如何使用Jersey2实现客户端，以处理来自此类服务的

响应

。

下面是实现Jersey 2客户端的一种方法，用于从REST服务下载文件，该服务使用

MediaType.APPLICATION_OCTET_STREAM

返回二进制数据作为

流输出-

    Client client = ClientBuilder.newClient();
    // change SERVER_URL, API_PATH and PATH as per REST API details
    WebTarget webTarget = client.target(SERVER_URL).path(API_PATH).path(PATH);

    Invocation.Builder invocationBuilder = webTarget.request();
    Response response = invocationBuilder.get();

    String contentDispositionHeader = response.getHeaderString("Content-Disposition");
    String fileName = contentDispositionHeader
            .substring(contentDispositionHeader.indexOf("filename=") + "filename=".length()).replace("\"", "");

    InputStream responseStream = response.readEntity(InputStream.class);

    // Set location here where you want to store downloaded file. 
    // It will replace the file if already exist in that location with same name.
    Files.copy(responseStream, Paths.get("H:/"+ fileName), StandardCopyOption.REPLACE_EXISTING);

    System.out.println("File is downloaded");

Jersey文档中有一个客户端API部分，请看以下示例：
