Question

我是网络服务的新手。我试图从一个Android应用程序发送一个InputStream到一个像Rest框架一样使用Jersey 2.22的服务器，但我得到415不支持的媒体类型错误。这是我的客户端代码（我使用Loopj的AsyncHttpClient）：

   client.addHeader("Content-Type", "application/octet-stream");
   final RequestParams requestParams = new RequestParams();
   requestParams.put("file", myInputStream);

   client.post("MyUrl", requestParams, new AsyncHttpResponseHandler() {
                    @Override
                    public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
                        System.out.println("Success");
                    }

                    @Override
                    public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
                        if(responseBody != null)
                            System.out.println(new String(responseBody, StandardCharsets.UTF_8));
                        System.out.println(error.getMessage());
                        System.out.println("Failure");
                    }
                });

服务器端代码是：

@Path("/schedule")
public class schedule {

@POST
@Secured
@Consumes(MediaType.APPLICATION_OCTET_STREAM)
public Response getScenario(@FormDataParam("file")InputStream payload){

    System.out.println("I'm in");
    //Do stuff with payload
 return Response.ok().build();
}

但如果不是@FormDataParam，我只会把

public Response getScenario(InputStream payload)

我收到的inputStream没有任何415错误（当然在这种情况下inputStream也包含httpBody）。

在网上搜索我已阅读有关依赖性问题，但一切似乎都没问题。这是我的pom.xml和资源配置：

final ResourceConfig rc = new ResourceConfig().packages("MyPackages", "org.glassfish.jersey.examples.multipart");
rc.register(MultiPartFeature.class);

Answer 1

我解决了只是从@Consumes（MediaType.APPLICATION_OCTET_STREAM）更改@Consumes注释的问题至 @Consumes（MediaType.MULTIPART_FORM_DATA）

并从客户端http请求中删除标头

使用@FormDataParam的泽西不支持的mediatype
