使用Oltu传递给OAuthTokenRequest时无法使用@ Context HttpServletRequest检索发布数据 [英] Unable to retrieve post data using ,@Context HttpServletRequest when passed to OAuthTokenRequest using Oltu

问题描述

我正在使用Oltu作为Oauth2。

I'm using Oltu for Oauth2.

当使用@Context HttpServletRequest请求时，我无法检索发布数据

When using @Context HttpServletRequest request I am unable to retrieve post data

当我使用@FormParam时，我能够检索帖子数据。

When I am using @FormParam I am able to retrieve post data.

将请求传递给OAuthTokenRequest

On passing request to OAuthTokenRequest

OAuthTokenRequest oauthRequest = new OAuthTokenRequest(request);

我收到以下错误

{error：invalid_request，error_description：缺少grant_type参数值}

{"error":"invalid_request","error_description":"Missing grant_type parameter value"}

调试oltu OAuthTokenRequest类以下代码用于检索参数值

When debugging on the oltu OAuthTokenRequest class following code is used to retrive param value

public String getParam(String name) {
        return this.request.getParameter(name); // from request it is unable to get post data.As i am getting request object using  @Context HttpServletRequest request .
    }

据说使用@Context HttpServletRequest请求无法获得帖子使用@Context的数据HttpServletRequest请求
所以，我的问题是

It is said that using @Context HttpServletRequest request it is not possible to get post data for using @Context HttpServletRequest request So, my question is

如何在jax-ws
中获取包含帖子数据的HttpServletRequest请求这样我就可以将HttpServletRequest请求传递给OAuthTokenRequest
这是我的代码

How to get HttpServletRequest request with post data in jax-ws so that I can pass HttpServletRequest request to OAuthTokenRequest This is my code

@Path("/token")
public class TokenEndpoint {

 @POST
    @Consumes("application/x-www-form-urlencoded")
    @Produces("application/json")
    public Response authorize(@FormParam("state") String state,@Context HttpServletRequest request) throws OAuthSystemException {
        try {
        // here I am unable to get value of request.getParameter("state") 
       // but using (@FormParam("state") I am able to get value of post parameter state
            request.getParameter("state");
            // exception is thrown from following code 
            OAuthTokenRequest oauthRequest = new OAuthTokenRequest(request);

推荐答案

找到解决方法（阅读评论）。

Found a workaround (read the comments).

OLTU Issue＃26

Jersey正在消耗POST数据。

解决方案是包装HttpServletRequest并覆盖 getParameters（） 。

这是包装器：

Jersey is consuming the POST data.
The solution is to wrap the HttpServletRequest and override getParameters().
This is the wrapper:

public class OAuthRequestWrapper extends HttpServletRequestWrapper {

    private MultivaluedMap<String, String> form;

    public OAuthRequestWrapper(HttpServletRequest request, MultivaluedMap<String, String> form)
    { super(request); this.form = form; }

    @Override
    public String getParameter(String name) {
        String value = super.getParameter(name);
        if (value == null)
        { value = form.getFirst(name); }
        return value;
    }
}

这是实现令牌POST方法的方法：

And this is how to implement the token POST method:

@POST
@Path("/token")
@Consumes("application/x-www-form-urlencoded")
@Produces("application/json")
public Response token(@Context HttpServletRequest request, MultivaluedMap<String, String> form) {   

    [...]

    OAuthTokenRequest oauthRequest = new OAuthTokenRequest(new OAuthRequestWrapper(request, form));

    [...]

}
