java - 使用 POST 使用 Content-Type:application/x-www-form-urlencoded （Content-Type:application/json 工作正常）的“路由中出现意外异常”

Question

我正在使用“vert.x”创建一个除了“Content-Type:application/x-www-form-urlencoded”之外的发布请求。并得到“路由 java.lang.NullPointerException 中的意外异常”，但是当我删除内容类型时，相同的请求工作正常。

我正在使用 vert.x 3.3.3 并尝试使用垂直创建路线。

Router router = Router.router(vertx);

```
//--- 
router.post("/sample-api").handler(new myHandler());

   // This allows post with content-type "application/json" and "Unexpected 
   // exception in route java.lang.NullPointerException" error with 
   // "application/x-www-form-urlencoded"


//---
router.route(HttpMethod.POST, "/sample-api").consumes("application/x-www-form-urlencoded").handler(new myHandler());

   // This gives 404 on the post with content-type "application/json" and 
   // "Unexpected exception in route java.lang.NullPointerException" error 
   // with "application/x-www-form-urlencoded"

Error msg with content-type : application/x-www-form-urlencoded
