发布期间指定内容类型时，Grails无法解析请求 [英] Grails fails to parse request when content type is specified during post

问题描述

使用wget我在正文中使用xml将两个帖子发布到相同的url.第一部作品.第二个具有指定的内容类型，它不起作用.为什么会这样?即使指定了内容类型，我怎么也无法解析请求?

Using wget I make two posts to the same url with xml in the body. The first works. The second has the content type specified and it does not work. Why is this and how do I get grails to parse the request even when the content type is specified?

第一个wget:

wget http://localhost:8080/myApp/myMoeView/save --post-file=xmltest.xml

Grails日志(请注意解析的参数"):

第二个wget:

wget http://localhost:8080/myApp/mrMoeView/save --post-file=xmltest.xml --header="Content-Type:application/xml"

Grails日志(请注意，没有解析的参数，并且主体具有所有xml):

网址映射:

class UrlMappings {

static mappings = {
    "/$controller/$action?/$id?"(parseRequest:true){
        constraints {
            // apply constraints here
        }
    }

    "/"(view:"/index")
    "500"(view:'/error')
}
}

推荐答案

使用内容类型指定的内容将作为请求正文的一部分接收，而不是解析的参数.

With content type specified content will be received as part of request body instead of parsed params.

实际上，可以将其作为request.XML进行访问.通过评论，我们发现使用bindData的旧方法.使用Grails 2.3.*，只要主体具有有效的id:

Body can be accessed as request.XML in action. Going through the comments, we found out the usage of a older way to bindData. With Grails 2.3.*, the request payload can be directly bound to a domain object provided the body has a valid id as :

def save(MyDomain abc){
    //use abc.name
}

如果请求正文中没有有效的ID，则域对象在操作内将为null.

If a valid id is not present in request body then domain object will be null inside the action.

@ 数据绑定.
