Extjs 4.2:如何在 Ext.Ajax.Request POST 中正确发送参数 [英] Extjs 4.2: How to send parameters properly in a Ext.Ajax.Request POST

问题描述

我必须从我的 ExtJs 脚本中执行 POST 才能从我的数据库中删除某些内容:

Ext.Ajax.request({url: 'deleteRole.html',方法:'POST'，标头:{'Content-Type':'text/html'}，waitTitle: '正在连接',waitMsg: '发送数据...',参数:{角色名": 角色名},范围:这个，成功:收到，失败:function(){console.log('failure');}});

当帖子发送时，我可以在萤火虫中看到字体中的角色名称，但不是参数.我想向您展示另一篇关于用户注册的帖子(用 spring:form 制作).如果我检查帖子，我可以看到以下内容:

_{(来源:
(来源:subirimagenes.com)}

因此，我的弹簧控制器没有检测到任何参数.我的帖子有问题吗?

谢谢

解决方案

问题是您在使用 headers: {'Content-Type': 'text/html'}, 行你原来的问题.这会将内容设置为 text/html 而不是发布数据的内容.

I have to do a POST from my ExtJs script in order to delete something from my DB:

Ext.Ajax.request({
    url: 'deleteRole.html',
    method: 'POST',          
    headers: {'Content-Type': 'text/html'},
    waitTitle: 'Connecting',
    waitMsg: 'Sending data...',                                     
    params: {
        "rolename" : rolename
    },
    scope:this,
    success: received,                                    
    failure: function(){console.log('failure');}
});

when the post is sent i can see in the firebug the rolename in font but not as a param. I would like to show you another post (made with spring:form) relative to the user registration. If i inspect the post i can see the following:

_{(source: subirimagenes.com)}

And i can get the parameters in my controller using @RequestParam.

But in the post that i have problems i can't see the parameters part, i can only see the Font(Fuente) part:

_{(source: subirimagenes.com)}

As a consequence, my spring controller does not detect any parameter. Is it something wrong in my POST?

Thank you

解决方案

The problem is that you are using the line headers: {'Content-Type': 'text/html'}, in your original question. This would set the content to text/html instead of the content being post data.
