extjs4 - 是否有一个非json / xml作者代理？ [英] extjs4 - is there a non json/xml writer for proxies?

问题描述

API依赖于标准POST方法来保存数据。

>

我已经配置了一个模型和代理，直到它将数据推送到服务器上，但似乎只有两个写入器类型，json& xml。

  proxy：{
 / * ... * / 
 reader：{
类型：'json'，
 root：'results'
}，
 writer：{
 type：'???'//<  - 只能看到json或文档中的xml 
} 
} 
  

没有标准POST作者只需在后期字段中提交数据。

我很惊讶，这不是一个标准的作家类型。

（解析json格式不会太难实现，但这意味着更新很多旧的api文件。）

解决方案

好的，我可以通过检查现有作者的源代码来轻松创建该作者。

现有作家能够做的一件事 - 这可能是开发团队只实现一个json和xml版本的原因 - 他们可以一次推多个记录。

这可以在POST中实现，但会更复杂一些。

如果您尝试将单个模型推送到api，此作者将会工作POST：

  Ext.define（'Ext.data.writer.SinglePost'，{
 extend：'Ext。 data.writer.Writer'，
 alternateClassName：'Ext.data.SinglePostWriter'，
 alias：'writer.singlepost'，
 
 writeRecords：function（request，data）{ 
 request.params = data [0]; 
返回请求; 
} 
}）; 
  

，并将其用于代理作者：

 作者：{
类型：'singlepost'
} 
  

I'm building some models to interact with an existing API from a previous project.

The API relies on standard POST methods to save the data.

I've configured a model and proxy up to the point where it does push the data onto the server but there only seems to be two writer types, json & xml.

proxy: {
        /* ... */
        reader: {
            type: 'json',
            root: 'results'
        },
        writer: {
            type: '???' // <-- can only see json or xml in the docs
        }
    }

Isn't there a standard POST writer that simply submits data in post fields?

I'm surprised that wouldn't be a standard writer type.

(Parsing the json format wouldn't be too hard to implement but that would mean updating a lot of the old api files.)

解决方案

Ok, I was able to create that writer quite easily by checking the existing writers' source code.

One thing those existing writers are able to do - and that may be why the dev team only implemented a json and xml version - is that they can push multiple records at once.

That could be implemented in POST but would be a bit more complicated.

This writer will work if you're trying to push a single model to an api using POST:

Ext.define('Ext.data.writer.SinglePost', {
    extend: 'Ext.data.writer.Writer',
    alternateClassName: 'Ext.data.SinglePostWriter',
    alias: 'writer.singlepost',

    writeRecords: function(request, data) {
        request.params = data[0];
        return request;
    }
});

and the use this for the writer in the proxy:

writer: {
            type: 'singlepost'
        }
