Question

我尝试使用ExtJS5.1.2作为前端来替换Flex3 UI。
我听说ExtJS可以使用AMF。我测试过从ExtJS调用AMF，它很成功。

我预计它会返回与AMF + Flex3相同的响应。但它没有。它从ExtJS调用的响应比Flex更慢，更重。

我测试的内容： 从Oracle DB获取10000条记录并在DataGrid中显示。

数据大小： 13.1MB（ExtJS的） 2.6MB（Flex3）

我在Firebug看到了回复。
二进制响应很混乱，但看起来数据结构不同。

ExtJS5.1.2中的

每个记录都出现了字段名称。

问题： 尽管两者都呼叫相同的AMF，为什么响应不同？如果可能的话，我需要像Flex + AMF这样的轻量级响应。

非常感谢任何帮助。

我使用的是Ext JS 5.1.2，BlazeDS3，Tomcat6，Adobe Flex3.4。

更新日期：Nov 04 16:05（JST）
我已经阅读了Ext.direct.AmfRemotingProvider的源代码并发现了这一点。

if (me.binary) {
    encoder = new Ext.data.amf.Encoder( {format: 0}); // AMF message sending always uses AMF0   Here!!
    // encode packet
    encoder.writeAmfPacket(amfHeaders, amfMessages);
    request.binaryData = encoder.bytes;
    request.binary = true; // Binary response
    request.headers = {'Content-Type': 'application/x-amf'};
} else {
    encoder = new Ext.data.amf.XmlEncoder();
    // encode packet
    encoder.writeAmfxRemotingPacket(amfMessages[0]);
    request.xmlData = encoder.body;
}

AmfRemotingProvider使用 AMF0 说实话，我不太了解AMF0和AMF3之间的区别。无论如何，我怀疑并研究如何使用ExtJS中的AMF3。

常见的Java代码

    String w_sql = "";

    try {
        w_sql = "SELECT A.* FROM APR361 A WHERE ROWNUM<10001";

        c = ConnectionHelper.getConnection();
        ps = c.prepareStatement(w_sql);

        rs = ps.executeQuery();

        while (rs.next()) {

我试图使用Node.js＆amp; node-oracledb驱动程序使用gzip压缩而不是使用AMF＆amp; BlazeDS的。响应数据大小为900KB！

ExtJS + Node.js（900KB）vs Flex3 + AMF3（2.6MB）

从ExtJS调用的AMF响应数据结构与从Flex
