关于url中传入action参数的问题

sandgia

// 这个案例中为了下载时能给出文件名，自定义了一个.j用于执行下载的get请求，.j请参考"$UI/demo/actions/process/invokeAction/downloadFile.j"
        // 提交前需要进行URL转换，在URL上补足bsessionid等必要信息
        var url = require.toUrl("$UI/demo/actions/process/invokeAction/downloadFile.j?bsessionid=" + this.getContext().getBSessionID());
        // 用get方式传参
        url = url + "&process=" + this.getContext().getCurrentProcess() + "&activity=" + this.getContext().getCurrentActivity() + "&executor=" + this.getContext().getExecutor()
                + "&action=demoDownloadFile" + "&fileName=123.jpg";

        // + "&fileName=" + window.encodeURI($(downloadFileName).val());
        // 弹出下载
        window.open(url);

上面的正常，现在我将 $UI/demo/actions/process/invokeAction/downloadFile 中的内容复制一份为$UI/ERP/BID/Test/process/StaticTest/DD
配置编译路径后可以编译通过，正常使用，然后 创建一个动作和 demoDownloadFile 有相同的返回值excelStream ，
var url = require.toUrl("$UI/ERP/BID/Test/process/StaticTest/DD.j?bsessionid=" + this.getContext().getBSessionID());
        // 用get方式传参
        url = url + "&process=" + this.getContext().getCurrentProcess() + "&activity=" + this.getContext().getCurrentActivity() + "&executor=" + this.getContext().getExecutor()
               
                + "&action=excelStream" + "&fileName=excel.xls" ;
        // + "&fileName=" + window.encodeURI($(downloadFileName).val());
        // 弹出下载
        console.log(url);
        window.open(url);

然后报错：
2020-07-27 08:28:55 action:<?xml version="1.0" encoding="UTF-8"?>
<action process="/ERP/BID/Test/process/StaticTest/staticTestProcess" activity="mainActivity" name="excelStream" executor="" execute-context="" content-type="application/xml"><parameters><parameter name="fileName"><xbiz:simple xmlns:xbiz="http://www.justep.com/xbiz#" type="http://www.w3.org/2001/XMLSchema#String">excel.xls</xbiz:simple></parameter></parameters></action>

action的动作的对应参数是怎么在这个url里面传给动作的？

jishuang

报错的就是action的参数个数不正确，确认action的参数和设置的参数是否匹配

我其实想问的是，x5在解析这个的时候，process、activity、executor 应该不是动作的参数把，然后fileName可以作为动作的参数，但是往后面再加上其他的参数的时候，怎么确保，某些参数是加在action上的，应该不可能不进行区分就直接加把？是不是根据action.m中定义的参数名称进行判断后组合的？  ： url = url + "&process=" + this.getContext().getCurrentProcess() + "&activity=" + this.getContext().getCurrentActivity() + "&executor=" + this.getContext().getExecutor()               
                + "&action=excelStream" + "&fileName=excel.xls" ;

action中自己定义参数啊
