jsReport xlsx Recipe beforeRender

Question

使用来自 mssql 的数据呈现 XLSX 配方时出现此错误

Error occured - Error during rendering report: Cannot read property 'xl/worksheets/sheet1.xml' of undefined Stak - TypeError: Cannot read property 'xl/worksheets/sheet1.xml' of undefined at Object.add (evalmachine.:176:42) at Object. (evalmachine.:406:17) at Object.eval (eval at createFunctionContext

我已将链接脚本设置为加载数据。示例：

var sql = require('mssql');
var config = {
    "user": "jsreport",
    "password": "password",
    "server": "janblaha-PC\SQLEXPRESS",
    "database": "northwind"
}

function beforeRender(done) {
    sql.connect(config).then(function() {
        var req = new sql.Request();
        return req.query('select count(*) as Count, ShipCountry  from Orders group by ShipCountry').then(function(recordset) {
            request.data = { countries: recordset };
            done();
        });
    }).catch(done);
}

我可以将数据加载到 pdf、html 甚至 html-xlsx 中而不会出现错误。我尝试只使用一个基本的 sheet，我可以在没有脚本的情况下加载它，如下所示。我也尝试过使用 {{#each }} 语句中的数据。我总是得到同样的错误。想知道是否有人尝试过这样做 and/or 如果我需要以不同的方式加载数据。

{{#xlsxAdd "xl/worksheets/sheet1.xml" "worksheet.sheetData[0].row"}}
    <row>
        <c t="inlineStr"><is><t>Hello world</t></is></c>
        <c><v>11</v></c>
    </row>
{{/xlsxAdd}}

{{{xlsxPrint}}}

在 Github 上收到回复：

//old
request.data = { countries: recordset };
//new
Object.assign(request.data, { countries: recordset })

The recipe is passing some additional data to the templating engines processing and you are overwriting them.
