【问题描述】:
我知道这必须有一些超级简单的答案,但我只是从这些东西开始并遵循本教程:https://jsreport.net/blog/pdf-reports-in-sql-server
除了它给了我一个空白页作为没有真正错误消息的输出。
我正在使用车把和 chrome-pdf 来执行此操作...
我的数据库连接脚本是:
const sql = require('mssql');
const config = {
"user": "user",
"password": "password",
"server": "server",
"database": "database"
}
async function beforeRender(req, res) {
await sql.connect(config)
const sqlReq = new sql.Request();
const recordset = await sqlReq.query(
`SELECT DBVersion
,MinAppVersion
FROM VersionTbl`
)
Object.assign(req.data, {Versions: recordset });
}
我可以在调试选项卡中看到它正在运行并正确连接...如果我直接在数据库服务器中测试它,我的 sql 查询似乎是正确的。
我的模板如下所示:
<table>
{{#each Version}}
<tr>
<td>{{DBVersion}}</td>
<td>{{MinAppVersion}}</td>
</tr>
{{/each}}
</table>
调试日志...

各位聪明人能告诉我怎么回事吗?谢谢
