Question

在下面的代码中，我只能看到结束事件发生而不是现场事件。

const Busboy = require('busboy');

module.exports.controller = function(app) {
    app.post('/api', function(req, res) {
        var busboy = new Busboy({ headers: req.headers });
        var formdata = {};
        busboy.on('field', function (fieldname, val) {
            console.log("fieldname : " + fieldname);
            console.log("value : " + val);
            formdata[fieldname] = val;
        });
        busboy.on('finish', function() {
            res.send(formdata);
        });
        req.pipe(busboy);
    });
};

作为回应，我在邮递员处收到{}。这可能会出现什么问题？

我知道这早就该开始了，但是我也遇到了这个问题，然后我意识到我在HTML输入中缺少<Package ... xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities" IgnorableNamespaces="uap mp uap5 rescap"> ... <Capabilities> <rescap:Capability Name="broadFileSystemAccess" /> </Capabilities>字段。

$sql_code = $conn->query($sql_prep);
