[英]Flutter cloud function call with parameters
I have a flutter app, my code looks like this:我有一个颤振应用程序,我的代码如下所示:
dynamic result = await CloudFunctions.instance.getHttpsCallable(functionName: 'getAllItemsAfterDatetime').call(
<String, dynamic> {"datetime": "1563109861142"}
);
and a JS file:和一个 JS 文件:
exports.getAllItemsAfterDatetime= functions.https.onRequest(async (req, res) => {
if (!mysqlPool) {
mysqlPool = mysql.createPool(mysqlConfig);
}
let datetime = req.body.datetime;
if (datetime == null) datetime = req.query.datetime;
if (datetime == null) datetime = req.params.datetime;
if (datetime == null) datetime = "3100000012120000";
mysqlPool.query('SELECT * FROM items as res WHERE datetime > ' + datetime, (err, results) => {
if (err) {
console.error(err);
res.status(500).send(err);
} else {
res.status(200).send({cnt: res.length, data: JSON.stringify(results)});
}
});
I got allways "3100000012120000", so basically I can't get my datetime param back from mobil.我总是得到“3100000012120000”,所以基本上我无法从 mobil 取回我的日期时间参数。 It is working in browser.它在浏览器中工作。 How to do this in a mobil app?如何在移动应用程序中执行此操作?
req.parameters is the correct word or WHAT? req.parameters 是正确的词还是什么?
Thanks谢谢
UPDATE: The solution更新:解决方案
//from browser
let datetime = req.body.datetime;
//from mobile
if (datetime == null) datetime = req.body.data.datetime;
//if not set
if (datetime == null) datetime = "3100000012120000";
solution was解决方案是
//from browser
let datetime = req.body.datetime;
//from mobile
if (datetime == null) datetime = req.body.data.datetime;
//if not set
if (datetime == null) datetime = "3100000012120000";
