我与how-to-use-moment-js-library-in-angular-2-typescript-app中采用的方法非常相似,但仍然得到private void btnEkle_Click(object sender, EventArgs e)
{
baglan.Open();
SqlCommand cmd = new SqlCommand("INSERT INTO uyeler (uye_adi,uye_soyadi,uye_yasi,uye_adresi,uye_telefonu,uye_mailadresi) values ('@uye_adi','@uye_soyadi','@uye_yasi','@uye_adresi','@uye_telefonu','@uye_mailadresi')",baglan);
cmd.Connection = baglan;
cmd.Parameters.AddWithValue("@uye_adi",textAd.Text);
cmd.Parameters.AddWithValue("@uye_soyadi",textSoyad.Text);
cmd.Parameters.AddWithValue("@uye_yasi",textYas.Text);
cmd.Parameters.AddWithValue("@uye_adresi",textAdres.Text);
cmd.Parameters.AddWithValue("@uye_telefonu",textTelefon.Text);
cmd.Parameters.AddWithValue("@uye_mailadresi",textMail.Text);
cmd.ExecuteNonQuery();
baglan.Close();

}
error TS2307: Cannot find module 'mqtt'.
没有找到打字但这确实......
npm install --save mqtt
<s>typings install --save mqtt</s
我的tsconfig.conf看起来像这样
typings install mqtt --save --ambient
和{
"compilerOptions": {
"noImplicitAny": true,
"module": "commonjs",
"target": "ES5",
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"sourceMap": true,
"declaration": true
},
"files": [
"ng2-mqtt.ts"
],
"exclude": [
"node_modules"
]
}
就是这个......
ng2-mqtt.ts
和export * from './src/mqtt.service'
有..
./src/mqtt.service.ts
tsc -version 1.8.10,angular2 @2.0.0-beta.17,typings 0.8.1,npm 2.14.20,node v4.4.1,Windows 7
将Angular 2与其打字世界之外的元素一起使用会不会太难?
答案 0 :(得分:2)
我做了以下工作让我的工作:
1)首先通过package.json在依赖项中安装ng2-mqtt并运行npm update,以便在node_modules
中使用它2)在index.html中,请务必包含它:
<html>
<head>
<title>whatever</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="node_modules/bootstrap/dist/css/bootstrap.css">
<script>document.write('<base href="' + document.location + '" />');</script>
<script src="node_modules/ng2-mqtt/mqttws31.js" type="text/javascript"></script>
3)将mqtts映射添加到systemjs.config.js(参见map):
System.config({
transpiler: 'typescript',
typescriptOptions: {emitDecoratorMetadata: true},
map: {
'@angular': 'node_modules/@angular',
'mqttws31': 'node_modules/ng2-mqtt/mqttws31.js'
},
4)像往常一样导入:
import {Paho} from 'mqttws31'
5)在@Component中使用它:
this.client = new Paho.MQTT.Client("localhost", Number(61614), "myclientid_");
this.client.onConnectionLost = (responseObject: Object) => {
console.log('Connection lost.');
this.connected ="false";
};
this.client.onMessageArrived = (message: Paho.MQTT.Message) => {
console.log('Message arrived.');
this.msg =message.payloadString;
};
this.client.connect({ onSuccess: this.onConnected.bind(this); });
如果一切顺利,你应该看到你的连接(假设activemq): img
