Node-RED中連線Mysql資料庫並實現增刪改查的操作

阿新 • • 發佈：2022-04-18

場景

Node-RED中建立靜態網頁和動態網頁內容：

https://blog.csdn.net/BADAO_LIUMANG_QIZHI/article/details/124211653

在上面的基礎上，怎樣實現連線Mysql資料庫並將資料庫中的資料顯示在網頁上，以及執行插入、更新、刪除操作。

實現

1、安裝NodeRED節點

節點管理搜尋node-red-node-mysql,安裝

 

 

安裝成功之後就會有Mysql節點了

 

 

2、資料庫設計一個測試的使用者表

流程設計如下

 

 

編輯function節點，使其執行查詢語句

msg.topic = "SELECT * FROM user";
return msg;

 

 

 

3、編輯Mysql節點

 

 

編輯連線輸入資料庫連線資訊

 

 

4、編輯template節點修改html顯示模板

<html>
    <head>
        <title>使用者</title>
    </head>
    <body>
      <table border="1
 
">
       {{#payload}}
          <tr><td>{{name}}</td><td>{{pass}}</td></tr>
       {{/payload}}
      </table>
    </body>
</html>

 

 

 

5、部署執行訪問

http://127.0.0.1:1880/allUser

 

 

6、查詢流程json資料

7、實現插入操作

新增插入資料的流程設計

 

 

編輯function節點，編輯插入語句

 

 

執行檢視效果

 

 

插入流程json資料

[
    {
        "id": "1d9518ddb606e944",
        "type": "inject",
        "z": "f4a4d8eab7935bc8",

        "props": [
            {
                "p": "payload"
            },
            {

            [
                "fdde79cf9a1b1722"
            ]
        ]
    },
    {
        "id": "fdde79cf9a1b1722",
        "type": "mysql",
        "z": "f4a4d8eab7935bc8",
        "mydb": "51c3503.61936b",
        "name": "",
        "x": 480,
        "y": 380,
        "wires": [
            [
                "5ea56f3eec020d0f"
            ]
        ]
    },
    {
        "id": "5ea56f3eec020d0f",
        "type": "debug",
        "z": "f4a4d8eab7935bc8",

        "active": true,
        "tosidebar": true,
        "console": false,
        "tostatus": false,
        "complete": "payload",

        "statusVal": "",
        "statusType": "auto",
        "x": 630,
        "y": 380,
        "wires": []
    },
    {
        "id": "51c3503.61936b",
        "type": "MySQLdatabase",
        "name": "",
        "host": "127.0.0.1",

        "tz": "",
        "charset": "UTF8",
        "credentials": {}
    }
]

 

8、新增更新語句執行流程設計如下

 

 

模板值可以在字元找那個嵌入運算式或變數。

但是注意的是字串是使用反引號，在Tab上方的按鈕括起，而不是使用單引號括起。

編輯function節點

var id = 3;
var name = 'updateName';
var pass = '5555';
msg.topic = `UPDATE user SET name='${name}',` +
            `pass='${pass}' WHERE id=${id}`;
return msg;

9、設計刪除流程佈局

 

 

編輯template節點

DELETE FROM user WHERE id='{{payload}}'

 

 

 

部署執行檢視效果

 

 

 

 

刪除流程json資料
