uniapp如何編寫含有后端的登錄注冊頁面

 更新時(shí)間：2023年05月23日 09:22:03   作者：極客李華  
uniapp是一個(gè)使用html5標(biāo)準(zhǔn)的,一次開發(fā),可以發(fā)布到安卓,ios,小程序的多端框架,非常方便,下面這篇文章主要給大家介紹了關(guān)于uniapp如何編寫含有后端的登錄注冊頁面的相關(guān)資料,需要的朋友可以參考下

uniapp-含有后端的登錄注冊頁面編寫

創(chuàng)建數(shù)據(jù)庫

數(shù)據(jù)庫結(jié)構(gòu)

表名：user

列名數(shù)據(jù)類型描述
idint自增ID
usernamevarchar用戶名
passwordvarchar密碼
nicknamevarchar昵稱

這個(gè)方案只保留了id、username、password和nickname四個(gè)字段，以最簡單的方式存儲用戶基本信息。需要注意的是，密碼應(yīng)該進(jìn)行安全處理（如加密），避免泄露敏感信息。如果后續(xù)有新增信息需求，則可以隨時(shí)更改表結(jié)構(gòu)，添加相應(yīng)的列即可。

數(shù)據(jù)庫代碼

-- 創(chuàng)建 usertable 數(shù)據(jù)庫
CREATE DATABASE IF NOT EXISTS usertable;

-- 切換至 usertable 數(shù)據(jù)庫
USE usertable;

-- 創(chuàng)建 user 表
CREATE TABLE IF NOT EXISTS user (
  id INT(11) NOT NULL AUTO_INCREMENT,
  username VARCHAR(100) NOT NULL UNIQUE,
  password VARCHAR(100) NOT NULL,
  nickname VARCHAR(100) NOT NULL,
  PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

-- 添加一些測試數(shù)據(jù)
INSERT INTO user (username, password, nickname) VALUES ('user1', 'password1', '張三');
INSERT INTO user (username, password, nickname) VALUES ('user2', 'password2', '李四');
INSERT INTO user (username, password, nickname) VALUES ('user3', 'password3', '王五');

這段SQL代碼用于創(chuàng)建一個(gè)名為user的表格，并且添加了一些簡單的測試數(shù)據(jù)。其中，id列使用了自增主鍵約束，保證數(shù)據(jù)的唯一性。

username列使用了unique約束，確保用戶名的唯一性。請注意，utf8mb4是一種更高效和更通用的字符編碼，支持更廣泛的Unicode字符集，所以它比utf-8更推薦使用。
