Bmob 后端云

使用 Bmob 后端云，不用自己写 API 接口，只需要定义数据表及相关字段即可实现用户注册、登录、修改用户信息功能。
具体怎么创建应用，大家看官网介绍就行，这里简单说下数据表。

创建应用后，应用中的云数据库默认存在一个用户表_User，且相应的存在一些默认字段，如：帐号username，密码password，手机号mobilePhoneNumberVer/mobilePhoneNumber，邮箱emailVerified；我们开发者可以自定义往里添加需要的字段，如：昵称nickName。

在这里插入图片描述

代码示例
1、注册

/// 注册
+ (void)registerWithName:(NSString *)name password:(NSString *)password parameter:(NSDictionary *)dict complete:(void (^)(BOOL success, NSError *error))complete
{
    BmobUser *user = [[BmobUser alloc] init];
    [user setUsername:name];
    [user setPassword:password];
    [dict enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull obj, BOOL * _Nonnull stop) {
        [user setObject:obj forKey:key];
    }];
    [user signUpInBackgroundWithBlock:^(BOOL isSuccessful, NSError *error) {
        if (complete) {
            complete(isSuccessful, error);
        }
    }];
}

运行示例

[UserModel registerWithName:@"devZhang" password:@"123456" parameter:@{ @"nickName":@"番薯大佬"} complete:^(BOOL success, NSError * _Nonnull error) { 
    NSLog(@"success %@, error = %@", @(success), error.description);
}];
------------------------------------------------        
success 1, error = (null)

2、登录

/// 登录
+ (void)loginWithName:(NSString *)userName password:(NSString *)password complete:(void (^)(BmobUser *user, NSError *error))complete
{ 
    [BmobUser loginWithUsernameInBackground:userName password:password block:^(BmobUser *user, NSError *error) { 
        if (complete) { 
            complete(user, error);
        }
    }];
}

运行示例

[UserModel loginWithName:@"devZhang" password:@"123456" complete:^(BmobUser * _Nonnull user, NSError * _Nonnull error) { 
    NSLog(@"user %@, error = %@", user, error.description);
}];
------------------------------------------------        
user 
className = _User;
username = devZhang;
mobilePhoneNumber = (null);
email = (null);
objectId = 2bb9f3db62;
createdAt = 2020-02-09 02:40:45 +0000;
updatedAt = 2020-02-09 02:40:45 +0000;
data = { 
    createdAt = "2020-02-09 10:40:45";
    nickName = "\U756a\U85af\U5927\U4f6c";
    username = devZhang;
};

3、修改用户信息

/// 修改用户信息
+ (void)modifyWithParameter:(NSDictionary *)dict complete:(void (^)(BOOL success, NSError *error))complete
{ 
    BmobUser *user = UserModel.user;
    if (user == nil) { 
        if (complete) { 
            NSError *error = [NSError errorWithDomain:NSCocoaErrorDomain code:-1 userInfo:@{ @"message":@"用户不存在"}];
            complete(NO, error);
        }
        return;
    }
    [dict enumerateKeysAndObjectsUsingBlock:^(id  _Nonnull key, id  _Nonnull obj, BOOL * _Nonnull stop) { 
        [user setObject:obj forKey:key];
    }];
    [user updateInBackgroundWithResultBlock:^(BOOL isSuccessful, NSError *error) { 
        if (complete) { 
            complete(isSuccessful, error);
        }
    }];
}

运行示例

[UserModel modifyWithParameter:@{ @"nickName":@"大番薯"} complete:^(BOOL success, NSError * _Nonnull error) { 
    NSLog(@"success %@, error = %@", @(success), error.description);
}];
------------------------------------------------    
success 1, error = (null)

4、获取当前用户信息

/// 当前用户
+ (BmobUser *)user
{ 
    BmobUser *user = [BmobUser currentUser];
    return user;
}

运行示例

BmobUser *user = UserModel.user;
NSLog(@"user %@", user);
------------------------------------------------
user 
className = _User;
username = devZhang;
mobilePhoneNumber = (null);
email = (null);
objectId = 2bb9f3db62;
createdAt = 2020-02-09 02:40:45 +0000;
updatedAt = 2020-02-09 02:42:02 +0000;
data = { 
    createdAt = "2020-02-09 10:40:45";
    nickName = "\U5927\U756a\U85af";
    updatedAt = "2020-02-09 10:42:02";
    username = devZhang;
};
