示例1: createUser

// get a user repository to perform operations with user
const userRepository: Repository<User> = getManager().getRepository(User);
// build up entity user to be saved
const userToBeSaved: User = new User();
userToBeSaved.name = ctx.request.body.name;
userToBeSaved.email = ctx.request.body.email;
// validate user entity
const errors: ValidationError[] = await validate(userToBeSaved); // errors is an array of validation errors
if (errors.length > 0) {
// return bad request status code and errors array
ctx.status = 400;
ctx.body = errors;
} else {
// save the user contained in the POST body
const user = await userRepository.save(userToBeSaved);
// return created status code and updated user
ctx.status = 201;
ctx.body = user;
}
}示例2: getUsers
public static async getUsers (ctx: BaseContext) {

}
}示例4: updateUser
public static async updateUser (ctx: BaseContext) {
// get a user repository to perform operations with user
const userRepository: Repository<User> = getManager().getRepository(User);
// check if a user with the specified id exists
