deftype's Issues

[server-rust]Json库 serde_json 替代 rustc_serialize

[web] 用户登录

• 用户名密码登录
• token session-storage
• 注销

[server-rust]用户密码Bcrypt化

[server-rust]引入websocket

选型：

• housleyjk/ws-rs

[server-rust]重构掉全局变量？

conn_pool
server_config

[server-rust]Serve Static

[web]引入webpack,react,typescript?

• webpack
• react
• typescript

[server-rust]ResultDTO 数据类型

• 类型定义

#[derive(Serialize, Debug)]
pub struct ResultDTO<T: ser::Serialize> {
    pub ok: bool,
    pub code: i32,
    pub message: String,
    pub data: T,
}

impl<T: ser::Serialize> ResultDTO<T> {
    pub fn ok(data: T) -> Self {
        ResultDTO {
            ok: true,
            code: 0,
            data: data,
            message: "".to_owned(),
        }
    }

    pub fn err(data: T) -> Self {
        ResultDTO {
            ok: false,
            code: 1,
            data: data,
            message: "".to_owned(),
        }
    }

    #[allow(dead_code)]
    pub fn code(mut self, value: i32) -> Self {
        self.code = value;
        self
    }

    #[allow(dead_code)]
    pub fn message(mut self, message: &str) -> Self {
        self.message = message.to_owned();
        self
    }
}

ext:

impl<T: ser::Serialize> ResultDTO<T> {
    pub fn to_json_result(&self) -> IronResult<Response> {
        json(self)
    }
}

[server-rust]服务器端数据校验

[server-rust]整合数据库操作

• 整合PostgreSQL
  • 数据库初始化脚本
• 整合diesel https://github.com/sgrif/diesel
  • 整合
  • 连接
  • 数据迁移

[server-rust]支持JWT认证授权

• MAC-sha256
• login
• filter(middleware)

[server-rust]Db操作错误类型

• 定义 DbError

  UpdateError ,QueryError, SaveError, Delete Error ?

• 修改 models api返回为类型为 Result<T, DBError>

• DBError 与IronError适配

[server-rust]User Manager

1. bcrypt加密强度降低 2016-02-27

   static MIN_COST: u32 = 4;
   static MAX_COST: u32 = 31;
   pub static DEFAULT_COST: u32 = 12;

   cost >= MIN_CONST && cost <= MAX_COST

   目前使用cost = 4

2. change password

[server-rust]handle 500

[server-rust]类似LiveReload 支持

• 开发模式下通过http 暴露 pid

[server-rust]Json body-parser

let parsed = req.get::<bodyparser::Struct<models::NewUser>>();
let parsed = try!(parsed.map_err(|err| CustomBodyError { cause: err }));
match parsed {
    Some(ref new_user) => json(&models::create_user(&models::establish_connection(), new_user)),
    None => json(&"".to_owned()),
}

[server-rust]Run Mode支持

$ RUN_MODE=production cargo run --release

[server-rust]支持HTTPS

[server-rust]Bin tools 引入命令行参数解析工具clap-rs

• https://github.com/kbknapp/clap-rs

[server-rust]判断是否为Ajax请求

header! { (XMLHttpRequest, "X-Requested-With") => [String] }

#[allow(dead_code)]
pub fn is_ajax_request(req: &Request) -> bool {
    req.headers.has::<XMLHttpRequest>()
}

[server-rust]handle 404

[server-rust]Content Negotiation for error processing

1. json
2. html

[server-rust]Runtime middleware

[server-rust]使上数据库连接池

impl:

use std::env;
use r2d2;
use r2d2_diesel::ConnectionManager;
use dotenv::dotenv;
use diesel::pg::PgConnection;

lazy_static! {
    pub static ref POOL: r2d2::Pool<ConnectionManager<PgConnection>> = make_pool();
}

pub fn conn_pool<'a>() -> &'a r2d2::Pool<ConnectionManager<PgConnection>> {
    &(*POOL)
}

fn make_pool() -> r2d2::Pool<ConnectionManager<PgConnection>> {
    dotenv().ok();

    let config = r2d2::Config::default();
    let manager = ConnectionManager::<PgConnection>::new(env::var("DATABASE_URL")
                                                             .expect("DATABASE_URL must be set"));

    r2d2::Pool::new(config, manager).expect("Failed to create pool.")
}

How to use:

let conn = try!(global::conn_pool().get().map_err(GetTimeoutWrapper));
json(&models::create_user(&conn, new_user))

[server-rust]Bcrypt命令行工具
