前言

• 由于我司私服需要对某些包删除使用，但又不想误删，所以要整个黑名单，在该名单上的包无法下载和搜索。
• 大概看了下，只要维护个黑名单表即可，另外再改点逻辑，对表写个添加，删除，查询接口即可。
• 首先梳理下路由，会走那些控制器，再建个表，写入增删改查。

路由梳理

• 下载包实际上是先查询，查到后走json的tar地址，所以在搜索时先查黑名单，黑名单里的直接返回404

页面搜索

controllers:web:package:search

页面详情

controllers:web:package:show

下载（查询地址后）

controllers:registry:download
controllers:registry:package:save

查询(下载前)

controllers:registry:package:list

建表

• 建表在docs的db.sql里
• 直接再复制个表：

CREATE TABLE IF NOT EXISTS `black_list` (
 `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT COMMENT 'primary key',
 `gmt_create` datetime NOT NULL COMMENT 'create time',
 `gmt_modified` datetime NOT NULL COMMENT 'modified time',
 `name` varchar(214) NOT NULL COMMENT 'pkg name',
 PRIMARY KEY (`id`),
 UNIQUE KEY `uk_name` (`name`),
 KEY `idx_gmt_modified` (`gmt_modified`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='black list info';

• models/index.js中载入model

 BlackList: load("black_list"),

• 新建black_list

"use strict";

module.exports = function (sequelize, DataTypes) {
  return sequelize.define(
    "BlackList",
    {
      name: {
        type: DataTypes.STRING(214),
        allowNull: false,
        comment: "module name",
      },
    },
    {
      tableName: "black_list",
      comment: "module black list",
      indexes: [
        {
          unique: true,
          fields: ["name"],
        },
      ],
      classMethods: {},
    }
  );
};

• controller中添加操作：

"use strict";

var blackListService = require("../../../services/black_list");

exports.addBlackList = function* () {
  var name = this.request.body.name;
  const res = yield blackListService.addBlackList(name);
  this.body = res;
};
exports.getBlackList = function* () {
  var name = this.request.body.name;
  const res = yield blackListService.getBlackList(name);
  if (!res){
     this.body = {
      err: "not found",
    };
  } else {
    this.body = res;
  }
};
exports.deleteBlackList = function* () {
  var name = this.request.body.name;
  const res = yield blackListService.deleteBlackList(name);
  if (res === 1) {
    this.body = {
      success: true,
    };
  } else {
    this.body = {
      success: false,
    };
  }
};

• services中添加操作：

"use strict";

var models = require("../models");
var blacklist = models.BlackList;

exports.getBlackList = function* (name) {
  var rows = yield blacklist.find({
    where: {
      name: name,
    },
  });
  return rows;
};

exports.addBlackList = function* (name) {
  var item = blacklist.build({
    name: name,
  });
  yield item.save();
  return item;
};
exports.deleteBlackList = function* (name) {
  var item = yield blacklist.destroy({
    where: {
      name: name,
    },
  });
  return item;
};

• 添加路由

app.post("/blacklist/addpkg", blackList.addBlackList);
  app.post("/blacklist/deletpkg", blackList.deleteBlackList);
  app.post("/blacklist/getpkg", blackList.getBlackList);

• 此时增删查已经可以了，下面黑名单的直接不给下载就在list查询处返回404即可：

  const blackres = yield blackListService.getBlackList(name);
  if (blackres) {
    this.status = 404;
    return;
  }

• 在搜索时搜到不影响，在详情页面web/package/show增加废弃提示：

  const blackres = yield blackListService.getBlackList(pkg.name);
  if (blackres) {
    pkg.name = pkg.name + "-@已废弃";
  }

• 改造就基本完成了。
• 另外有人提意改写unpublish命令，顺便写一下。
• unpublish在controllers/registry/package/remove.js里加入

var blackListService = require("../../../services/black_list");

...
 yield blackListService.addBlackList(name);
  debug("add blacklist");
  return yield next;
