Malicious npm Packages Inject SSH Backdoors via Typosquatted Libraries
Socket’s threat research team has detected six malicious npm packages typosquatting popular libraries to insert SSH backdoors.
emock-service
Advanced tools
emock-service提供模拟REST API服务,仅通过一些简单逻辑,就可以实现一个比较『完整、真实』的后端。在前后端分离开发的项目中,帮助前端人员快速开发。
npm install emock-service
项目下新建db.json
文件,增加以下内容:
{
"users": [
{
"id": 1,
"name": "jack"
},
{
"id": 2,
"name": "rose"
}
]
}
import {server} from 'emock-service';
let options = {
source: 'db.json',
host: '127.0.0.1',
port: 3000
};
server(options);
emock-service自动生成以下服务:
GET /users
支持任意字段排序、分页、全字段搜索
desc
、asc
GET /users/:id
POST /users
PUT /users/:id
DELETE /users/:id
浏览器地址栏输入http://127.0.0.1:3000/users
,可看到如下结果:
emock-service可根据实体的json schema定义自动生成测试数据,目前json schema需满足以下要求:
.json
id
标识资源名称(待改进,json schema规范中id为当前json schema的资源标识符)faker, chance
mock-service使用json-schema-faker生成实体数据,因此,需要在json schema的字段定义中引入faker, chance,调用fakerjs/chancejs
对应的方法随机生成数据。
{
"id": "user",
"type": "object",
"properties": {
"name": {
"type": "string",
"maxLength": "100",
"minLength": "2",
"faker": "name.findName"
}
},
"required": ["name"]
}
Notes: json schema中无需定义id
,emock-service会生成唯一的id。
修改server启动配置:
import {server} from 'emock-service';
let options = {
source: 'db.json',
host: '127.0.0.1',
port: 3000,
// 自动生成数据使用的json schema所在路径
schemaDir: 'path/to/schemas',
// 为每个资源自动生成的数据条数,默认值10
count: 20
};
server(options);
资源之间一般存在关联关系,json schema不能描述资源之间的这种关系,缺少关联关系可能导致自动生成的数据不可用。因此emock-service了一种描述简单关联关系的方法,具体参见示例:
export default {
user: {
companyId: {
resource: 'company',
field: 'id'
},
companyIds: {
resource: 'company',
field: 'id'
},
}
};
上述对象表达的关联关系为:
import {server} from 'emock-service';
import relations from './relations';
let options = {
source: 'db.json',
host: '127.0.0.1',
port: 3000,
// 自动生成数据使用的json schema所在路径
schemaDir: 'path/to/schemas',
// 为每个资源自动生成的数据条数,默认值10
count: 20,
relations: relations
};
server(options);
自定义route中可以使用lowdb实例,个性化处理请求。
import {server} from 'emock-service';
let options = {
source: 'db.json',
host: '127.0.0.1',
port: 3000,
// 自动生成数据使用的json schema所在路径
schemaDir: 'path/to/schemas',
// 为每个资源自动生成的数据条数,默认值10
count: 20,
routes: [
{
url: '/api/js/users/verify',
method: 'GET',
handler(db, req, res, next) {
}
}
]
};
server(options);
其中req、res为express中的request/response实例,如何使用可参考express文档;
db为lowdb实例,lowdb实例上有lodash API,可以借助lodash api便利的操作集合,lowdb文档。
import {server} from 'emock-service';
let options = {
source: 'db.json',
host: '127.0.0.1',
port: 3000,
// 自动生成数据使用的json schema所在路径
schemaDir: 'path/to/schemas',
// 为每个资源自动生成的数据条数,默认值10
count: 20,
pluralOverrides: {
list(db, name, request, response, next) {},
get(db, name, request, response, next) {},
create(db, name, request, response, next) {},
update(db, name, request, response, next) {},
delete(db, name, request, response, next) {}
}
};
server(options);
参数说明:
有些常量数据,无法或者不需要使用json schema生成,可将其放在一个json文件中,emock-server启动时,从该文件中读取数据,copy到数据库。
为所有自动生成的api增加urlPrefix
前缀。
