    关于APIP

    概述

    APIP(Application Programming Interface Protocols)是自由共识生态协议的一种类型，用于创建和发布开放的API文档，供API服务方开发部署通用API服务，以实现数据服务的去中心化。API需求方可以按照APIP协议从遵循该协议的任何一个API服务方那里获取数据服务。

    通用规则

    《APIP1_OpenAPI》规范了APIP类型协议的协议发布、接口标识、接口URL构成、时间戳格式、密码算法、服务流程、商业模式、连接接口，数据接口和查询语法的通用规则。设计、开发或应用APIP协议前，应先参考《APIP1_OpenAPI》协议。

    建立连接

    使用APIP协议各接口，须先采用《APIP1_OpenAPI》的connect接口从API服务方获取symKey。参见《APIP1_OpenAPI》的“connect接口”。

    通用请求参数

    APIP类型协议接口的通用请求参数如下：

    name type description requested
    requester string 请求方的fch地址 Y
    url string 当前所请求api的url Y
    timestamp timestamp 发起请求的时间戳，精确到毫秒 Y
    query object 请求数据的查询语句，参见”APIP简易查询语法@APIP1“ N
    sort object 请求数据的排序语句，参见”APIP简易查询语法@APIP1“ N
    from int 请求列表数据时的起始位置，从0开始 N
    size int 请求列表数据时的每页条目数 N
    sign string 用symkey对其他参数所做的签名 Y

    通用响应方式

    响应前所作的验证、通用响应状态码、通用响应参数参见《APIP1_OpenAPI》的“数据请求接口”的“5. 响应”。

    请求成功的通用响应参数为：

    参数 类型 说明 适用状态
    code int 响应状态码 all
    message string 响应状态描述 all
    data object 正常返回数据，由具体APIP定义。 0
    sign string 将symKey加入响应参数做两次sha256哈希的签名值 all

    具体APIP协议的特定响应参数在data参数中给出，并定义具体接口的响应状态。

    请求失败的通用响应码、响应信息和响应参数，参见《APIP1_OpenAPI》的“数据请求接口”的“5. 响应”。

    签名与验证

    APIP接口的请求和响应都需要签名和验证。

    connect接口请求时用私钥签名，公钥验证，响应时无需签名。

    所有数据请求和数据响应，采用以下方法：

    签名：将对称密钥symKey加入参数压缩升序后计算两次sha256，得到sign的值，再用sign替换参数中的symKey。

    验证：将sign从参数中取出，加入symKey，压缩升序后做两次sha256计算，将值与sign的值比较，一致则验证通过。

    详见《APIP1_OpenAPI》

    关于本协议

    1. 本协议接口提供链上密信信息。

    2. 本协议接口的数据来源遵循以下协议：

      • 《FEIP7_MailOnChain》

    3. 本协议接口数据采用JSON格式。

    4. 示例数据：

    requester：FEk41Kqjar45fLDriztUDTUkdki7mmcjWK

    requester的公钥pubKey：030be1d7e633feb2338a74a860e76d893bac525f35a5813cb7b21e27ba1bc8312a

    requester的私钥priKey：L2bHRej6Fxxipvb4TiR5bu1rkT3tRp8yWEsUy4R1Zb8VMm2x7sd8

    requester获得的对称密钥symKey：d2c03bbc1ba1380eafc395374e8da61f92545a1aac5d30b0c19289a69bd34a09
