引言
之前我们已经说过了、NFT.Storage是一个基于IPFS的分布式存储服务，专门用于存储和管理非同质化代币（NFT）相关的数据和资产。它是由Protocol Labs和Pinata共同推出的服务。今天我们基于nft.storage为列、使用java对接打通这个ipfs分布式存储系统。
展开之前也可以看之前对IFPS的基本介绍《IPFS分布式存储系统》、相信对你更加有帮助。
一、nft.storage操作（必读）
注意：要使用科学上网
- 1.1首先我们打开之后官网是这样子的
- 1.2创建项目私钥，到时候对接api需要
官方指引：https://app.nft.storage/v1/docs/intro
- 1.3注意api对接官方有QPS限制要求，
二、java对接
首先引入核心依赖pom
