2. 区块链RPC接口

标签:RPC


Java SDK为区块链应用开发者提供了Java API接口,按照功能,Java API可分为如下几类:

  • Client: 提供访问FISCO BCOS 3.x节点JSON-RPC接口支持、提供部署及调用合约的支持;

  • Precompiled: 提供调用FISCO BCOS 3.x Precompiled合约(预编译合约)的接口,主要包括ConsensusServiceSystemConfigServiceBFSServiceKVTableService

  • AuthManager: 提供FISCO BCOS 3.x 权限控制预部署合约的调用。

注解

  • Client接口声明位于 Client.java 文件中

特别注意: 1. Client接口均有两种,一种是带有node的接口,另一种是不带node的接口。带有node的接口可以让节点RPC发送请求到指定已连接的节点。如果不指定,节点RPC则会随机发送请求到节点。 2. 以下接口示例,都是关闭了节点ssl通信的前提下。若要关闭节点的ssl通信配置项,请将节点配置文件config.ini[rpc] 项设置为 disable_ssl=true

1. 合约操作接口

sendTransaction

发送交易到区块链。

参数

  • node:可让RPC发送请求到指定节点

  • signedTransactionData:签名后的交易

  • withProof:返回是否带上默克尔树证明

返回值

  • BcosTransactionReceipt: 节点收到交易后,回复给SDK的回包,包括交易哈希信息。
