调用示例
终端调用
curl -X POST \ -H "Content-Type: application/json" \ --data '{ "jsonrpc": "2.0", "method": "Filecoin.Version", "params": [], "id": 1 }' \ http://127.0.0.1:1234/rpc/v0postman调用
http://127.0.0.1:1234/rpc/v0 参数 body raw {"jsonrpc":"2.0","method":"Filecoin.Version","params":[],"id":1} 返回值 {"jsonrpc":"2.0","result":{"Version":"0.5.4+git.d4fef1b5.dirty","APIVersion":3072,"BlockDelay":30},"id":1}lotus代码地址 node/impl/common/common.go
func (a *CommonAPI) Version(context.Context) (api.Version, error) { return api.Version{ Version: build.UserVersion(), APIVersion: build.APIVersion, BlockDelay: build.BlockDelaySecs, }, nil }主要说明lotus rpc的代码实现，以及除了上述网站所写的其他rpc接口
代码路径 cmd/lotus/rpc.go
func serveRPC(a api.FullNode, stop node.StopFunc, addr multiaddr.Multiaddr, shutdownCh <-chan struct{}) error { rpcServer := jsonrpc.NewServer() rpcServer.Register("Filecoin", apistruct.PermissionedFullAPI(a)) ah := &auth.Handler{ Verify: a.AuthVerify, Next: rpcServer.ServeHTTP, } http.Handle("/rpc/v0", ah) }apistruct.PermissionedFullAPI(a) api/apistruct/struct.go //这里相当于包装了一下，添加了权限要求
func PermissionedFullAPI(a api.FullNode) api.FullNode { var out FullNodeStruct auth.PermissionedProxy(AllPermissions, DefaultPerms, a, &out.Internal) auth.PermissionedProxy(AllPermissions, DefaultPerms, a, &out.CommonStruct.Internal) return &out }rpcServer.Register(“Filecoin”, apistruct.PermissionedFullAPI(a)) go-sonrpc 包， 内部使用反射 namespace+"."+method.Name
func (s *RPCServer) register(namespace string, r interface{}) { val := reflect.ValueOf(r) //TODO: expect ptr for i := 0; i < val.NumMethod(); i++ { method := val.Type().Method(i) funcType := method.Func.Type() hasCtx := 0 if funcType.NumIn() >= 2 && funcType.In(1) == contextType { hasCtx = 1 } ins := funcType.NumIn() - 1 - hasCtx recvs := make([]reflect.Type, ins) for i := 0; i < ins; i++ { recvs[i] = method.Type.In(i + 1 + hasCtx) } valOut, errOut, _ := processFuncOut(funcType) // s.methods[namespace+"."+method.Name] = rpcHandler{ paramReceivers: recvs, nParams: ins, handlerFunc: method.Func, receiver: val, hasCtx: hasCtx, errOut: errOut, valOut: valOut, } } }上面代码中可看出，a api.FullNode 下面的都是可以调用的，有些上面链接中没有的。 举个例子 GasEstimateGasPremium
//node/impl/full/gas.go GasEstimateGasPremium(_ context.Context, nblocksincl uint64, sender address.Address, gaslimit int64, tsk types.TipSetKey) (types.BigInt, error)参数 除context外，有四个参数，基本参数好理解，第四个参数 types.TipSetKey是参考上面链接中弄出来的格式
{ jsonrpc: "2.0", method: "Filecoin.GasEstimateGasPremium", params: [ 2, "改成你的地址", 1, [ { /: "随便找个区块的消息ID，hash即可" } ] ], id: 1 } {"jsonrpc":"2.0","result":"1","id":1}
