### ✅ 验证清单 - [x] 🔍 我已经搜索过 [现有 Issues](https://github.com/apache/dubbo-go/issues)，确信这不是重复问题 ### 🚀 Go 版本 1.25.6 ### 📦 Dubbo-go 版本 develop ### 🖥️ 服务端配置 _No response_ ### 💻 客户端配置 _No response_ ### 🌐 协议配置 _No response_ ### 📋 注册中心配置 _No response_ ### 💾 操作系统 🍎 macOS ### 📝 Bug 描述 https://github.com/apache/dubbo-go/blob/28fc318c6667f820191bb6670aac27a4378d0712/protocol/jsonrpc/server.go#L156-L157 err一定是nil ### 🔄 重现步骤 向 jsonrpc 端口发送一个 Content-Type 为 text/plain 的请求,例如: curl --location '127.0.0.1:20002/GreetProvider' \ --header 'Content-Type: text/plain' \ --data '{"jsonrpc":"2.0","method":"SayHello","params":["hello","new","jsonrpc"],"id":1650901121}' ### ✅ 预期行为 不panic,可以返回客户端不支持 ### ❌ 实际行为 2026-04-18 01:13:09 WARN jsonrpc/server.go:83 connection{local:127.0.0.1:20002, remote:127.0.0.1:49903} panic error:"invalid memory address or nil pointer dereference", debug stack:goroutine 168 [running]: runtime/debug.Stack() /usr/local/go/src/runtime/debug/stack.go:26 +0x74 dubbo.apache.org/dubbo-go/v3/protocol/jsonrpc.(*Server).handlePkg.func1() /Users/guzemin/go/pkg/mod/dubbo.apache.org/dubbo-go/[email protected]/protocol/jsonrpc/server.go:84 +0x88 panic({0x10258ad00?, 0x1038c87b0?}) /usr/local/go/src/runtime/panic.go:783 +0xec dubbo.apache.org/dubbo-go/v3/protocol/jsonrpc.(*Server).handlePkg(0x14000336500, {0x1028d41b8, 0x140001280c8}) /Users/guzemin/go/pkg/mod/dubbo.apache.org/dubbo-go/[email protected]/protocol/jsonrpc/server.go:156 +0x950 dubbo.apache.org/dubbo-go/v3/protocol/jsonrpc.(*Server).Start.func1.1({0x1028d41b8, 0x140001280c8}) /Users/guzemin/go/pkg/mod/dubbo.apache.org/dubbo-go/[email protected]/protocol/jsonrpc/server.go:248 +0x34 dubbo.apache.org/dubbo-go/v3/protocol/jsonrpc.accept.func1() /Users/guzemin/go/pkg/mod/dubbo.apache.org/dubbo-go/[email protected]/protocol/jsonrpc/server.go:232 +0x88 created by dubbo.apache.org/dubbo-go/v3/protocol/jsonrpc.accept in goroutine 114 /Users/guzemin/go/pkg/mod/dubbo.apache.org/dubbo-go/[email protected]/protocol/jsonrpc/server.go:221 +0x384 ### 💡 可能的解决方案 ```go // 修改前 (server.go:153-161) if contentType != "application/json" && contentType != "application/json-rpc" { setTimeout(conn, httpTimeout) r.Header.Set("Content-Type", "text/plain") if errRsp := sendErrorResp(r.Header, []byte(perrors.WithStack(err).Error())); errRsp != nil { logger.Warnf("sendErrorResp(header:%#v, error:%v) = error:%s", r.Header, perrors.WithStack(err), errRsp) } return } // 修改后 if contentType != "application/json" && contentType != "application/json-rpc" { setTimeout(conn, httpTimeout) r.Header.Set("Content-Type", "text/plain") errMsg := "unsupported content type: " + contentType if errRsp := sendErrorResp(r.Header, []byte(errMsg)); errRsp != nil { logger.Warnf("sendErrorResp(header:%#v, error:%v) = error:%s", r.Header, errMsg, errRsp) } return } ``` 如果社区认可上述修复方案，我可以尽快提交 Pull Request。 -- This is an automated message from the Apache Git Service.
