我正在嘗試使用 Google Protocol Buffers 與 Go 中的 C 庫進行通信，但無法使其工作。我在嘗試將 protobuf 發送到 C 庫時遇到錯誤我將發布最小代碼來重現我現在面臨的錯誤（我已刪除了大部分 C 部分，因為它與此錯誤無關）：    /*    #cgo CFLAGS: -I@CURRENT_SOURCE_DIR@/../../library/crnd/include -     I@CMAKE_CURRENT_BINARY_DIR@/../../library    #cgo LDFLAGS: -L@CRND_LIBRARY_PATH@ -lcrnd    #include <api_c.h>    #include <stdint.h>    #include <stdio.h>    #include <inttypes.h>    typedef struct SerializedStruct {        void* data;        int64_t size;    } Serialized;    */    import "C"    func (crnd wrapper) MyFunction() {        // Create a protobuf        sample_request := &messages.SampleRequest { ... add members ...}        fmt.Printf(proto.MarshalTextString(sample_request));  // print the message to check it works        data, err := proto.Marshal(sample_request)        if err != nil {            log.Fatal("marshaling error: ", err)        }        sample_request_serialized := C.Serialized {            data: pointer.Save(data),            size: C.int64_t(len(data)),        }        // Here I would send my protobuf to the C library, but it is not        //  working, so I'm trying to reconstruct the protobuf to check        //  if something is broken before getting to the C side        // Let's reconstruct the protobuf back        data_req := (*[1 << 30]byte)(sample_request_serialized.data)[:int(sample_request_serialized.size):int(sample_request_serialized.size)]        sample_req := &messages.SampleRequest{}        err := proto.Unmarshal(data_req, sample_req)        if err != nil {            log.Fatal("unmarshaling error: ", err)        }    }我收到以下錯誤：unmarshaling error: proto: crnd.SampleRequest: illegal tag 0 (wire type 0)
