我正在寻找一个命令行实用程序,至少会以人类可读的形式呈现二进制原型数据.过滤和选择选项(沿着文本的切割线)将是很好的,但主要目的是使数据可见以用于调试目的.
如果没有确定的工具,链接到相关的包是正确的.
协议编译器 – protoc – 通过–decode和–decode_raw标志内置此功能.这是用于从.proto文件生成代码的相同工具,因此可能已经安装.
例如：
protoc --decode_raw < message.bin
或使用.proto文件：
protoc --decode mypkg.MyType myschema.proto < message.bin
这是–help文字：
Usage: protoc [OPTION] PROTO_FILES
Parse PROTO_FILES and generate output based on the options given:
-IPATH,--proto_path=PATH Specify the directory in which to search for
imports. May be specified multiple times;
directories will be searched in order. If not
given,the current working directory is used.
--version Show version info and exit.
-h,--help Show this text and exit.
--encode=MESSAGE_TYPE Read a text-format message of the given type
from standard input and write it in binary
to standard output. The message type must
be defined in PROTO_FILES or their imports.
--decode=MESSAGE_TYPE Read a binary message of the given type from
standard input and write it in text format
to standard output. The message type must
be defined in PROTO_FILES or their imports.
--decode_raw Read an arbitrary protocol message from
standard input and write the raw tag/value
pairs in text format to standard output. No
PROTO_FILES should be given when using this
flag.
-oFILE,Writes a FileDescriptorSet (a protocol buffer,--descriptor_set_out=FILE defined in descriptor.proto) containing all of
the input files to FILE.
--include_imports When using --descriptor_set_out,also include
all dependencies of the input files in the
set,so that the set is self-contained.
--include_source_info When using --descriptor_set_out,do not strip
SourceCodeInfo from the FileDescriptorProto.
This results in vastly larger descriptors that
include information about the original
location of each decl in the source file as
well as surrounding comments.
--error_format=FORMAT Set the format in which to print errors.
FORMAT may be 'gcc' (the default) or 'msvs'
(Microsoft Visual Studio format).
--print_free_field_numbers Print the free field numbers of the messages
defined in the given proto files. Groups share
the same field number space with the parent
message. Extension ranges are counted as
occupied fields numbers.
--plugin=EXECUTABLE Specifies a plugin executable to use.
Normally,protoc searches the PATH for
plugins,but you may specify additional
executables not in the path using this flag.
Additionally,EXECUTABLE may be of the form
NAME=PATH,in which case the given plugin name
is mapped to the given executable even if
the executable's own name differs.
--cpp_out=OUT_DIR Generate C++ header and source.
--java_out=OUT_DIR Generate Java source file.
--python_out=OUT_DIR Generate Python source file.
