c++：LLDB + Python -如何在python脚本中打印std::string

import lldb

def print_std_string(debugger, command, result, internal_dict):
    # 获取std::string对象的地址
    std_string_address = debugger.GetSelectedTarget().EvaluateExpression(command).GetValueAsUnsigned()

    # 获取std::string对象的长度
    length = debugger.GetSelectedTarget().EvaluateExpression('(int)(' + command + ').length()').GetValueAsUnsigned()

    # 读取std::string对象的内容
    process = debugger.GetSelectedTarget().GetProcess()
    error = lldb.SBError()
    buffer = process.ReadMemory(std_string_address, length, error)

    # 将内容转换为字符串并打印
    if error.Success():
        result.AppendMessage(buffer.GetString())
    else:
        result.AppendMessage('Failed to read std::string')

# 注册LLDB命令
def __lldb_init_module(debugger, internal_dict):
    debugger.HandleCommand('command script add -f print_std_string.print_std_string print_std_string')

(lldb) print_std_string my_string
