python解析.pyd文件的详细代码

有的时候，为了对python文件进行加密，会把python模块编译成.pyd文件，供其他人调用。拿到一个.pyd文件，在没有文档说明的情况下，可以试试查看模块内的一些函数和类的用法。

首先 import XXX（pyd的文件名)

然后直接

print(dir(XXX))

print(help(xxx))

其中dir( ) 列出了属性和方法

而hlep()直接列出了其中的函数以及参数，并且是源码的函数名和类型，非常直观。

例如我这里的一个例子，输出如下：

[\'RC\', \'__doc__\', \'__file__\', \'__loader__\', \'__name__\', \'__package__\', \'__spec__\', \'call_func\', \'collision_recover\', \'disable_robot\', \'drag_mode_enable\', \'enable_robot\', \'get_analog_input\', \'get_analog_output\', \'get_collision_level\', \'get_current_line\', \'get_digital_input\', \'get_digital_output\', \'get_joint_position\', \'get_loaded_program\', \'get_payload\', \'get_program_state\', \'get_rapidrate\', \'get_robot_state\', \'get_sdk_version\', \'get_tcp_position\', \'get_tool_id\', \'get_user_frame_id\', \'is_extio_running\', \'is_in_collision\', \'is_in_drag_mode\', \'is_in_pos\', \'is_on_limit\', \'jog\', \'jog_stop\', \'joint_move\', \'kine_forward\', \'kine_inverse\', \'linear_move\', \'login\', \'logout\', \'power_off\', \'power_on\', \'program_abort\', \'program_load\', \'program_pause\', \'program_resume\', \'program_run\', \'quaternion_to_rot_matrix\', \'rot_matrix_to_quaternion\', \'rot_matrix_to_rpy\', \'rpy_to_rot_matrix\', \'servo_j\', \'servo_move_enable\', \'servo_p\', \'set_analog_output\', \'set_collision_level\', \'set_digital_output\', \'set_error_handler\', \'set_payload\', \'set_rapidrate\', \'set_tool_data\', \'set_tool_id\', \'set_user_frame_data\', \'set_user_frame_id\', \'shut_down\', \'torque_control_enable\', \'torque_feedforward\']
