这条路行不通,那还有一条:把 Python 代码转换成 Native 代码块,Java 通过 JNI 的接口形式调用。 Python -> Native 代码 整体思路 先将Python 源代码转换成 C 代码,之后用 GCC 编译 C 代码为二进制模块 so/dll,接着进行一次 Java Native 接口封装,使用 Jar 打包命令转换成 Jar 包,然后 Java 便可以直接调...

call(["/bin/sh","-i"]);' 这种通过-c参数只能执行相对简单的代码,如果出现了一些自定义函数,要序列化的对象就成了code类型。 但是pickle不能序列化code对象,这里简单测试一下:将要执行的代码都写到一个函数里foo(),尝试反序列化代码对象: 问题解决:从python2.6起,包含了一个可以序列化code对象的模块Marshal...
