JS 期望回调值

Question

我给 Frida 写了这个 JS 脚本

function find_func_address(lib,func)
{

    Module.enumerateExports(lib,
            {onMatch:
                
                function(f){if(f.name==func){
                    console.log("address: " + f.address);}
                    return new NativePointer(f.address);
                
                
            }});
            
}


Interceptor.attach(find_func_address("lib.so","myFunc"), {
    onEnter: function (args) {  
        console.log("enter");
    },
    onLeave: function(retval) {
    
        console.log("exit");
    }
});

但是我收到错误：错误：预期回调值在线：

Interceptor.attach(find_func_address("lib.so","myFunc"), {

这是为什么？

你需要添加：

onComplete：函数（）{}

代码完成：

function find_func_address(lib,func)
{

    Module.enumerateExports(lib,
            {onMatch:
                
                function(f){if(f.name==func){
                    console.log("address: " + f.address);}
                    return new NativePointer(f.address);
                
                
            }})            
}


Interceptor.attach(find_func_address("lib.so","myFunc"), {
    onEnter: function (args) {  
        console.log("enter");
    },
    onLeave: function(retval) {
    
        console.log("exit");
    },
    onComplete: function() {}

});
