抓包商品详情页，要模拟的是sign参数
先搭建基础框架代码：

}
private void destroy() throws IOException{
emulator.close();
System.out.println("destroy");
}
private static LibraryResolver createLibraryResolver() {
return new AndroidResolver(23);
}
private static AndroidEmulator createARMEmulator() {
return AndroidEmulatorBuilder
.for32Bit()
.build();
}
private final AndroidEmulator emulator;
private final VM vm;
private Module module;
private DvmClass aBitmapkitUtils;
//初始化
public jd_main(){
emulator = createARMEmulator();
final Memory memory = emulator.getMemory();
// 设置 sdk版本 23
memory.setLibraryResolver(createLibraryResolver());
//使用apk文件加载so的话，会自动处理签名方面的jni，具体可看AbstractJni,利用apk加载的好处，
vm = emulator.createDalvikVM(new File("F:\\frida_learn_app\\jd\\jd-9.2.2.apk"));
vm.setJni(this);
// 是否打印日志
vm.setVerbose(true);
}
public String runJni(){
//加载apk的so
DalvikModule dm = vm.loadLibrary("jdbitmapkit", false);
//调用jni
dm.callJNI_OnLoad(emulator);
module = dm.getModule();
return null;
}运行有报错补代码
@Override

switch (signature) {
case "com/jingdong/common/utils/BitmapkitUtils->a:Landroid/app/Application;": {

}
}
return super.getStaticObjectField(vm, dvmClass, signature);
}报错补代码

switch (signature) {

if (packageName != null) {
return new StringObject(vm, packageName);
}
}
}
throw new UnsupportedOperationException(signature);
}报错补代码
@Override
public DvmObject<?> newObject(BaseVM vm, DvmClass dvmClass, String signature, VarArg varArg) {
switch (signature) {

return new StringObject(vm, new String(array.getValue()));
}
}
return super.newObject(vm, dvmClass, signature, varArg);
}基础环境没报错后，调用签名函数
//加载so的哪个类
aBitmapkitUtils = vm.resolveClass("com/jingdong/common/utils/BitmapkitUtils");
//调用方法
DvmObject<?> strRc = aBitmapkitUtils.callStaticJniMethodObject(emulator,"getSignFromJni()(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String;",
vm.addLocalObject(null),
vm.addLocalObject(new StringObject(vm,"wareBusiness")),
vm.addLocalObject(new StringObject(vm,"{\"abTest800\":true,\"avoidLive\":false,\"brand\":\"360\",\"cityId\":2144,\"darkModelEnum\":3,\"districtId\":24463,\"eventId\":\"Searchlist_Productid\",\"fromType\":0,\"isDesCbc\":true,\"latitude\":\"26.618816\",\"lego\":true,\"longitude\":\"106.644705\",\"model\":\"1605-A01\",\"ocrFlag\":false,\"pluginVersion\":90220,\"plusClickCount\":0,\"plusLandedFatigue\":0,\"provinceId\":\"24\",\"skuId\":\"10024083045618\",\"source_type\":\"search\",\"source_value\":\"鼠标垫小号\",\"townId\":51707,\"uAddrId\":\"0\"}")),

vm.addLocalObject(new StringObject(vm,"9.2.2")));
System.out.println(strRc.getValue());
//获取返回值
return (String) strRc.getValue();后面有报错也是跟着报错补环境 最后成功运行出结果：

IDEA 找到 File → Project Structure … 然后选择 Artifacts, 点加号 Add 如图配置，勾上 Include tests
点击ok后 Build → Build Artifacts进行编译 编译成功后会生成很多jar文件
在控制台测试运行下 java -jar unidbg-master.jar
运行出了结果，证明打包的没问题

我正在尝试将以下SQL查询转换为ActiveRecord，它正在融化我的大脑。deletefromtablewhereid有什么想法吗？我想做的是限制表中的行数。所以，我想删除少于最近10个条目的所有内容。编辑:通过结合以下几个答案找到了解决方案。Temperature.where('id这给我留下了最新的10个条目。 最佳答案 从您的SQL来看，您似乎想要从表中删除前10条记录。我相信到目前为止的大多数答案都会如此。这里有两个额外的选择:基于MurifoX的版本:Table.where(:id=>Table.order(:id).

我完全不是程序员，正在学习使用Ruby和Rails框架进行编程。我目前正在使用Ruby1.8.7和Rails3.0.3，但我想知道我是否应该升级到Ruby1.9，因为我真的没有任何升级的“遗留”成本。缺点是什么？我是否会遇到与普通gem的兼容性问题，或者甚至其他我不太了解甚至无法预料的问题？ 最佳答案 你应该升级。不要坚持从1.8.7开始。如果您发现不支持1.9.2的gem，请避免使用它们(因为它们很可能不被维护)。如果您对gem是否兼容1.9.2有任何疑问，您可以在以下位置查看:http://www.railsplugins.or
在许多ruby类之间共享记录器实例的最佳(正确)方法是什么？现在我只是将记录器创建为全局$logger=Logger.new变量，但我觉得有更好的方法可以在不使用全局变量的情况下执行此操作。如果我有以下内容:moduleFooclassAclassBclassC...classZend在所有类之间共享记录器实例的最佳方式是什么？我是以某种方式在Foo模块中声明/创建记录器还是只是使用全局$logger没问题？ 最佳答案 在模块中添加常量:moduleFooLogger=Logger.newclassAclassBclassC..
