[原创]Frida实现okhttp3.Interceptor
https://bbs.pediy.com/thread-252100.htm
珍惜Any用xposed实现了okhttp3的Interceptor，我这里发一个frida实现okhttp3的Interceptor
function hook_okhttp3() {
Java.perform(function () {
var ByteString = Java.use("com.android.okhttp.okio.ByteString");
var Buffer = Java.use("com.android.okhttp.okio.Buffer");
var Interceptor = Java.use("okhttp3.Interceptor");
var MyInterceptor = Java.registerClass({
name: "okhttp3.MyInterceptor",
implements: [Interceptor],
methods: {
intercept: function (chain) {
var request = chain.request();
try {
console.log("MyInterceptor.intercept onEnter:", request, "\nrequest headers:\n", request.headers());
var requestBody = request.body();
var contentLength = requestBody ? requestBody.contentLength() : 0;
if (contentLength > 0) {
var BufferObj = Buffer.$new();
requestBody.writeTo(BufferObj);
try {
console.log("\nrequest body String:\n", BufferObj.readString(), "\n");
} catch (error) {
try {
console.log("\nrequest body ByteString:\n", ByteString.of(BufferObj.readByteArray()).hex(), "\n");
} catch (error) {
console.log("error 1:", error);
}
}
}
} catch (error) {
console.log("error 2:", error);
}
var response = chain.proceed(request);
try {
console.log("MyInterceptor.intercept onLeave:", response, "\nresponse headers:\n", response.headers());
var responseBody = response.body();
var contentLength = responseBody ? responseBody.contentLength() : 0;
if (contentLength > 0) {
console.log("\nresponsecontentLength:", contentLength, "responseBody:", responseBody, "\n");
var ContentType = response.headers().get("Content-Type");
console.log("ContentType:", ContentType);
if (ContentType.indexOf("video") == -1) {
if (ContentType.indexOf("application") == 0) {
var source = responseBody.source();
if (ContentType.indexOf("application/zip") != 0) {
try {
console.log("\nresponse.body StringClass\n", source.readUtf8(), "\n");
} catch (error) {
try {
console.log("\nresponse.body ByteString\n", source.readByteString().hex(), "\n");
} catch (error) {
console.log("error 4:", error);
}
}
}
}
}
}
} catch (error) {
console.log("error 3:", error);
}
return response;
}
}
});
var ArrayList = Java.use("java.util.ArrayList");
var OkHttpClient = Java.use("okhttp3.OkHttpClient");
console.log(OkHttpClient);
OkHttpClient.$init.overload('okhttp3.OkHttpClient$Builder').implementation = function (Builder) {
console.log("OkHttpClient.$init:", this, Java.cast(Builder.interceptors(), ArrayList));
this.$init(Builder);
};
var MyInterceptorObj = MyInterceptor.$new();
var Builder = Java.use("okhttp3.OkHttpClient$Builder");
console.log(Builder);
Builder.build.implementation = function () {
this.interceptors().clear();
//var MyInterceptorObj = MyInterceptor.$new();
this.interceptors().add(MyInterceptorObj);
var result = this.build();
return result;
};
Builder.addInterceptor.implementation = function (interceptor) {
this.interceptors().clear();
//var MyInterceptorObj = MyInterceptor.$new();
this.interceptors().add(MyInterceptorObj);
return this;
//return this.addInterceptor(interceptor);
};
console.log("hook_okhttp3...");
});
}
用spawn方式启动app
frida -U --no-pause -f xxx -l hook.js
