PlayFramework completely implements an APP (4)
app
The last error in the previous article was due to an error in the assertion assertEquals(1, Post.count()); and the number of Posts obtained was not 1. Before running the Test, there was data in the table
You can add the following method to run the Test Clear data before
@Before
public void setup() {
Fixtures.deleteAll();
}
1. Write complex test cases
Edit/test/data.yml
# User(bob ):
# email: bob@Gmail.com
# passWord: secret
# fullname: Bob
Replace the content with http://play-framework.herokuapp.com/zh/files/data.yml
Add test cases
@Test
public void fullTest() {
Fixtures.loadModels("data.yml");
// Count things
assertEquals(2, User.count());
assertEquals(3, Post .count());
assertEquals(3, Comment.count());
// Try to connect as users
assertNotNull(User.connect("bob@gmail.com", "secret"));
assertNotNull (User.connect("jeff@gmail.com", "secret"));
assertNull(User.connect("jeff@gmail.com", "badpassword"));
assertNull(User.connect("tom@ gmail.com", "secret"));
// Find all of Bob's posts
List
.fetch() ;
assertEquals(2, bobPosts.size());
// Find all comments related to Bob's posts
List
"bob@gmail.com ").fetch();
assertEquals(3, bobComments.size());
// Find the most recent post
Post frontPost = Post.find("order by postedAt desc").first();
assertNotNull (frontPost);
assertEquals("About the model layer", frontPost.title);
// Check that this post has two comments
assertEquals(2, frontPost.comments.size());
// Post a new comment
frontPost.addComment("Jim", "Hello guys");
assertEquals(3, frontPost.comments.size());
assertEquals(4, Comment.count());
}
Regarding how to use data.yml, you can refer to http://play-framework.herokuapp.com/zh/yaml
2. Initialize data
Start creating the first page of the application. This page will display recent posts, as well as a list of older articles.
We need one thing before developing the first screen. Create test data. One way to inject default data into your blog is to load the file at application load time. To do this, we will create a bootstrap job.
Create Bootstrap.java
package models;
import play.*;
import play.jobs.*;
import play.test.*;
@OnapplicationStart
public class Bootstrap extends Job {
public void doJob( ) {
// Check if the database is empty
if (User.count() == 0) {
Fixtures.loadModels("initial-data.yml");
}
}
}
initial-data .yml uses the content of data.yml to create the default data
@OnApplicationStart identification method to run when the application starts
3. Develop the homepage
Modify the index() method of Application.java
public static void index () {
Post frontPost = Post.find("order by postedAt desc").first();
List
.fetch( 10);
render(frontPost, olderPosts);
}
Modify Application/index.html
#{extends 'main.html' /}
#{set title:'Home' /}
#{if frontPost}
#{if olderPosts.size()>1}
#{/if}
#{/if}
#{else}
There is currently nothing to read here.
#{/else }

How to decrypt app resources in cocos2d-LUA reverse engineering
May 16, 2023 pm 07:11 PM
Let's take the Dashen apk as an example. Through the previous analysis of the app decryption Lua script, we can decrypt the Lua script of the Dashen apk. Now let's decrypt its resources (configuration files and pictures, etc.). Let’s take a more important configuration file as an example. Before decryption: the file header also has a signature value: fuckyou!. Seeing this, we first thought about whether it was also encrypted with xxtea. We used the above method to decrypt it with xxtea first, and then decompressed it. We found that it was still garbled, and an error occurred during the operation. Obviously, we have to deny what we just said. conjecture. We continue to decrypt the configuration file step by step. Think about it for a moment, the file header is: fuckyou!

Using this vulnerability, the Facebook Android APP installed on the user's mobile phone can be converted into a backdoor program (Backdoor) to achieve backdooring.
