A little friend came to me to develop a system. This time he wanted to test my efficiency. He met this condition for the first time.

2000 for one week, 4000 for three days and 5000 for one day.

That's what I said. What am I dragging on?

After the completion of the system, we discussed with him and refunded part of his cost. The source code was open to everyone. Convenient little partner, forward, with the support of watching. Your support is the driving force for me to move forward. If it's inconvenient, it's OK. Hey hey

First of all, his needs are not very difficult. After combing them, I feel there is no problem and start working directly.

Let's wait and see if that day can be completed?

1, Technical selection:

2, Prototype design:

The other party has no UI requirements and the budget is low. This step is ignored directly. I developed the UI application earlier. Picture processing ps get the icon picture or something

3, Software download and installation, environment installation:

The software download addresses and installation tutorials are arranged in great detail. Whenever I change a computer, I directly download and install the following, which is really finished quickly, as shown below:

The download of the system can also be provided to you.

4, System demonstration:

If you want to see the complete video demonstration, it is as follows:

6, System source code acquisition

Still that sentence, only limit learning and use!

If I find a thief, I will open source less in the future! And will hold you accountable!

Finally, I hope you can give me a third company! Open source is not easy!

If you also want to learn this system, it has been open source. Please get it below. Reply: Pets
