All the source code has been packaged and uploaded to Github.

A preface.

In September 2019, I came to Taizhou Vocational And Technical College and started my code study.

I will leave Taizhou Vocational And Technical College in July 2021. There are still half a month left. From then on, I will leave the campus and become a professional.

Wake up in the morning, the teacher in charge in the group of notice according to graduation, the day after tomorrow is also less than two years of time, how fast you may wonder why, yes, I am a junior college student, was a sophomore, title at the beginning of “graduation design”, it could have been my fantasy’s graduation design, the school has never been what kind of graduation design, but the corresponding period of one year of field work, At the end of June, I will go to Nanjing for my internship.

The school does not need a graduation project, but I think I should still make something out, to tell myself that these two years, not to lie down, but also can write on the resume of the project.

School fair is organized in May, first of related, is held in our college, said to be related, but I can’t see where there are related, what customer service, sheet metal working, test, most probably the most intensely is a operations, a company brochure with development engineer, I will throw a resume, also can also chat, Had asked for an interview as a result, can also tell me ability, is the technology does not build, and they push to take off me, I also learned in students, after a lot of classmates even couldn’t get in your resume, just said don’t hire college development, it makes me feel full of malice, then followed by a whole school job fairs, said there are hundreds of companies, But it has nothing to do with programming.

At least at last through a recruitment operation and maintenance personnel recommendation, attended the development interview, successfully passed the C++ development engineer internship.

I wrote a summary before: the 2020 annual summary [some people still don’t believe it, that means I’m ok. Haha], wrote about the awards I won, participated in, and served as a student leader.

No matter how brilliant you in school, but in fact these during the interview and not play any role, on a resume don’t long what activities do you participate in or organize the, what took part in the student union, especially our programmers, the interviewer will feel you will take part in the activity, don’t knock on the code, so they only need to be in a good, awards, Just write down a few of the things you’re most proud of. The biggest benefits of any awards you’ve won in school are probably the scholarships you earned (I got through the semester with them).

If you have projects on your resume, chances are the interviewer will ask you questions about them, so project experience is your core competence. Take care of your projects and upload code to Github.

Then graduation season also have nothing to say, still focus on my “gadgets”, about 4000 lines of code, actually say much more, but also pretty much, in a blog is uploaded to making all this treasure, this gadget is the most careful I until now a small project, I do not hesitate to buy a year cloud server, I plan to continue to refine the code and add functionality over time.

Want to give you some advice here, everybody wants to take their thinking to write code, not all has been written, if you ask people how to learn programming, the somebody else will say much knock code, much knock here to bring your own thinking, can think of this code can be optimized, can function is subdivided, modular, How to design can make later add function as far as possible not to modify the previous code, if not with thinking, is always a running account of a kind of writing, can never progress.

2. Imitate QQ communication

The Fdog im project source code has been packaged and uploaded to github.com/HuaGouFdog/… If you don’t understand, please remember to chat with me privately. If it is helpful to you, welcome to Star!

1. Introduction

Basic six:

Fdog series (1) : thinking, it is better to write a chat software, then from the imitation QQ registration page to start. Fdog series (2) : how to write HTML after the registration page, write the background response in Java. Fdog series (iii) : Use Tencent Cloud SMS interface to send SMS, write to the database, deploy to the server, web ending. Fdog series (four) : the use of Qt framework imitation QQ login interface, interface. Fdog series (5) : Use Qt to imitate QQ login interface to the main interface, function article Fdog series (6) : Qt to achieve client and client through the server to communicate with each other

Fdog instant messaging, is I at the beginning of April, by now almost have more than two months, and had written six basic article, article 6 of the time on May 4, I remember correctly, 7, and then open the job fair, after time has also been busy looking for a job, I got to pick it up again in June, so delayed. In particular, the sixth article: Qt client and client through the server to communicate with each other, can find little information on the Internet, there are want to achieve similar functions of small partners can see.

Use the knowledge learned in school to write, mainly including web, client, and server.

  1. The web side mainly uses HTML front end and Java back end, and uses Tomcat to deploy on Tencent cloud server, and functions such as internship software download and account registration.
  2. Client and server is in the Window platform using QT5.10 for writing, practice to add friends, friends chat and other functions.

Remark:

Related software versions: Tomcat7.x, mysql7.x, Centos7.x

The SMS uses Tencent Cloud’s SMS service. Other SMS services require enterprise authentication, but Tencent Cloud does not.

Every new user who registers Tencent Cloud has two months of SMS experience. My experience has expired and I cannot send SMS normally now. Do not try to register again.

Because the server database password and other important information can not be uploaded, so downloaded down the program can not run normally, here only provide source code and related database fields.

Currently github does not upload executable files (too large and github is slow). If the source code fails to compile after downloading, right-click the project and rebuild it.

Fdog website: www.fdogcsdn.cn. The corresponding executable file on PC can be obtained by adding me. There is an official QR code on the left side of the home page.

It’s been a month since some fans asked me about it. I’m not updating the sixth post. Don’t worry, it’s growing all the time.
