The eighth day

Since Xiao Shuai Shuai walked into the misty forest of Taobao Open Platform, he felt that the misty forest was so big, just when he was at a loss.

A pleasant voice sounded, and the sweet voice said: Dear, do you want to pass through this forest? I will guide you forward.

When Xiao Shuaishuai heard that feeling, his body involuntarily followed the sound, and suddenly a bright light flashed, ah...

Xiao Shuai Shuai woke up with a start. When Xiao Shuai Shuai looked at the time, I was surprised that it was so late. In this way, Xiao Shuai Shuai was late for the first time in his career.

Actually, Xiao Shuai Shuai spent a whole night thinking about it on the platform, but he didn’t really figure out anything during the whole night.

Just when I was about to arrive at the company, my cell phone rang. I saw it was Boss Yu and answered the call.

Boss Yu greets me: Good morning, Xiao Shuai Shuai. When will you arrive at the company?

Xiao Shuai Shuai replied: Boss Yu, I’m sorry, I was too busy studying the Taobao open platform last night and overslept this morning. But I’m almost at the company....

When Boss Yu heard this, he was embarrassed to blame Xiaoshuai, so he had to say: Thank you for your hard work, pay attention to rest, and learn to combine work and rest...

Xiao Shuai Shuai, back to: Okay, thank you Boss Yu for your teaching, I’ll just hang up if it’s okay. . (0Afraid of the boss’ sugar-coated bullets0)

After Xiao Shuai Shuai returned to the company, Boss Yu gave Xiao Shuai Shuai a compiled Topclient and asked him to study it. It seemed that Xiao Shuai Shuai was still willing to study the code and let him see the open platform. I really can't see anything.

Taobao API documentation: http://open.taobao.com/api/api_cat_detail.htm?spm=a219a.7386789.0.0.AjaroV&cat_id=4&category_id=102
