Group Buying client exercises (1: Think about it) and Group Buying client exercises and thoughts
Group Buying app project exercises

This is because it is good for future work.

After reading the APIS provided by several group buying websites, it's okay to contact the third-party group buying navigation websites.

There are few poor things in the api, And the api is an xml file. There are developer documents and other instructions. Some things can only be guessed to know what it is.

A city list and a commodity details are like this.

　　

Start with the xml file.

About 30 M in a city. A rough line. Look at other demos. Some people have loaded all the parsing and the website speed limit is about 1024/160 K. The calculation is about 30 M * 192 K = s. 3 minutes

I opened an app and waited for three minutes to see the data. Even the demo exercise brother could not bear it.

Then, you can only regularly update the parsing results on your own every day, open a server, put the data on it, and then fetch it.

This is initially the case.

　　

Now, it's quite convenient to have a free app background without spending money on cloud hosts. However, after all, just a few cloud functions can only use JavaScript

Hahaha start re-entering js tomorrow

There is nothing wrong with the data. I'm excited here to cry.

Analyze the xml file and confirm the data and name.

Mathematical questions (Exercise 13 questions in the first grade)

The numbers 21, 22, 23, 24, 25, 26, 27, 28, and 29 are arranged in three rows, three in each row, add the numbers of the horizontal, vertical, and oblique rows to 75.




Think about this problem

Pursuing "foreign style" and "fashion" in terms of clothing, food, housing, and travel --- this is vanity.

Traveling to Yunnan, Tibet, Guizhou, and other remote areas shows great interest in the living environment and lifestyle of local ethnic minorities-this is by nature
