python 调用github的api,呈现python的受欢迎的程度
1 使用api调用数据:
在浏览器的地址栏中输入:
https://api.github.com/search/repositories?q=language:python&sort=starts
这个api调用github当前托管的python项目
{
"total_count": 3872430,
"incomplete_results": true,
"items": [
{
"id": 21289110,
"node_id": "MDEwOlJlcG9zaXRvcnkyMTI4OTExMA==",
"name": "awesome-python",
"full_name": "vinta/awesome-python",
"private": false,
---snip----
"total_count": github上共有的python项目
"incomplete_results": true, 表示请求成功,如果github无法处理该api他返回的值是true
"items"python项目的具体的信息
2 安装requests,
requests 可以让python程序轻松向网站请求信息以及检查返回的响应
pip install --user requests
代表仅该用户的安装，安装后仅该用户可用。处于安全考虑，尽量使用该命令进行安装。
3 简单的处理api的响应
import requests
url = 'https://api.github.com/search/repositories?q=language:python&sort=starts'
r = requests.get(url) # 打印出状态码
print('status code',r.status_code)
# status code 200 转态码 200表示成功 response_dict = r.json() # 打印出所有的keys
print(response_dict.keys())
# dict_keys(['total_count', 'incomplete_results', 'items'])

简单的仓库的信息做介绍:具体的介绍看文档
响应的api已经按照stargazers_count进行排序了,第一个仓库就是星最高的
name 项目的名称
owner项目的拥有者的信息
stargazers_count 项目获取的星的个数
repos_url 项目的url
created_at 项目创建的时间
updated_at 项目更新的时间
5 打印仓库的信息(项目名称,项目的拥有者,项目的星数,项目的描述)
#!/usr/bin/env python
# -*- coding:utf-8 -*-
# @Author : linlin
# @Software: PyCharm import requests
url = 'https://api.github.com/search/repositories?q=language:python&sort=starts'
r = requests.get(url) # 打印出状态码
print('status code',r.status_code)
# status code 200 转态码 200表示成功 response_dict = r.json() # 打印出所有的keys
print(response_dict.keys())
# dict_keys(['total_count', 'incomplete_results', 'items']) #共有多少个python的项目
print(response_dict['total_count']) # 有关仓库的信息
repo_dicts = response_dict['items']
print('Repositors returned',len(repo_dicts)) for repo_dict in repo_dicts:
# 项目的名称
print(repo_dict['name'])
# 项目的拥有者
print(repo_dict['owner']['login'])
# 项目的星数
print(repo_dict['stargazers_count'])
# 项目的url
print(repo_dict['html_url'])
# 项目的描述
print(repo_dict['description'])
6 监视api的速率限制
大多数的api都存在api速率限制,在特定的时间内可以执行的请求数存在限制,,看github的限制,请在浏览器上输入https://api.github.com/rate_limit
{
"resources": {
"core": {
"limit": 60,
"remaining": 60,
"reset": 1562495790
},
"search": {
"limit": 10,
"remaining": 10,
"reset": 1562492250
},
"graphql": {
"limit": 0,
"remaining": 0,
"reset": 1562495790
},
"integration_manifest": {
"limit": 5000,
"remaining": 5000,
"reset": 1562495790
}
},
"rate": {
"limit": 60,
"remaining": 60,
"reset": 1562495790
}
}
search 的解释:
"search": { "limit": 10, 每分钟10个请求
"remaining": 10, 在当前一分钟还可以请求10次
"reset": 1562492250 }, 配额将重置unix时间或新世纪时间(1970年1月1日午夜多少秒),当配额用完,您将收到一条简单的响应,有此可知,已达到api的极限,到达极限等待配额重置
配额用完访问https://api.github.com/search/repositories?q=language:python&sort=starts status code 403状态码是403
7 使用pygal可视化仓库
使用图形将项目的受欢迎的程度表示出来
import requests
import pygal
from pygal.style import LightColorizedStyle as LCS, LightenStyle as LS url = 'https://api.github.com/search/repositories?q=language:python&sort=starts'
r = requests.get(url) # 打印出状态码
print('status code',r.status_code)
# status code 200 转态码 200表示成功 response_dict = r.json() # 有关仓库的信息
repo_dicts = response_dict['items'] names,starts = [],[]
for repo_dict in repo_dicts:
names.append(repo_dict['name'])
starts.append(repo_dict['stargazers_count']) # 可视化 # 定义图形的格式 333366 蓝色的
my_style = LS('#333366',base_style=LCS)
# x_lable_rotation 标签倾斜45度 show_legend=False 隐藏图例
chart = pygal.Bar(style=my_style,x_lable_rotation=45,show_legend=False) # 图标的标题
chart.title= 'Most-Stsrred Python Projects on Github'
chart.x_labels = names
chart.add('',starts)
chart.render_to_file('python_repos.svg')
运行项目会生成python_repos.svg 文件用浏览器打开:
8 改进pygal图标
#!/usr/bin/env python
# -*- coding:utf-8 -*-
# @Author : linlin
# @Software: PyCharm import requests
import pygal
from pygal.style import LightColorizedStyle as LCS, LightenStyle as LS url = 'https://api.github.com/search/repositories?q=language:python&sort=starts'
r = requests.get(url) # 打印出状态码
print('status code',r.status_code)
# status code 200 转态码 200表示成功 response_dict = r.json() # 有关仓库的信息
repo_dicts = response_dict['items'] names,starts = [],[]
for repo_dict in repo_dicts:
names.append(repo_dict['name'])
starts.append(repo_dict['stargazers_count']) # 可视化 # 定义图形的格式 333366 蓝色的
my_style = LS('#333366',base_style=LCS) my_config = pygal.Config()
my_config.x_label_rotation = 45
my_config.show_legend = False # 图标标题,副标题.,主标签的字体的大小
my_config.title_font_size = 24
my_config.label_font_size = 14
my_config.major_lable_font_size = 18 # 较长的项目名缩短为15个字符,鼠标移动到被截断的项目名,会显示完整的项目名
my_config.truncate_label = 15
# 隐藏图标的水平线
my_config.show_y_guides = False
# 自动定义高度
my_config.width = 1000 # x_lable_rotation 标签倾斜45度 show_legend=False 隐藏图例
chart = pygal.Bar(my_config,style=my_style) # 图标的标题
chart.title= 'Most-Stsrred Python Projects on Github'
chart.x_labels = names
chart.add('',starts)
chart.render_to_file('python_repos.svg')
9 添加自定义工具提示
在pygal中,将鼠标指向条形将显示它表示的信息,这通常称为工具提示,创建工具栏,同时显示项目的描述,获取的星
