python 调用github的api,呈现python的受欢迎的程度

时间：2022-10-15 16:15:20

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'])

4仓库的信息

仓库的信息:

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:

python 调用github的api,呈现python的受欢迎的程度

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')

python 调用github的api,呈现python的受欢迎的程度

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
