python 调用github的api,呈现python的受欢迎的程度

发布时间：2020-12-20 12:47:13 所属栏目：Python 来源：网络整理
导读：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:pythonsort=starts ?这个api调用github当前托管的python项目 { " total_count " : 3872430 , " incomplete_results " : true, " items " : [ { " id "

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:

{
      "id": 21289110,"owner": {
        "login": "vinta","id": 652070,"node_id": "MDQ6VXNlcjY1MjA3MA==","avatar_url": "https://avatars2.githubusercontent.com/u/652070?v=4","gravatar_id": "","url": "https://api.github.com/users/vinta","html_url": "https://github.com/vinta","followers_url": "https://api.github.com/users/vinta/followers","following_url": "https://api.github.com/users/vinta/following{/other_user}","gists_url": "https://api.github.com/users/vinta/gists{/gist_id}","starred_url": "https://api.github.com/users/vinta/starred{/owner}{/repo}","subscriptions_url": "https://api.github.com/users/vinta/subscriptions","organizations_url": "https://api.github.com/users/vinta/orgs","repos_url": "https://api.github.com/users/vinta/repos","events_url": "https://api.github.com/users/vinta/events{/privacy}","received_events_url": "https://api.github.com/users/vinta/received_events","type": "User","site_admin": false

      },"forks": 13570,"open_issues": 464,"watchers": 69602,"default_branch": "master","score": 1.0
    },

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‘,‘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,"integration_manifest": {
      "limit": 5000,"remaining": 5000,"reset": 1562495790
    }
  },"rate": {
    "limit": 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,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
