python 调用github的api,呈现python的受欢迎的程度

概述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": 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 requestsurl = ‘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keysprint(response_dict.keys())# dict_keys([‘total_count‘,‘incomplete_results‘,‘items‘])

 

 4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: PyCharmimport requestsurl = ‘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 requestsimport pygalfrom pygal.style import lightcolorizedStyle as LCS,lightenStyle as LSurl = ‘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 = nameschart.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: PyCharmimport requestsimport pygalfrom pygal.style import lightcolorizedStyle as LCS,base_style=LCS)my_config = pygal.Config()my_config.x_label_rotation = 45my_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 = 24my_config.label_Font_size  = 14my_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 = nameschart.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
