Python搜集Github中项目作者信息

我们将继续学习可视化部分的内容，我们将请求网站信息，并对这些信息进行可视化操作
很多API都要求注册获得API秘钥后才能执行API调用，但是Github没有这样的要求 https://api/github.com/将请求发送到GitHub网站中相应API调用的部分,search/repositories让API搜索 Github上的所有仓库 后面是传递的一个实参 q表示查询，通过language:python指出只想获取主要语言为Python的仓库信息
&sort=stars 指定将项目按其获得的星级进行排序

下面是代码部分:import requests
import sys

url = 'https://api.github.com/search/repositories?q=language:python&sort=starts'

r = requests.get(url)
print("Status Code: ", r.status_code)

# 将API响应存储到一个变量中
response_dict = r.json()

#print(response_dict.keys())
print("Toal repositories:", response_dict['total_count'])

# 查找有关仓库的信息
repo_dicts = response_dict['items']
print("Repositories returned:", len(repo_dicts))

# 打印出所有仓库的项目的一些信息
print("\nSelected information about first repository:")

def getRepositoryInfomation():

# 作者名
print('\nName:', repo_dict['name'])
# 登录名
print('Owner:', repo_dict['owner']['login'])
# 星星个数
print('Stars:', repo_dict['stargazers_count'])
# 仓库的url
print('Repository:', repo_dict['html_url'])
# 创建时间
print('Created:', repo_dict['created_at'])
# 更新时间
print('Updated:', repo_dict['updated_at'])
# 可能会出现这种情况,"description": null这样会返回一个NoneType异常
if type(repo_dict['description']):
print('Description: ', 'null')
else:

# 项目描述
print('Description:', repo_dict['description'])

for repo_dict in repo_dicts:
getRepositoryInfomation()

下一节我们将使用Pygal可视化这些数据
