實現(xiàn)思路
1.打開騰訊招聘的網(wǎng)址右擊檢查進行抓包，進入網(wǎng)址的時候發(fā)現(xiàn)有異步渲染，我們要的數(shù)據(jù)為異步加載
2.構(gòu)造起始地址：
start_url = ‘https://careers.tencent.com/tencentcareer/api/post/Query’
參數(shù)在headers的最下面
timestamp: 1625641250509
countryId:
cityId:
bgIds:
productId:
categoryId:
parentCategoryId:
attrId:
keyword:
pageIndex: 1
pageSize: 10
language: zh-cn
area: cn
3.發(fā)送請求，獲取響應(yīng)
self.start_url = 'https://careers.tencent.com/tencentcareer/api/post/Query'
# 構(gòu)造請求參數(shù)
params = {
# 捕捉當前時間戳
'timestamp': str(int(time.time() * 1000)),
'countryId': '',
'cityId': '',
'bgIds': '',
'productId': '',
'categoryId': '',
'parentCategoryId': '',
'attrId': '',
'keyword': '',
'pageIndex': str(self.start_page),
'pageSize': '10',
'language': 'zh-cn',
'area': 'cn'
}
headers = {
'user-agent': random.choice(USER_AGENT_LIST)
}
response = session.get(url=self.start_url, headers=headers, params=params).json()
4.提取數(shù)據(jù)，獲取崗位信息大列表，提取相應(yīng)的數(shù)據(jù)
# 獲取崗位信息大列表 json_data = response['Data']['Posts'] # 判斷結(jié)果是否有數(shù)據(jù) if json_data is None: # 沒有數(shù)據(jù)，設(shè)置循環(huán)條件為False self.is_running = False # 反之，開始提取數(shù)據(jù) else: # 循環(huán)遍歷，取出列表中的每一個崗位字典 # 通過key取value值的方法進行采集數(shù)據(jù) for data in json_data: # 工作地點 LocationName = data['LocationName'] # 往地址大列表中添加數(shù)據(jù) self.addr_list.append(LocationName) # 工作屬性 CategoryName = data['CategoryName'] # 往工作屬性大列表中添加數(shù)據(jù) self.category_list.append(CategoryName) # 崗位名稱 RecruitPostName = data['RecruitPostName'] # 崗位職責 Responsibility = data['Responsibility'] # 發(fā)布時間 LastUpdateTime = data['LastUpdateTime'] # 崗位地址 PostURL = data['PostURL']
5.數(shù)據(jù)生成折線圖、餅圖、散點圖、柱狀圖
# 第一張圖：根據(jù)崗位地址和崗位屬性二者數(shù)量生成折線圖
# 146，147兩行代碼解決圖中中文顯示問題
plt.rcParams['font.sans-serif'] = ['SimHei']
plt.rcParams['axes.unicode_minus'] = False
# 由于二者數(shù)據(jù)數(shù)量不統(tǒng)一，在此進行切片操作
x_axis_data = [i for i in addr_dict.values()][:5]
y_axis_data = [i for i in cate_dict.values()][:5]
# print(x_axis_data, y_axis_data)
# plot中參數(shù)的含義分別是橫軸值，縱軸值，線的形狀，顏色，透明度,線的寬度和標簽
plt.plot(y_axis_data, x_axis_data, 'ro-', color='#4169E1', alpha=0.8, linewidth=1, label='數(shù)量')
# 顯示標簽，如果不加這句，即使在plot中加了label='一些數(shù)字'的參數(shù)，最終還是不會顯示標簽
plt.legend(loc="upper right")
plt.xlabel('地點數(shù)量')
plt.ylabel('工作屬性數(shù)量')
plt.savefig('根據(jù)崗位地址和崗位屬性二者數(shù)量生成折線圖.png')
plt.show()
# 第二張圖：根據(jù)崗位地址數(shù)量生成餅圖 """工作地址餅圖""" addr_dict_key = [k for k in addr_dict.keys()] addr_dict_value = [v for v in addr_dict.values()] plt.rcParams['font.sans-serif'] = ['Microsoft YaHei'] plt.rcParams['axes.unicode_minus'] = False plt.pie(addr_dict_value, labels=addr_dict_key, autopct='%1.1f%%') plt.title(f'崗位地址和崗位屬性百分比分布') plt.savefig(f'崗位地址和崗位屬性百分比分布-餅圖') plt.show()
# 第三張圖：根據(jù)崗位地址和崗位屬性二者數(shù)量生成散點圖
# 這兩行代碼解決 plt 中文顯示的問題
plt.rcParams['font.sans-serif'] = ['SimHei']
plt.rcParams['axes.unicode_minus'] = False
# 輸入崗位地址和崗位屬性數(shù)據(jù)
production = [i for i in data.keys()]
tem = [i for i in data.values()]
colors = np.random.rand(len(tem)) # 顏色數(shù)組
plt.scatter(tem, production, s=200, c=colors) # 畫散點圖，大小為 200
plt.xlabel('數(shù)量') # 橫坐標軸標題
plt.ylabel('名稱') # 縱坐標軸標題
plt.savefig(f'崗位地址和崗位屬性散點圖')
plt.show()
# 第四張圖：根據(jù)崗位地址和崗位屬性二者數(shù)量生成柱狀圖

plt.rcParams['font.sans-serif'] = ['SimHei']

zhfont1 = matplotlib.font_manager.FontProperties(fname='C:\Windows\Fonts\simsun.ttc')
name_list = [name for name in data.keys()]
num_list = [value for value in data.values()]
width = 0.5 # 柱子的寬度
index = np.arange(len(name_list))
plt.bar(index, num_list, width, color='steelblue', tick_label=name_list, label='崗位數(shù)量')
plt.legend(['分解能耗', '真實能耗'], prop=zhfont1, labelspacing=1)
for a, b in zip(index, num_list): # 柱子上的數(shù)字顯示
plt.text(a, b, '%.2f' % b, ha='center', va='bottom', fontsize=7)
plt.xticks(rotation=270)
plt.title('崗位數(shù)量和崗位屬性數(shù)量柱狀圖')
plt.ylabel('次')
plt.legend()
plt.savefig(f'崗位數(shù)量和崗位屬性數(shù)量柱狀圖-柱狀圖', bbox_inches='tight')
