1. 產業板塊
產業類股與概念股在定義上還是有很大的差別。
一般來說，概念板塊的風險更大，基於某個消息被短期炒作，很不穩定，因此風險更大
行業板塊是按股票行業進行分類，往往注重於長期，穩定性更高。
在實際投資上，短期可以根據「 市場熱點 」從概念股進行選股投資，中長期還是建議按「 產業板塊 」選股投資。
2. 爬取相關板塊及個股列表
目標對象：
aHR0cDovL3N1bW1hcnkuanJqLmNvbS5jbi9oeWJrLw==
2-1 板塊清單
首先，我們使用「 Toggle JavaScript」外掛程式發現頁面中的產業板塊資料來自下面的請求結果
https://www.php.cn/link/6e839dd93911f945cd02c9b15da23db0
#其中，參數為p 和_dc 為可變參數，p 代表頁碼數（從1 開始），_dc 代表13 位元的時間戳，其他查詢參數都是固定內容
然後，我們編寫程式碼取得回應數據，使用正規表示式匹配出行業列表的數據
...
self.ps_url = 'http://**/?q=cn|bk|17&n=hqa&c=l&o=pl,d&p={}050&_dc={}'
....
def __get_timestramp(self):
"""
获取13位的时间戳
:return:
"""
return int(round(time.time() * 1000))
...
def get_plates_list(self, plate_keyword):
"""
获取所有板块
:return:
"""
plates = []
index = 0
while True:
url = self.ps_url.format(index + 1, self.__get_timestramp())
# 解析数据
resp = self.session.get(url, headers=self.headers).text
match = re.compile(r'HqData:(.*?)};', re.S)
result = json.loads(re.findall(match, resp)[0].strip().replace("n", ""))
if not result:
break
# 根据关键字，过滤有效板块
temp_plate_list = [item for item in result if plate_keyword in item[2]]
index += 1
for item in temp_plate_list:
print(item)
plates.append({
"name": item[2],
"plate_path": item[1],
"up_or_down": str(item[10]) + "%",
"top_stock": item[-6]
})
return plates
...
最後，根據關鍵字對板塊進行一次篩選，通過板塊名、板塊路徑PATH、板塊漲跌幅、最大貢獻股票名稱重新組裝成一個清單
注意：透過分析頁面發現，根據板塊路徑PATH 可以組裝成產業板塊個股清單頁面URL
##例如，產業板塊PATH 為400128925，那麼產業板塊對應個股清單的頁面URL 為
https://www.php.cn/link /0cb5ebb1b34ec343dfe135db691e4a85
2-2 產業個股列表爬取產業個股列表和上一步資料展示邏輯一樣，個股列表資料資料同樣來源於下面請求的結果
https://www.php.cn/link/f9995e4c8a1e54123c64427a572d7917
#其中，bk 後面對應產業板塊PATH，p 代表頁碼數，_dc 代表13 位元的時間戳記...
# 个股
self.stock_url = 'https://www.php.cn/link/f9995e4c8a1e54123c64427a572d7917'
....
def get_stock_list(self, plate_path):
"""
获取某一个板块下所有的个股信息
包含：股票名称、最新价格、涨跌幅、市盈率
:param plate_info:
:return:
"""
index = 0
stocks = []
while True:
url = self.stock_url.format(plate_path, index + 1, self.__get_timestramp())
resp = self.session.get(url, headers=self.headers).text
match = re.compile(r'HqData:(.*?)};', re.S)
result = json.loads(re.findall(match, resp)[0].strip().replace("n", ""))
if not result:
break
index += 1
for item in result:
if item[-1] < 0:
continue
stocks.append({
"stock_name": item[2],
"pe": item[-1],
"price": item[8],
"up_or_down": str(item[12]) + "%"
})
# 按pe降序排列
stocks.sort(key=lambda x: x["pe"])
return stocks
透過正規表示式對回應結果進行配對後，取得個股的名稱、PE 本益比、價格、漲跌幅4 個關鍵資料最後，將個股清單按PE 進行升序排列後直接回傳3.服務化當然，我們可以將這部分邏輯服務化供前端使用，以此提升使用者的體驗性例如，使用FastAPI 可以快速建立兩個服務：根據關鍵字取得產業板塊清單、根據板塊路徑取得個股清單

Uniapp 為例，使用uni-table 元件展示產業板塊清單及個股清單
部分程式碼如下：//个股列表 platestock.vue
...
<view >
<uni-forms ref="baseForm" :modelValue="baseFormData" :rules="rules">
<uni-forms-item label="关键字" required name="content">
<uni-easyinput v-model="baseFormData.content" placeholder="板块关键字" />
</uni-forms-item>
</uni-forms>
<button type="primary" @click="submit('baseForm')">提交</button>
<!-- 结果区域 -->
<view v-show="result.length>0">
<uni-table ref="table" border stripe emptyText="暂无数据">
<uni-tr >
<uni-th align="center" width="100%">板块</uni-th>
<uni-th align="center" width="100%">涨跌幅</uni-th>
<uni-th align="center" width="100%">强势股</uni-th>
</uni-tr>
<uni-tr v-for="(item, index) in result" :key="index" @row-click="rowclick(item)">
<uni-td align="center">{{ item.name }}</uni-td>
<uni-td align="center" >{{ item.up_or_down }}</uni-td>
<uni-td align="center" >{{ item.top_stock }}</uni-td>
</uni-tr>
</uni-table>
</view>
</view>
...
methods: {
//表单提交数据
submit(ref) {
this.$refs[ref].validate().then(res => {
this.$http('xag/plate_list', this.baseFormData, {
hideLoading: false,
hideMsg: false,
method: 'POST'
}).then(res => {
console.log("内容：", res.data)
if (res.data && res.data.length > 0) {
this.$tip.success("查询成功！")
this.result = res.data
} else {
this.$tip.success("查询结果为空,请换一个关键字查询！")
}
}).catch(err => {
console.log("产生异常，异常信息：", err)
})
}).catch(err => {
console.log('err', err);
})
}
...
最後部署完專案後，在前端頁面就能根據板塊名稱選擇合適的個股進行投資了
4. 總結一下
由於產業板塊更適用於中長期投資，我們只需要根據某一個關鍵字篩選出一個板塊，然後在板塊下的個股列表中可以非常直觀地看出市盈率較低的個股進行投資即可。以上是教你用 Python 快速取得產業板塊股，輔助價值投資！的詳細內容。更多資訊請關注PHP中文網其他相關文章！
