Flask介紹

Flask是一個非常輕量級的Python Web框架。使用Flask可以很容易地部署演算法服務，通過HTTP方式對外提供API響應介面。
以敏感詞檢測演算法為例。 如果要部署其他演算法，程式碼對應做一些修改既可。

部署程式碼

from flask import Flask, request
from sensitive_word_detect import SensitiveWordDetect

app = Flask(__name__)

# 此處做一些檔案讀取、類例項化、計算圖載入等預處理的工作
sensitive_words_path = './word_files/senti_words.txt' # 敏感詞列表
stopWords_path = './word_files/stop_words.txt' # 特殊符號列表
detector = SensitiveWordDetect(sensitive_words_path, stopWords_path)

@app.route('/sentiwords', methods=("POST",))
def sentiwords():
    line = request.form['line']
    
    sensitive_words = ''
    if line.strip() != '':
        _, sensitive_lst = detector.replace_sensitive_word(line)
        for word in sensitive_lst:
            sensitive_words += word + ','
    
    if sensitive_words.strip() == '':
        rst = {
                "legal":"通過",
                "body":[]
        }
    else:
        rst_lst = []
        if sensitive_words.strip() != '':
            rst_lst.append({
                       "type":"包含敏感詞",
                       "content":sensitive_words
                    })
        rst = {
            "legal":"不通過",
            "body":rst_lst
        }
    return rst

if __name__ == '__main__':
    app.config['JSON_AS_ASCII'] = False
    app.run(host='0.0.0.0', port=8000)
 

呼叫測試

# coding=UTF-8
from datetime import datetime
import requests

starttime = datetime.now()

text_path = "./test_files/000.txt"  # 文字路徑

content = [] # 臨時儲存文字
with open(text_path, 'r', encoding='utf-8') as f:
    content = f.readlines()

line = ''.join(content)
data = {"line": line}
headers = {
    'Connection': 'close',
    }
r = requests.post('http://0.0.0.0:8000/sentiwords', data=data, headers=headers)

if str(r.status_code) != '200':
    print("status_code: ", str(r.status_code))
    print(r.text)
    
elif r.json()['legal'] == '不通過':
    for temp in r.json()['body']:
        if temp['type'] == '包含敏感詞':
            sensitive_word_result = temp['content']
    print(sensitive_word_result)
        
endtime = datetime.now()
time_consume = endtime - starttime
print('敏感詞檢測完成，共用時{}'.format(time_consume))
