使用Flask构建一个简单的服务端
该服务端能够接收POST请求，并返回词频统计结果
先运行该代码搭建起服务端，然后运行request文件进行词频统计
app = Flask(__name__)
@app.route('/word_frequency', methods=['POST'])
def word_frequency():
# 获取POST请求中的JSON数据
data = request.get_json()
data = data['file']
# 统计词频
word_freq = get_frequencies(data)
word_freq = sort_dict(word_freq)
return word_freq
if __name__ == '__main__':
app.run(debug=True)
