1． Python环境安装【目前使用版本为：python2.7.5】
2． 安装服务启动需要模块
yum install python-pip :如果无法直接通过下载安装，请移步至官方下载: https://pypi.python.org/pypi/pip/;下载时使用版本pip-8.1.0.tar.gz
如果下载本地环境的话，需要上传至服务器：
tar -zxvf pip-8.1.0.tar.gz cd pip-8.1.0 python setup.py install
安装成功如下图：
3. 安装依赖环境：
pip install flask
安装成功效果如下图：
注：如果出现上图中的黄色提示信息，请按提供进行pip版本的升级，执行命令：pip install --upgrade pip
pip install validictory
安装成功效果图：
pip install logging
安装成功效果图：
pip install langid
安装效果图：
4. 启动服务：nohup python Language_Detection.py &
服务具体代码如下：
# coding=utf8 ‘‘‘ Created on 2015年4月17日 @author: Jack 杰之蓝 ‘‘‘ import langid from flask import Flask, request, abort, Response import logging import json import validictory class Language_detection: def __init__(self,logger): self.logger = logger def post(self): if not request.json: abort(400) self.logger.info(‘Received new task [POST]‘) self.logger.info(request.json) result = self._dispatch_task(request.json) return self._wrap_result(result) def get(self): args = request.args.to_dict() self.logger.info(args) result = self._dispatch_task(args) self.logger.info(‘Received new task [GET]‘) return self._wrap_result(result) def _dispatch_task(self,task): result = {} try: self._validate(task) except ValueError as e: return {"errorCode":1, "errorMessage": str(e)} try: result[‘result‘] = langid.classify(task[‘text‘])[0] except ValueError as e: return {"errorCode":2, "errorMessage": str(e)} result[‘errorCode‘] = 0 result[‘errorMessage‘] = ‘Succeed‘ return result def _wrap_result(self,result): dump = json.dumps(result, encoding = ‘utf-8‘, ensure_ascii=False, indent=4) callback = request.args.get(‘jsoncallback‘) if callback: return ‘%s(%s)‘ % (callback, dump) else: return Response(json.dumps(result, encoding=‘utf-8‘, ensure_ascii=False, indent=4), mimetype=‘application/javascript‘) def _validate(self,task): schema = { ‘type‘: ‘object‘, ‘properties‘: { ‘text‘: {‘type‘: "string"} }, } validictory.validate(task,schema) def main(): app = Flask(__name__) logging.basicConfig(level=logging.DEBUG, format="%(asctime)s - %(name)s - %(message)s") logger = logging.getLogger(‘Language detection‘) detection = Language_detection(logger) app.route(‘/detection‘, methods = [‘POST‘])(detection.post) app.route(‘/detection‘)(detection.get) app.run(host = ‘‘, port = 9006, threaded = True) if __name__ == "__main__": main()
5. 服务调用：
http://172.16.4.200:9006/detection?text=你好,杰之蓝
调用结果：
{
"errorCode": 0,
"errorMessage": "Succeed",
"result": "zh"
}
