1-讯飞星火

进入讯飞官网进行创建应用，获取相关密钥APPID，APISecret，APIKey，选择最新版本
首次调用讯飞官方api可能有两问题：

1-No module named 'websocket'#安装 pip install websocket_client==1.4.2
2-spark_url="ws(s)://spark-api.xf-yun.com/v3.1/chat" #改为"ws://spark-api.xf-yun.com/v3.1/chat"

现搞了个完整的代码如下：
第一个相关请求的代码：SparkApi.py 相关参数可自行修改

1_3-调用api

prompt的基本写法规则：
任务：明确而简洁地陈述Prompt 要求模型生成的内容
指令：模型在生成文本时应遵循的指令。
角色：模型在生成文本时应扮演的角色。

prompt1="""将文本分类为中性、负面或正面。文本：我认为这次假期还可以。情感："""
from Chat_spark import SparkProcessor
result = SparkProcessor.spark_api(prompt1)
print(result)#中性

3-两者之间比较与openai

目前国内的效果在某些方面还是差点意思，没有公开过prompt实例，文心对格式控制很难把控，很难去掉提示语，星火给出的结果有时候偏差很大，估计还得明年中旬，训练慢慢好起来。
