天呢，太厉害了，作为一个前端学生，开发出来了一个AI程序！！！！
千帆大模型平台的控制台界面还是挺友好的，直接把开发流程给列出来了。
因为是调用API,所以按照常理，需要创建一个应用：
可以看到，可以调用N个模型的接口，嘿嘿，我还是选择了百度自研的ERNIE-Bot-turbo:
在左侧菜单导航中，找到应用接入菜单，并进入
然后创建
创建的很快，眨眼间就创建成功了：
点进去详情界面，就可以看到该应用的详细信息，API Key,Secret Key都是一会要用到的，可以先记录下来。
调用API
官方文档提供了基础写法
在Python3中可以使用requests可以比较友好的操作api请求：
#!/usr/bin/python3import requestsimport json# 一、获取access_tokenurl = "https://aip.baidubce.com/oauth/2.0/token"APIKey = "lWoUs2oSxE5WK8OVzfaNx5vg"SecretKey = "SRpXtKFx7QgatWoGraXc3LU5lFcxospQ"params = {"grant_type" : "client_credentials","client_id" : APIKey,"client_secret" : SecretKey,}response = requests.post(url, timeout=10, params=params)jsondata = json.loads(response.text)print(jsondata)
打印：
这里比较重要，需要我们记住的字段是 access_token，之后需要调用其他API的时候，要用到。expires_in是有效时间，这个时间过去了，获取到的token就无效了，按照常理是需要使用refresh_token来重新刷新token的，youtube等是这样处理的。

如果不熟悉python操作json的话，这样就可以取到access_token的val：
access_token = jsondata["access_token"]print("##########################")print(access_token)
打印：

结合上面获取到的json中的token,就可以继续下一步了：
定义了一个msg为发送的消息，然后再收到一个消息来接收
# 二、发送chat消息msg="你好，请问你是谁？"recv_msg = ""_url = "https://aip.baidubce.com/rpc/2.0/ai_custom/v1/wenxinworkshop/chat/eb-instant"# 1、发送params = { "access_token" : access_token}body = {"messages": [{"role": "user","content": msg}]}headers = { "Content-Type": "application/json" }json_data = json.dumps(body, indent=4)response = requests.post(_url, timeout=10, params=params, data=json_data ,headers=headers)# 转成JSONjsondata = json.loads(response.text)print(jsondata)recv_msg = jsondata["result"]# 2、接受&处理 消息print("收到了: ",recv_msg)
