报错分析
1.错误翻译
原文：API 返回的 completion 类型错误：<class 'str'>
译文：API返回的completion类型错误：类型为字符串（<class 'str'>）
2.原因分析
Content-Type错误或请求参数/路径错误，导致服务器返回HTML而非目标completion数据。3. 解决方案
import requests
def get_valid_completion(api_url, payload, headers):
response = requests.post(api_url, json=payload, headers=headers)
# 校验响应类型（核心修复）
if "text/html" in response.headers.get("Content-Type", ""):
raise ValueError(f"API返回HTML而非数据：{response.text[:200]}...")
return response.json() # 正常解析JSON
# 使用示例（替换为真实参数）
api_url = "https://dmxapi.cn/v1/chat/completions" # 正确端点
payload = {"model": "gpt-3.5-turbo", "messages": [{"role": "user", "content": "你好"}]}
headers = {"Authorization": "Bearer YOUR_KEY", "Content-Type": "application/json"}
try:
result = get_valid_completion(api_url, payload, headers)
except ValueError as e:
print(f"错误：{e}")
4. 预防措施
Content-Type（如application/json），非预期类型立即抛错。 ---
注：若仍报错，需检查API密钥有效性、模型名称是否正确，或联系DMXAPI支持确认服务状态。
