2. 原因分析

3. 解决方案

import requests
import json

# 配置API请求
url = "YOUR_DMXAPI_ENDPOINT"  # 替换为实际端点
payload = {
    "model": "gemini-3.1-pro-preview",
    "messages": [{"role": "user", "content": "Hello"}]  # 替换为实际参数
}

try:
    # 发送请求并检查状态码
    response = requests.post(url, json=payload, timeout=10)
    response.raise_for_status()  # 非200状态码直接抛异常
    
    # 安全解析JSON
    try:
        result = response.json()
        print("解析成功:", result)
    except json.JSONDecodeError:
        print(f"JSON解析失败！响应内容（前200字）: {response.text[:200]}")
        raise  # 或自定义错误处理

except requests.exceptions.RequestException as e:
    print(f"API请求失败: {str(e)}")
