报错分析

1.错误翻译

原文：invalid params
译文：无效参数

2. 原因分析

3.解决方案

python
import requests
from pydantic import BaseModel, ValidationError
1. 用Pydantic定义参数Schema（强制校验）

class DmxApiParams(BaseModel):
    prompt: str  # 必填：提示词
    model: str   # 必填：模型名
    max_tokens: int = 100  # 可选：默认100
def call_dmxapi(params: dict):
    try:
        # 校验参数
        validated = DmxApiParams(params)
    except ValidationError as e:
        raise ValueError(f"参数无效：{e}") from e
    
    # 2. 发送合规请求
    url = "https://api.dmxapi.com/v1/your-endpoint"
    headers = {"Authorization": "Bearer YOUR_API_KEY"}
    response = requests.post(url, json=validated.dict(), headers=headers)
    response.raise_for_status()  # 抛出HTTP错误（含400详情）
    return response.json()
正确示例

valid_params = {"prompt": "Hello", "model": "dmx-7b"}
result = call_dmxapi(valid_params)
