  2. 但是我传递的雀氏是json啊

    /** 删除用户接口 POST /api/user/delete */
    export async function deleteUser(body: number, options?: { [key: string]: any }) {
    return request<API.LoginResult>('/api/user/delete', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    data: body,
    ...(options || {}),
    });
    }
  3. 用postman等一系列的东西,测出来接口确实是没写错的

  4. github查找issues,方法试了都没用

  5. 谷歌、百度、csdn搜索关键词,用许多都与全局响应拦截有关

  6. 重新思考,得出结论,下面是我之前写的

    /**
    * 所有请求拦截器
    */
    request.interceptors.request.use((url, options): any => {
    console.log(`执行了请求拦截器 url={}`,url)
    return {
    url,
    options: {
      ...options,
    },
    headers: {
    }
    };
    });

    传入了一个空的headers,导致了之前接口传入的‘'Content-Type': 'application/json',’被覆盖成空,请求使用默认的Content-Type,格式错误。

虽然说着简单但找了我快两个小时T~T

感谢您的收看~
