拿element plus UI库举例，（不使用element plus的话js方法通用）：

<template>

    <el-upload class="upload-demo"
    :http-request="myUploadHttp" 
    action="https://run.mocky.io/v3/9d059bf9-4660-45f2-925d-ce80ad6c4d15"
    >
    </el-upload>
</template>

<script>

let myId = '95462445967354'

// 自定义上传文件(携带token和id)
const myUploadHttp = (options: any) => {
    console.log(options);
    if (!options) return;

    let Authorization = localStorage.getItem("Authorization");//请求头添加token权限
    const formData = new FormData();
    formData.append("file", options.file);
    formData.append("id", myId);//参数添加id


    const xhr = new XMLHttpRequest();
    xhr.open(options.action.method || "post", options.action, true);
    xhr.upload.onprogress = options.onProgress;
    xhr.onload = () => {
        if (xhr.status === 200) {
            options.onSuccess(JSON.parse(xhr.responseText));
        } else {
            options.onError();
        }
    };
    xhr.setRequestHeader("Authorization", `${Authorization}`); // 设置token权限
    xhr.send(formData);
    // 其他方法...
};

</script>
