图床上传

由于业务需要用到图床上传于是找到了一个比较好用的图床，https://imgbb.com/

这里仅记录通过API上传

1. 通过邮箱注册账号
2. 注册完以后参考文档 https://api.imgbb.com/

先获取key: 6f76b23f17axxxxxxxxxx

上传图片接口: https://api.imgbb.com/1/upload

有四个参数

const data = {
    key: '', // 你申请到的key
    image: '', // 所要上传的图片 可以是base64 也可以是一个url  也可以是binary file
    name: '', // 图片名称 该名称是访问外链的图片名称 同名将覆盖
    expiration: 60 // 过期时间， 60-15552000 单位：秒数
}

这里例子是使用如果是在云函数中调用

const key = '6f76b23f17axxxxxxxxxx'
const baseUrl =  `https://api.imgbb.com/1/upload?key=${key}`
const res = await uniCloud.httpclient.request(baseUrl, {
    method: 'POST',
    dataAsQueryString:false,
    data: {
        key: key,
        image: event.base64,  // 如果是base64 必须使用 post
        name: '60s1',
        expiration: 600
    },
    headers: {
        "Content-Type": "application/x-www-form-urlencoded" // 否则不会将base64上传
    },
    timeout: 30*1000,
    dataType: 'json'
})

返回的结果
