我在数据库和云存储中放入了张图片，但是在获取下载链接的时候获取不到，报错"storage_sign_param_invalid"的错误。
{"errcode":0,"errmsg":"ok","file_list":[{"fileid":"cloud://dev-7q032.6465-dev-1300969255/swiper/1583332218903.jpg","download_url":"","status":1,"errmsg":"STORAGE_SIGN_PARAM_INVALID"}]}
下面是我的demo代码：
let ACCESS_TOKEN =await getAccessToken();
const DownloadURL = `https://api.weixin.qq.com/tcb/batchdownloadfile?access_token=${ACCESS_TOKEN}`;
let fileList=[{
fileid:'cloud://dev-7q032.6465-dev-7q032-1300969255/swiper/1583332218903.jpg',
max_age:7200
}]
let options= {
method: 'POST',
url:DownloadURL,
body: {
"env": ENV,
"file_list":fileList
},
json:true
}
return await rp(options)
.then(res=>{
console.log('批量下载地址'+JSON.stringify(res))
return res
})
请大佬告知是哪里问题
你是用 http api上传的图片，然后再下载的吗
let params = {method: 'POST',headers:{'content-type':'multipart/form-data'},uri:response.url,formData:{key:path,Signature:response.authorization,"x-cos-security-token":response.token,"x-cos-meta-fileid":response.file_id,file:fs.createReadStream(file.path)}}await rp(params).then(response=>{console.log('上传的response'+JSON.stringify(response));})
