data.append("file", _this.file); //
data.append("token", _this.postData.token);
data.append("key", _this.postData.key);
axios.post(_this.url, data).then(function(res) {
console.log(res);
})
key and hash have been returned in res, but why do I see this file in the background of Qiniu, but I can"t show the picture and file when previewing?
