##### 阿里云OSS 浏览器直传 [官方文档](https://help.aliyun.com/document_detail/64047.html?spm=a2c4g.11174283.6.1236.16ea7da2xmF0Zz) ##### 首先是签名 也是阿里推荐的 STS模式-即临时身份令牌 > 由服务器签发一次，然后客户端用此实例化OSS对象进行上传。 ``` // 获取STS签名 get_STS() { return new Promise(async (resolve, reject) => { let name = new Date().getTime() + Math.random(); let operate = "uploadImg"; let that = this; // 请求后端接口获取STS签名，此处为后端需要的参数，基本都是自定义的 也可不传。 let res = await get_STS({ name, operate, sign: crypto.MD5(name + operate + "bayinabayin888").toString() }); if (res.data.code != 200) { that.$alert(res.data.message || res.data.msg); } else { resolve(res.data.data); } }); } ``` ``` // 上传单图 let OSS = require('ali-oss'); // img_blob为选择的文件对象 async upload_img_to_oss(img_blob) { return new Promise(async (resolve, reject) => { let oss_sign = await this.get_STS(); let client = new OSS({ accessKeyId: oss_sign.AccessKeyId, accessKeySecret: oss_sign.AccessKeySecret, stsToken: oss_sign.SecurityToken, endpoint: "oss-cn-beijing.aliyuncs.com/", bucket: "xxx-test" }); let result = await client.put( "xxx/" + oss_sign.AccessKeyId, img_blob ); // console.log(result); resolve(result); }); } ```
