最近在写纯血鸿蒙的APP需要用到oss上传照片之前的客户端 Android 和 IOS 都已经实现了获取的阿里云签名的上传地址是服务端实现的相信大部分公司都是这样的模式服务端也是调用阿里云的SDK来实现的这里就不说了。
一、获取阿里云的上传地址的服务端响应大致如下

}上面我们服务端是封装过的其中 uploadUrl 就是获取的上传oss需要的 urlcontentType也是上传附件需要的参数。url 是上传后可以直接显示图片的 url。
二、使用服务端返回的oss上传附件的对象进行文件上传 async putToOssServer(ossUrl: string, contentType: string, imageUrl: string) {const fileInfo await fs.open(this.imgPath, fs.OpenMode.READ_ONLY);const fileStat await fs.stat(fileInfo.fd);console.info(file name: , fileInfo.name);const data new ArrayBuffer(fileStat.size);await fs.read(fileInfo.fd, data);await fs.close(fileInfo.fd);try {// 使用PutObject方法上传文件const httpRequest http.createHttp()httpRequest.request(ossUrl, {method: http.RequestMethod.PUT,header: {Content-Length: fileStat.size,Content-Type: contentType},extraData: data,connectTimeout: 10000,readTimeout: 10000}, (error: Error, response: http.HttpResponse) {// error 为空表明接口调用成功if (!error) {console.log(接口请求成功ossImgUrl imageUrl, response ${response.result})this.ossImgUrl imageUrl} else {console.log(接口请求失败url ossUrl, 错误信息 ${JSON.stringify(error)})}// 销毁请求httpRequest.destroy()})console.info(success putObject);} catch (err) {console.info(putObject request error: JSON.stringify(err));// throw err;}}通过上面的方法就可以实现 oss 文件上传了。 使用PutObject方法上传文件url 对应的是上面的 uploadUrlcontentType 也是上面服务端返回的 imageUrl 对应的是 服务端返回的字段 url 。
遇到的坑
contentType 我直接写死的 application/json应该是用服务端返回的 contentType。显示照片我也用的是 uploadUrl导致报如下的错误
SignatureDoesNotMatch: The request signature we calculated does not match the signature you provided. Check your key and signing method应该是使用服务端返回的字段 url 。
好了最后就大功告成了。
