android客户端直传文件到阿里云OSS服务器详细流程代码

本文主要是介绍android客户端直传文件到阿里云OSS服务器详细流程代码，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

 

1.阿里云官方文档

https://help.aliyun.com/document_detail/31920.html?spm=a2c4g.11186623.2.12.2a1cbdce9IWQFh#title-zp8-uz7-br6  

 

2.拼接后的地址

3.后台返回的数据格式必须解析如下：

接口：http://api.chongdm.com/gateway/oss/getOssToken
//正确返回
{"StatusCode":200,"AccessKeyId":"STS.3p***dgagdasdg","AccessKeySecret":"rpnwO9***tGdrddgsR2YrTtI","SecurityToken":"CAES+wMIARKAAZhjH0EUOIhJMQBMjRywXq7MQ/cjLYg80Aho1ek0Jm63XMhr9Oc5s˙∂˙∂3qaPer8p1YaX1NTDiCFZWFkvlHf1pQhuxfKBc+mRR9KAbHUefqH+rdjZqjTF7p2m1wJXP8S6k+G2MpHrUe6TYBkJ43GhhTVFMuM3BZajY3VjZWOXBIODRIR1FKZjIiEjMzMzE0MjY0NzM5MTE4NjkxMSoLY2xpZGSSDgSDGAGESGTETqOio6c2RrLWRlbW8vKgoUYWNzOm9zczoqOio6c2RrLWRlbW9KEDExNDg5MzAxMDcyNDY4MThSBTI2ODQyWg9Bc3N1bWVkUm9sZVVzZXJgAGoSMzMzMTQyNjQ3MzkxMTg2OTExcglzZGstZGVtbzI=","Expiration":"2017-12-12T07:49:09Z",
}
//错误返回
{"StatusCode":500,"ErrorCode":"InvalidAccessKeyId.NotFound","ErrorMessage":"Specified access key is not found."
}

 3.app端上传文件路径，需要自己拼接

private var stsServer: String = "http://api.chongdm.com/gateway/oss/getOssToken"   
private  var oss: OSS? = nullfun initOSS() {        val credentialProvider: OSSCredentialProvidercredentialProvider = OSSAuthCredentialsProvider(stsServer)val conf = ClientConfiguration()conf.connectionTimeout = 15 * 1000 // 连接超时，默认15秒conf.socketTimeout = 15 * 1000 // socket超时，默认15秒conf.maxConcurrentRequest = 5 // 最大并发请求书，默认5个conf.maxErrorRetry = 2 // 失败后最大重试次数，默认2次oss = OSSClient(applicationContext, endpoint, credentialProvider, conf)}
fun postToOss(path: String) {val OssPath = "zhaozhuang/" + DateUtils.getCurrentDataDefaultString()+"/"+TimeUtils.getNowMills()+".png"// 构造上传请求。val put =PutObjectRequest(bucketName, OssPath, path)// 异步上传时可以设置进度回调。put.progressCallback = OSSProgressCallback { request, currentSize, totalSize ->Log.d("PutObject","currentSize: $currentSize totalSize: $totalSize")}val task: OSSAsyncTask<*> = oss!!.asyncPutObject(put,object : OSSCompletedCallback<PutObjectRequest?, PutObjectResult> {override fun onSuccess(request: PutObjectRequest?,result: PutObjectResult) {Log.d("PutObject", "UploadSuccess")Log.d("ETag", result.eTag)Log.d("RequestId", result.toString())}override fun onFailure(request: PutObjectRequest?,clientExcepion: ClientException,serviceException: ServiceException) {// 请求异常。clientExcepion?.printStackTrace()if (serviceException != null) {// 服务异常。Log.e("ErrorCode", serviceException.errorCode)Log.e("RequestId", serviceException.requestId)Log.e("HostId", serviceException.hostId)Log.e("RawMessage", serviceException.rawMessage)}}})}
