有人 回答么？ id credential = [[OSSFederationCredentialProvider alloc] initWithFederationTokenGetter:^OSSFederationToken *{ OSSFederationToken * token = [OSSFederationToken new]; token.tAccessKey = accessKey; token.tSecretKey = secretKey; token.tToken = tToken; return token; }]; OSSClientConfiguration * conf = [OSSClientConfiguration new]; conf.maxRetryCount = 2; conf.timeoutIntervalForRequest = 30; self.client = [[OSSClient alloc] initWithEndpoint:ENDPOINT credentialProvider:credential clientConfiguration:conf]; OSSPutObjectRequest * put = [OSSPutObjectRequest new]; // 必填字段 put.bucketName = bucketName; put.objectKey = key; put.uploadingData = data; if (option) { put.uploadProgress = ^(int64_t bytesSent, int64_t totalByteSent, int64_t totalBytesExpectedToSend) { // 当前上传段长度、当前已经上传总长度、一共需要上传的总长度 这里怎么不走 }; } if (option.callbackParam) { put.callbackParam = option.callbackParam; } if (option.params) { put.callbackVar = option.params; } OSSTask * putTask = [self.client putObject:put]; [putTask continueWithBlock:^id(OSSTask *task) { if (!task.error) { NSLog(@'upload object success!'); } else { NSLog(@'upload object failed, error: %@' , task.error); } return nil; }]; 有人解决么
