但是 后台没有接收到，是后台配置的原因，还是iOS端的原因？
NSString *endpoint = @"http://chongpai.oss-cn-beijing.aliyuncs.com";
    // 明文设置secret的方式建议只在测试时使用，更多鉴权模式参考后面链接给出的官网完整文档的`访问控制`章节
    id<OSSCredentialProvider> credential = [[OSSPlainTextAKSKPairCredentialProvider alloc] initWithPlainTextAccessKey:AccessKey
                                                                                                            secretKey:SecretKey];
    client = [[OSSClient alloc] initWithEndpoint:endpoint credentialProvider:credential];
    OSSPutObjectRequest * put = [OSSPutObjectRequest new];
    // required fields
#warning 参数设置
    put.bucketName = @"chongpai";
    NSString *objectKeys = [NSString stringWithFormat:@"789/%@.jpg",[self getTimeNow]];
    
    put.objectKey = objectKeys;
//    put.uploadingFileURL = [NSURL fileURLWithPath:fullPath];
    put.uploadingData = self.imageData;
    put.uploadProgress = ^(int64_t bytesSent, int64_t totalByteSent, int64_t totalBytesExpectedToSend) {
        NSLog(@"%lld, %lld, %lld", bytesSent, totalByteSent, totalBytesExpectedToSend);
    };

    OSSTask * putTask = [client putObject:put];
这是 代码中参数的配置
