上传图片文件至阿里云

首先cocoapod安装AliyunOSSiOS

一.请求阿里
//阿里云服务的sts认证请求

• (void)getAliSts {
  // 参数字典(服务器后台定义)
  NSMutableDictionary* dictParams = [NSMutableDictionary dictionaryWithCapacity:0];
  [dictParams setObject:@"446b0752c174e319281db45a8696ecf7" forKey:@"API[app_key]"];
  [dictParams setObject:@"json" forKey:@"API[output]"];
  [dictParams setObject:@"816b81d40440f2e3a8e1acfde1f7334e" forKey:@"API[access_token]"];
  [dictParams setObject:@"header" forKey:@"type"];
  //urlString:接口地址
  [NetworkTools requestWithMethod:GET urlString:@"http://wb.yunlala.com/bvb/alists/oss_put" parameters:dictParams callbackFunction:^(NSURLResponse *response, NSDictionary respondDic) {
  //服务器返回阿里相关配置信息

  2018-07-11 21:42:09.253987+0800 BWB[5459:3359590] {
  "result" : {
  "SecurityToken" : "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",

  "AccessKeySecret" : "BYRANG885aScWN8oCFGp4HqE4C9Dok48HBNMBe4nWKSM",
  "EndPoint" : "oss-cn-beijing.aliyuncs.com",
  "AccessKeyId" : "STS.NJqc2yx1zepGdEziLZMyynyvS"
  },
  "code" : "200"
  }
  */
  if ([respondDic[@"code"] integerValue]==200) {
  self.model = [MineAliOssModel mj_objectWithKeyValues:respondDic[@"result"]];
  //上传文件至阿里云
  [self uploadToAli];
  } else {

    }
  

  } errorCallbackFunction:^(NSError *error) {

  }];
  }

二.由服务器返回数据配置阿里上传相关上传配置
//传图片给阿里

• (void)uploadToAli {

  id credential = [[OSSFederationCredentialProvider alloc] initWithFederationTokenGetter:^OSSFederationToken *{
  OSSFederationToken * token = [OSSFederationToken new];
  token.tAccessKey = self.model.AccessKeyId;
  token.tSecretKey = self.model.AccessKeySecret;
  token.tToken = self.model.SecurityToken;
  token.expirationTimeInGMTFormat = self.model.Expiration;

    return token;
  

  }];
  OSSClientConfiguration * conf = [OSSClientConfiguration new];
  // 网络请求遇到异常失败后的重试次数
  conf.maxRetryCount = 3;
  // 网络请求的超时时间
  conf.timeoutIntervalForRequest =30;
  // 允许资源传输的最长时间
  conf.timeoutIntervalForResource =24 * 60 * 60;
  // 你的阿里地址前面通常是这种格式 ：http://oss……
  OSSClient *client = [[OSSClient alloc] initWithEndpoint:self.model.EndPoint credentialProvider:credential];
  OSSPutObjectRequest *putRequest = [OSSPutObjectRequest new];
  putRequest.bucketName = self.model.BucketName;
  self.imagePathStr = [self getimagePathStr];//文件名,自定义
  putRequest.objectKey = self.imagePathStr;
  putRequest.uploadingData = UIImageJPEGRepresentation(self.imgOrg, 1); // 直接上传NSData
  putRequest.uploadProgress = ^(int64_t bytesSent,int64_t totalByteSent, int64_t totalBytesExpectedToSend) {

    NSLog(@" %lld,  %lld,  %lld", bytesSent, totalByteSent, totalBytesExpectedToSend);
  

  };

  OSSTask *putTask = [client putObject:putRequest];
  [putTask continueWithBlock:^id(OSSTask *task) {
  if (!task.error) {

        NSLog(@" upload object success!");
        OSSPutObjectResult * result = task.result;
        NSLog(@" result.requestId : %@",result.requestId);
        NSLog(@" result.httpResponseHeaderFields : %@",result.httpResponseHeaderFields);
        NSLog(@" result.eTag : %@",result.eTag);
        NSLog(@" result.serverReturnJsonString : %@",result.serverReturnJsonString);
        
        //上传头像至服务器
        [self uploadImage:self.imagePathStr];
        
        
    } else {
        
        NSLog(@" upload object failed, error: %@" , task.error);
    }
    return nil;
  

  }];

}

三.将文件名地址传给后台服务器

//上传头像地址至服务器

• (void)uploadImage:(NSString)imgStr {
  // 参数字典
  NSMutableDictionary dictParams = [NSMutableDictionary dictionaryWithCapacity:0];
  [dictParams setObject:APP_KEY forKey:@"API[app_key]"];
  [dictParams setObject:@"816b81d40440f2e3a8e1acfde1f7334e" forKey:@"API[access_token]"];
  [dictParams setObject:@"json" forKey:@"API[output]"];
  [dictParams setObject:@"oauth2" forKey:@"API[auth_type]"];
  [dictParams setObject:@"user" forKey:@"mod"];
  [dictParams setObject:@"edit" forKey:@"code"];
  [dictParams setObject:imgStr forKey:@"header"];

  NSString* urlStr = [NSString stringWithFormat:@"%@/api.php", DomainName];
  [NetworkTools requestWithMethod:POST urlString:urlStr parameters:dictParams callbackFunction:^(NSURLResponse *response, NSDictionary *respondDic) {
  if ([respondDic[@"code"] integerValue]==200) {
  NSLog(@"上传头像地址至服务器--------------");
  MineInfoModel *info = [MineInfoModel mj_objectWithKeyValues:respondDic[@"result"]];
  self.infoModel.aboutme = info.aboutme;
  [self.tableView reloadData];

    } else {
        
    }
  

  } errorCallbackFunction:^(NSError *error) {

  }];
  }

//获取图片路径名,服务器后台自己定制规则,md5路径

• (NSString *)getimagePathStr {
  NSData *imageData = UIImageJPEGRepresentation(self.imgOrg, 1);
  NSString *name = [imageData md5String];
  NSRange range;
  range.location = 27;
  range.length = 1;
  NSString *str1 = [name substringWithRange:range];
  range.location = 13;
  range.length = 1;
  NSString *str2 = [name substringWithRange:range];
  range.location = 5;
  range.length = 1;
  NSString *str3 = [name substringWithRange:range];
  range.location = 19;
  range.length = 1;
  NSString *str4 = [name substringWithRange:range];
  NSString *path = [NSString stringWithFormat:@"%@%@/%@%@/%@.jpg",str1,str2,str3,str4,name];
  return path;
  }
