在公司的项目中使用七牛来进行用户头像的存储。
上传头像的实现步骤如下
首先从后端获取QN的key和token
- (void)getTokenFromQN{
NSDictionary *parameter = @{ @"type":@"avatar", };
[[QLBaseNetWorking shareManager]QL_Get:[NSString stringWithFormat:@"%@%@",API_AHead,API_AGetQiniuToken] parameters:parameter resultWithBlock:^(BOOL success, id responseData) {
if (success) {
NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingAllowFragments error:nil];
if (((NSNumber *)[dic objectForKey:@"code"]).intValue == 0) {
NSDictionary *dataDic = [dic objectForKey:@"item"];
self.domain = dataDic[@"key"];//七牛key
self.token = dataDic[@"uploadToken"];//七牛token
[self uploadImageToQNFilePath:[self getImagePath:self.pickImage]];
}
}
}];
}
然后使用QNUploadManager进行文件上传
-(void)uploadImageToQNFilePath:(NSString *)filePath
{
QNUploadManager *upManager = [[QNUploadManager alloc] init];
QNUploadOption * uploadOption = [[QNUploadOption alloc] initWithMime:nil progressHandler:^(NSString *key, float percent) {
PTTLog(@"percent == %.2f",percent);
} params:nil checkCrc:NO cancellationSignal:nil];
PTTLog(@"%@%@",filePath,self.token);
[upManager putFile:filePath key: self.domain token:self.token complete:^(QNResponseInfo *info, NSString *key, NSDictionary *resp) {
[self showTextOnly:@"头像上传成功"];
[UserManager shareEngine].token.headimgurl =[[resp objectForKey:@"item"] objectForKey:@"imgUrl"];
[[UserManager shareEngine] loginWithUserModel:[UserManager shareEngine].token];
[self dataFactory:[UserManager shareEngine].token.headimgurl name:[UserManager shareEngine].token.nickname phone:[UserManager shareEngine].token.phone];
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath,nil] withRowAnimation:UITableViewRowAnimationFade];
} option:uploadOption];
}
上述方法是使用本地保存的图片地址来进行上传操作，还有一种方法直接上传图片的数据
- (void)uploadWithFile:(NSString *)file withProgress:(QNUpProgressHandler)progress success:(void(^)(NSString*url))success failure:(void(^)())failure {
UIImage *getImage = [UIImage imageWithContentsOfFile:file];
QNUploadOption *option = [[QNUplLBHTTPRequestoadOption alloc] initWithMime:nil progressHandler:progress params:nil checkCrc:NO cancellationSignal:nil];
//先获取token
[LBHTTPRequest postImage:[LBHTTPRequest getUserId] token:[LBHTTPRequest getUserToken] userType:@"1" fileExt:@"png" SuccessBlock:^(BOOL isSuccess, NSDictionary *resultDic) {
if (isSuccess) {
NSString * token = resultDic[@"uploadToken"];
QNUploadManager *upManager = [[QNUploadManager alloc] init];
NSData *data;
if (UIImagePNGRepresentation(getImage) == nil){
data = UIImageJPEGRepresentation(getImage, 1);
} else {
data = UIImagePNGRepresentation(getImage);
}
[upManager putData:data key:resultDic[@"fileKey"] token:token
complete: ^(QNResponseInfo *info, NSString *key, NSDictionary *resp) {
[SVProgressHUD dismiss];
// isLoadLogo = NO;
if([resp[@"result"] intValue] == 200){
[LBUploadManager sharedInstance].imageUrl = resp[@"fileUrl"];
success([LBUploadManager sharedInstance].imageUrl);
}
} option:option];
}
}];
}
上传多张图片到七牛，利用简单的异步处理多个图片上传
并且在用户使用手机网络的时候进行提示
//上传多张图片
- (void)uploadImagesWithFileArray:(NSMutableArray *)fileArray progress:(void(^)(CGFloat))progress success:(void(^)(NSString *))success failure:(void(^)())failure {
//判断网络状态
AFNetworkReachabilityManager *netStatus = [AFNetworkReachabilityManager sharedManager];
[netStatus startMonitoring];
[netStatus setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
if (status == AFNetworkReachabilityStatusNotReachable) {//无网络连接
[SVProgressHUD showWithStatus:@"当前无网络连接"];
}
if (status == AFNetworkReachabilityStatusReachableViaWWAN) { //手机自带网络
//提示用户是否继续进行上传图片
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"友情提示" message:@"当前使用的手机流量,您是否继续?" delegate:[LBUploadManager sharedInstance] cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
[alert show];
}
if (status == AFNetworkReachabilityStatusReachableViaWiFi) { //wifi
//1.获取所有的图片
NSMutableArray *imageArray = [[LBUploadManager sharedInstance]getImageArrayWithFileArray:fileArray];
dispatch_queue_t queue = dispatch_get_global_queue(0, 0);
dispatch_async(queue, ^{
for (int i = 0; i < imageArray.count; i ++ ) {
dispatch_async(queue, ^{ //上传头像
[[LBUploadManager sharedInstance]uploadWithFile:imageArray[i] withProgress:^(NSString *key, float percent) {
progress(percent);
} success:^(NSString *url) {
success(url);
//获取studentId
NSString *key = [[LBUploadManager sharedInstance].fileArray[i] allKeys].lastObject;
[LBHTTPRequest PostUpdataStudentImageWithStudentId:key withStudentImage:url andSuccessBlock:^(BOOL isSuccess, NSDictionary *resultDic) {
if (isSuccess) {
[[NSNotificationCenter defaultCenter]postNotificationName:@"refresh" object:nil];
[[NSNotificationCenter defaultCenter]postNotificationName:@"updataStudentData" object:nil];
}
[[NSUserDefaults standardUserDefaults]setObject:@"1" forKey:imageArray[i]];
[[LBUploadManager sharedInstance].fileArray removeObject:imageArray[i]];
}];
} failure:^{
}];
});
}
});
}
if (status == AFNetworkReachabilityStatusUnknown) { //未知网络
}
}];
}
