iOS上传图片和视频(base64和file)

By | 2019年8月26日

前言
iOS开发中经常会使用到图片和视频上传及保存到相册,下面我讲介绍视频图片的两种上传服务器的方法。以阿里云的OSS服务器为例。

友情提示:
上传图片方法在APP中使用很广泛,最好单独写一个图片上传的类,这样就很方便了。

base64上传图片:
NSString *strType = [GXToolClass getBase64Str:image];

    NSMutableDictionary *dic = [NSMutableDictionary dictionaryWithCapacity:1];

    [dic setValue:strType forKey:@"base64"];

    

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    [manager POST:[BASE_HOST stringByAppendingString:Http_Global_OneImage] parameters:dic progress:^(NSProgress * _Nonnull uploadProgress) {

        

    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

        if ([responseObject[GetCode] intValue] == 0) {

            NSDictionary *dic = responseObject[GetData];

            NSString *file = dic[@"file"];

            if (self.block) {

                self.block(file);

            }

        }else{

            [[AppDelegate getApp] showAlert:responseObject[GetNewMess] type:AlertViewType_Toast];

            if (self.otherBlock) {

                self.otherBlock(responseObject[GetNewMess]);

            }

        }

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

        if (self.failBlock) {

            [[AppDelegate getApp] showAlert:@"上传失败请稍后重试" type:AlertViewType_Toast];

            self.failBlock(@"上传失败请稍后重试");

        }

    }];

 

+(NSString *)getBase64Str:(UIImage *)ima //图片转成base64的 方法

{

    NSData *data = UIImageJPEGRepresentation(ima, 0.3);

    NSString *imageStyle = [self getImageStyle:data];

    NSString *str = [data base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

    str = [NSString stringWithFormat:@"data:image/%@;base64,%@", imageStyle, str];

    return str;

}

file视频上传:
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    manager.requestSerializer = [self getHttpHeader];

//    manager.responseSerializer.acceptableContentTypes = nil;

    

    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];

    

    [self beginLoading:@"上传中" view:self.view];

    [manager POST:[BASE_HOST stringByAppendingString:Http_Main_VideoUpLoad] parameters:dic constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

        

        NSString *strimageStyle = [GXToolClass getImageStyle:dataIma];

        [formData appendPartWithFileData:data1 name:@"file" fileName:_outputPath mimeType:@"mov"];

        [formData appendPartWithFileData:dataIma name:@"thumb" fileName:[NSString stringWithFormat:@"file.%@", strimageStyle] mimeType:strimageStyle];

 

    } progress:^(NSProgress * _Nonnull uploadProgress) {

 

    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

        [self stopLoading];

        if ([responseObject[GetCode] intValue] == 0) {

            [self.navigationController popViewControllerAnimated:YES];

        }

        [self showAlert:responseObject[GetMessage] type:AlertViewType_Toast];

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

        [self stopLoading];

        [self showAlert:@"上传失败请稍后重试" type:AlertViewType_Toast];

    }];

+(NSString *)getImageStyle:(NSData *)data//获取图片格式

{

    uint8_t c;

    [data getBytes:&c length:1];

    switch (c) {

        case 0xFF:

            return @"jpeg";

        case 0x89:

            return @"png";

        case 0x47:

            return @"gif";

        case 0x49:

        case 0x4D:

            return @"tiff";

        case 0x52:

            if ([data length] < 12) {

                return nil;

            }

            NSString *testString = [[NSString alloc] initWithData:[data subdataWithRange:NSMakeRange(0, 12)] encoding:NSASCIIStringEncoding];

            if ([testString hasPrefix:@"RIFF"] && [testString hasSuffix:@"WEBP"]) {

                return @"webp";

            }

            return nil;

    }

    return nil;

}

两种方法均可公用不在重复说明
