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
