【iOS】 视频压缩上传

之前写过图片上传PHP服务器，今天把接口稍微改了一下，把视频上传的代码贴出来，目前上传功能已经调通，视频的压缩代码上似乎并不完善，后续会完善压缩部分的代码；

- (void)convertVideoWithURL:(NSURL *)url
{
    NSDate *date = [NSDate date];
    NSDateFormatter *dateformatter = [[NSDateFormatter alloc]init];
    [dateformatter setDateFormat:@"YYYY-MM-dd-HH-mm-ss"];
    NSString *dateName = [dateformatter stringFromDate:date];
    NSString *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES).firstObject;
    NSString *pathName = [path stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.mp4",dateName]];
    NSLog(@"沙盒：%@",pathName);
    //转码配置
    AVURLAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
    AVAssetExportSession *exportSession= [[AVAssetExportSession alloc] initWithAsset:asset presetName:AVAssetExportPresetMediumQuality];
    exportSession.shouldOptimizeForNetworkUse = YES;
    exportSession.outputURL = [NSURL fileURLWithPath:pathName];
    exportSession.outputFileType = AVFileTypeMPEG4;
    [exportSession exportAsynchronouslyWithCompletionHandler:^{
        int exportStatus = exportSession.status;
        switch (exportStatus)         {
            case AVAssetExportSessionStatusFailed:
            {
                // log error to text view
                NSError *exportError = exportSession.error;
                NSLog (@"AVAssetExportSessionStatusFailed: %@", exportError);
                [SVProgressHUD showErrorWithStatus:@"视频压缩失败"];
                [SVProgressHUD dismissWithDelay:1.0];
                break;
            }
            case AVAssetExportSessionStatusCompleted:
            {
                self.videoData = [NSData dataWithContentsOfFile:pathName];
                
                [[NetTool shareDL]upLoadVideoWithURL:@"http://192.168.1.102/php/image.php" paremeter:nil data:self.videoData videoName:[NSString stringWithFormat:@"%@.mp4",dateName] progress:^(NSProgress * _Nonnull uploadProgress) {
                    
                    [SVProgressHUD showProgress:1.0*uploadProgress.completedUnitCount/uploadProgress.totalUnitCount status:@"正在上传"];
                    NSLog(@"正在上传%f%%",(1.0*uploadProgress.completedUnitCount/uploadProgress.totalUnitCount)*100);
                    
                } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
                    [SVProgressHUD showSuccessWithStatus:@"上传成功"];
                    [SVProgressHUD dismissWithDelay:1.0];
                } fail:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
                    [SVProgressHUD showErrorWithStatus:@"上传失败"];
                    [SVProgressHUD dismissWithDelay:1.0];
                }];
                
            }
        }
    }];
}

[manager POST:url parameters:parameter constructingBodyWithBlock:^(id  _Nonnull formData) {
        [formData appendPartWithFileData:videoData name:@"upimage" fileName:videoName mimeType:@"video/mp4"];
    } progress:^(NSProgress * _Nonnull uploadProgress) {
        progress(uploadProgress);
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        success(task,responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        fail(task,error);
    }];
