共享扩展程序未上传全尺寸图像

我正在为我的 iOS 应用程序开发共享扩展。我确实做了所有事情，但问题是我的代码仅适用于小图像，但是当我上传从设备摄像头拍摄的图像时，上传失败，只有文本被上传。

- (void)performUploadWith:(NSDictionary *)parameters imageFile:(UIImage *)image{

NSString *boundary = @"SportuondoFormBoundary";


//    NSURLSessionConfiguration *configuration= [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:configurationName];

//    NSURLSession *session=[NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
//    NSMutableURLRequest *request;//[NSURLRequest pho]

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
configuration.HTTPAdditionalHeaders = @{
                                        @"api-key"       : @"55e76dc4bbae25b066cb",
                                        @"Accept"        : @"application/json",
                                        @"Content-Type"  : [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary]
                                        };

NSURLSession *session=[NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];


NSMutableData *body = [NSMutableData data];


for (NSString *key in parameters)
{
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", key] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"%@\r\n", [parameters objectForKey:key]] dataUsingEncoding:NSUTF8StringEncoding]];

}

NSData *imageData = UIImageJPEGRepresentation(image, 0.8);
NSLog(@"imageDATE, %@", imageData);
if (imageData)
{
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", @"file"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[@"Content-Type: image/jpg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:imageData];
    [body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];




// Data uploading task. We could use NSURLSessionUploadTask instead of NSURLSessionDataTask if we needed to support uploads in the background
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@",kURLBase,kURLAddPostDL]];
NSLog(@"url %@",url);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10000];
request.HTTPMethod = @"POST";
request.HTTPBody = body;



NSURLSessionUploadTask *upload=[session uploadTaskWithRequest:request fromData:request.HTTPBody];
[upload resume];
}

我将代码更新为此，然后检查服务器，我的请求从未到达服务器。我正在使用这个代码

        NSInteger randomNumber = arc4random() % 1000000;
    NSURLSessionConfiguration *config = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:[NSString stringWithFormat:@"testSession.foo.%d", randomNumber]];
    config.sharedContainerIdentifier=kGroupNameToShareData;
  session = [NSURLSession sessionWithConfiguration:config delegate:self delegateQueue:nil];
  NSURLSessionUploadTask  *uploadTask = [session uploadTaskWithRequest:request fromFile:[NSURL        URLWithString:[NSString stringWithFormat:@"file://%@", dataSrcImagePath]]];

   [uploadTask resume];

不允许扩展拥有自己的缓存磁盘空间。需要与应用程序共享

上传大图片需要缓存磁盘空间，所以上传失败。

您需要使用以下代码创建 url 会话：

let configName = "com.shinobicontrols.ShareAlike.BackgroundSessionConfig"
let sessionConfig = NSURLSessionConfiguration.backgroundSessionConfigurationWithIdentifier(configName)
// Extensions aren't allowed their own cache disk space. Need to share with application
sessionConfig.sharedContainerIdentifier = "group.ShareAlike"
let session = NSURLSession(configuration: sessionConfig)

然后设置应用程序组扩展目标和包含应用程序。
