分享扩展不上传全尺寸图片

i am developeing share extension for my iOS application. i had really done every thing but the problem is that my code is only working for small images but when i upload image taken from device camer then uploading fails and only text get uploded.

我正在为我的iOS应用程序开发共享扩展。我确实做过每件事，但问题是我的代码只适用于小图像，但当我上传从设备摄像头拍摄的图像时，上传失败，只有文字被上传。

- (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];
}

i update my code to this and i check on server my request never reaches to server. I am using this code

我更新了我的代码，并检查服务器，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];

3 个解决方案

#1

Extensions aren't allowed their own cache disk space. Need to share with application

扩展不允许拥有自己的缓存磁盘空间。需要与应用程序共享

Uploading large image need cache disk space,so you upload failed.

上传大图片需要缓存磁盘空间，所以上传失败。

You need create url session with following codes:

您需要创建具有以下代码的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)

and then setting the app group both extension target and containing app.

然后设置app组扩展目标和包含app。

#2

You should be using a background NSURLSession since you are meant to dismiss the sharing UI as soon as possible by calling completeRequestByReturningItems on your NSExtensionContext instance.

您应该使用后台NSURLSession，因为您应该通过在NSExtensionContext实例上调用completerequestestestbyreturningitems来尽快取消共享UI。

#3

The problem is i am not using background session

问题是我没有使用后台会话

  NSURLSessionConfiguration *configuration= [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:configurationName];
