使用AFHTTPClient的AFNetworking上传图片
使用AFHTTPClient的AFNetworking上传图片
提问于 2016-05-09 14:02:16
我的问题是为什么AFHTTPClient上传图片很慢。我正在使用下面的代码上传
NSData *imageToUpload = UIImageJPEGRepresentation(uploadedImgView.image, 1.0);
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:keyParameter, @"keyName", nil];
AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://------"]];
NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"API name as you have" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData: imageToUpload name:@"image" fileName:@"temp.jpeg" mimeType:@"image/jpeg"];
}];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSDictionary *jsons = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:nil];
//NSLog(@"response: %@",jsons);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
if([operation.response statusCode] == 403)
{
//NSLog(@"Upload Failed");
return;
}
//NSLog(@"error: %@", [operation error]);
}];
[operation start];回答 1

可能发生是您的图像较大且需要时间上载，或者您可以使用最新的AFNetworking并可以在上载图像时跟踪进度。
NSData *imageToUpload = UIImageJPEGRepresentation(uploadedImgView.image, 1.0);
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:keyParameter, @"keyName", nil];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];
NSString *URLtoCall = @"API name as you have";
[manager POST:URLtoCall parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
[formData appendPartWithFileData:imageToUpload name:@"image" fileName:@"temp.jpeg" mimeType:@"image/jpeg"];
} progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
