我尝试将图片上传到图片识别API，但我得到的是NSHTTPURLResponse我得到的。
<NSHTTPURLResponse: 0x12f7ce4e0> { URL: https:/api.vize.ai/v1/classify/ } { status code: 400, headers {
Allow = "POST, OPTIONS";
Connection = "keep-alive";
"Content-Language" = en;
"Content-Length" = 37;
"Content-Type" = "application/json";
Date = "Wed, 21 Feb 2018 12:24:17 GMT";
"Referrer-Policy" = "strict-origin";
Server = "nginx/1.13.7";
"Strict-Transport-Security" = "max-age=31536000; includeSubDomains; preload";
Vary = "Accept, Host, Accept-Language, Cookie";
"X-Frame-Options" = DENY;
"X-UA-Compatible" = "IE=Edge,chrome=1";
"x-content-type-options" = nosniff;
"x-xss-protection" = "1; mode=block";
} }
我使用图像选择器选择图像，然后上传它。这是我的实现。
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info
{
// Dismiss image picker
[picker dismissViewControllerAnimated:YES completion:nil];
// Classify image
UIImage *image = [info objectForKey:@"UIImagePickerControllerEditedImage"];
// Request authorization
[PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {

}

} else {

NSLog(@"%@", httpResponse);
}

我的问题是什么？

使用afnetworking进行此操作。 这是工作代码：
-(void)uploadImagetoServer

//NSString *lastName=[NSString stringWithFormat:@"%@",[[NSUserDefaults standardUserDefaults] valueForKey:@"lastname"]];
NSString *fullname=[NSString stringWithFormat:@"%@ %@",[[NSUserDefaults standardUserDefaults] valueForKey:@"firstname"],[[NSUserDefaults standardUserDefaults] valueForKey:@"lastname"]];
NSString * type ;
NSString * userId = [NSString stringWithFormat: @"%@",[[NSUserDefaults standardUserDefaults] valueForKey:@"userid"]];
// lastName= [NSString stringWithFormat: @"%@ %@", firstName, lastName];
userInfoDict=[[NSMutableDictionary alloc] init];
[userInfoDict setValue:userId forKey:@"user_id"];
[userInfoDict setValue:fullname forKey:@"username"];
