[Updated with imageNameStr]
While uploading your image data, it is necessary to send Name of the file.To generate a file Name, Here I've used Date and time.
Add the Code below the Line NSLog(#"reqData=%#",reqData);
====================
You have missed the formData Code.
Where as the image is the actual image in the below code.
NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
[formatter setDateFormat:#"yyyyMMddhhmmssSSS"];
NSString *imageNameStr = [NSString stringWithFormat:#"%#.jpg",[formatter stringFromDate:[NSDate date]]];
[sessionManager POST:appendURL
parameters:postParamDict
constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
if(image!=nil){
NSData * imageData = UIImageJPEGRepresentation(image,0.5f);
if(imageData!=nil){
[formData appendPartWithFileData:imageData
name:#"image"
fileName:imageNameStr
mimeType:#"image/jpg"];
}
}
}
progress:^(NSProgress * _Nonnull uploadProgress) {
}
success:^(NSURLSessionDataTask * _Nonnull task, id _Nonnull responseObject) {
NSLog(#"%#",responseObject);
if(success)
success (responseObject);
}
failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(#"error %#",error);
if(failure)
failure (error);
}]
