I have created one API and it is adding data in database, with values and image.

In postman I am calling that and setting image in form-data and other values in raw in JSON but still in image I am getting null value in source code object. Below are screenshots.

I want help in two things :

1. Why I am getting Null in image value in source code, please check below image.
2. How can I send both image and data using postman, check below screenshots is that ok what I have tried ?

First screenshot is of postman in which I am sending data in json format :

Second screenshot is of postman in which I am sending image in same request in postman

Now in third image you can see in Image it is showing Null instead of values.

So I am not getting why image is coming null..Below is code for this

public async Task<int> Create(UserPreference _object)
{
   if(_object.Image != null)
   {
       var webRootPath = hostingEnv.WebRootPath;
       var fileName = Path.GetFileName(_object.Image.FileName);
       var filePath = Path.Combine(hostingEnv.WebRootPath, "images\\User", fileName);

       using(var fileStream = new FileStream(filePath, FileMode.Create))
       {
          await _object.Image.CopyToAsync(fileStream);
       }

       _object.ImagePath = filePath;
   }
   
   var obj = await applicationDbContext.UserPreferences.AddAsync(_object);
   return applicationDbContext.SaveChanges();
}

You cannot send both form-data and JSON body at the same time To solve your problem send image and your other information as form-date For more details see the screenshot

CodePudding user response：

To send image and data using Postman you have to use form-data content type.

Select body => form-data. Column key has a selector. For a file select file-type and select file. To send data in the same time you will have to separate your json in key value pair.
