Постман ошибка 415

I am following the API instructions from Adam Freeman’s «Pro ASP.NET Core MVC 2». I have the following API controller class:

    [Route("api/[controller]")]
    public class ReservationController : Controller
    {
        private IRepository repository;

    public ReservationController(IRepository repo) => repository = repo;

    [HttpGet]
    public IEnumerable<Reservation> Get() => repository.Reservations;

    [HttpGet("{id}")]
    public Reservation Get(int id) => repository[id];

    [HttpPost]
    public Reservation Post([FromBody] Reservation res) =>
        repository.AddReservation(new Reservation
        {
            ClientName = res.ClientName,
            Location = res.Location
        });

    [HttpPut]
    public Reservation Put([FromBody] Reservation res) => repository.UpdateReservation(res);

    [HttpPatch("{id}")]
    public StatusCodeResult Patch(int id, [FromBody]JsonPatchDocument<Reservation> patch)
    {
        Reservation res = Get(id);
        if(res != null)
        {
            patch.ApplyTo(res);
            return Ok();
        }
        return NotFound();
    }

    [HttpDelete("{id}")]
    public void Delete(int id) => repository.DeleteReservation(id);
}

The text uses PowerShell to test the API but I would like to use Postman. In Postman, the GET call works. However, I cannot get the POST method to return a value. The error reads ‘Status Code: 415; Unsupported Media Type’

In Postman, the Body uses form-data, with:

key: ClientName, value: Anne
key: Location, value: Meeting Room 4

If I select the Type dropdown to «JSON», it reads «Unexpected ‘S'»

In the Headers, I have:

`key: Content-Type, value: application/json`

I have also tried the following raw data in the body, rather than form data:

{clientName="Anne"; location="Meeting Room 4"}

The API controller does work and return correct values when I use PowerShell. For the POST method, the following works:

Invoke-RestMethod http://localhost:7000/api/reservation -Method POST -Body (@{clientName="Anne"; location="Meeting Room 4"} | ConvertTo-Json) -ContentType "application/json"

I have used Jersey Restful API to create a web service and I have the below:

@POST
@Path("/process/")
@Consumes({MediaType.MULTIPART_FORM_DATA})
@Produces({MediaType.APPLICATION_JSON})
public Response process(@FormDataParam("upload") InputStream is, @FormDataParam("upload") FormDataContentDisposition formData);

I have used the following dependencies:

in ws-context.xml, I have this part:

Now to test this, I am using Postman app to send a Post request. Below is the content from the code window:

Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryxxxxxxxxx

------WebKitFormBoundaryxxxxxxxxx
Content-Disposition: form-data; name="upload"; filename="test.json"

I have already referred to several samples on google, like this , this, and this and I see that I have provided the parameters correctly but I still get 415 Unsupported Media Type error in Postman. I have several other web services in this project which consumes MediaType application/json so the project configuration shouldn’t be an issue.

Can somebody please shed some light as to what is wrong here.

UPDATE: Added additional details related to all jersey and WS related dependencies used and important content from the web.xml file

The error message displayed is ‘Status Code: 415; Unsupported Media Type’ when attempting to use form-data in the Body section of Postman. If the Type dropdown is changed to «JSON», it then displays «Unexpected ‘S'». The Headers section has been filled out and an attempt has been made to use raw data in the body instead of form-data. The API controller is functional and returns the correct values when using PowerShell. The following solution can be implemented when encountering this issue: in Postman, use the data entry with POST and JSON body, set it to a specific format, and quote both the key and value.

POSTMAN POST Request Returns Unsupported Media Type


Question:

As per the guidelines given in Adam Freeman’s «Pro
ASP.NET Core
MVC 2», I am implementing the API instructions. The API controller class that I am using is as follows: 

    [Route("api/[controller]")]
    public class ReservationController : Controller
    {
        private IRepository repository;
    public ReservationController(IRepository repo) => repository = repo;
    [HttpGet]
    public IEnumerable Get() => repository.Reservations;
    [HttpGet("{id}")]
    public Reservation Get(int id) => repository[id];
    [HttpPost]
    public Reservation Post([FromBody] Reservation res) =>
        repository.AddReservation(new Reservation
        {
            ClientName = res.ClientName,
            Location = res.Location
        });
    [HttpPut]
    public Reservation Put([FromBody] Reservation res) => repository.UpdateReservation(res);
    [HttpPatch("{id}")]
    public StatusCodeResult Patch(int id, [FromBody]JsonPatchDocument patch)
    {
        Reservation res = Get(id);
        if(res != null)
        {
            patch.ApplyTo(res);
            return Ok();
        }
        return NotFound();
    }
    [HttpDelete("{id}")]
    public void Delete(int id) => repository.DeleteReservation(id);
}

The API is initially tested with PowerShell, but I prefer using Postman. Although the GET call is successful in Postman, the POST method does not provide a return value. ‘
error reads
‘ and ‘
Status Code: 415; Unsupported Media Type
‘ are involved in this issue.

The
form-data
is utilized in Postman’s Body alongside: 

key: ClientName, value: Anne
key: Location, value: Meeting Room 4

Upon selecting «JSON» from the Type dropdown, an error message displays stating «Unexpected ‘S'».

In the Headers, I have: 

`key: Content-Type, value: application/json`

In addition, I have attempted utilizing the raw data within the body instead of using form data. 

{clientName="Anne"; location="Meeting Room 4"}

The API controller successfully operates and provides accurate results when executed through PowerShell. The POST method functions properly with the following code. 

Invoke-RestMethod http://localhost:7000/api/reservation -Method POST -Body (@{clientName="Anne"; location="Meeting Room 4"} | ConvertTo-Json) -ContentType "application/json"


Solution 1:

If you want to utilize Postman for POST requests with
JSON body
, then you must employ the

raw

data input and assign it the value of

application/json

. This will result in the following data format. 

{"clientName":"Anne", "location":"Meeting Room 4"}

Observe the usage of quotation marks for both the key and value.


Solution 2:

To optimize the use of the Patch method, it is advisable to structure the raw Body section of Postman accordingly. 

    {
        "op": "replace", "path": "/firstName" , "value": "FirstName",
    }

and data entry be application/json

Spring — Unsupported Media Type in postman, Sometimes in the request-BODY, you have to put (at the least) some empty brackets. Aka {} Http 415 Media Unsupported is responded back only when the content type header you are providing is not supported by the application. With POSTMAN, the Content-type header you are sending is Content type ‘multipart/form-data not application/json.

Postman «status»: 415, «error»: «Unsupported Media Type»


Question:

The aim was to establish a class that allowed for the inclusion of a customer (cliente) in a session (aula). 

@RequestMapping(value = "/aulas/{numero}/{numerocliente}", method = RequestMethod.PUT, consumes = MediaType.APPLICATION_XML_VALUE, produces = MediaType.APPLICATION_XML_VALUE)
public ResponseEntity

My Postman request is as follows, featuring

http://localhost:8080/api/aulas/1/23

.

and this is how it turns out: 

{
    "timestamp": "2020-04-25T00:12:02.300+0000",
    "status": 415,
    "error": "Unsupported Media Type",
    "message": "Content type 'text/plain' not supported",
    "path": "/api/aulas/1/23"
}


Solution:

Add your
content type
to the request header of your Postman. 

Content-Type application/xml

Unsupported Media Type» message: «Content type », But when I call method in POSTMAN it works with Content-type: application/json. const A Stack Overflow. About; Products For Teams; Stack Overflow Public 415, error: «Unsupported Media Type»,…} error: «Unsupported Media Type» message: «Content type » not supported» path: «/sample/» status: 415 timestamp: «2021-01

Postman. Issue with multipart/form-data (415 Unsupported Media Type)


Question:

While conducting a test using Postman, I encountered a problem with my endpoint that was configured for «multipart/form-data».

I possess a method that includes several fields along with a photo, which functions correctly with Swagger. 

[HttpPost]
public async Task MailPhoto([FromForm] MailwithPhoto mailWithPhoto)
{...}
public class MailwithPhoto 
{ 
  public string mail_message { get; set; } 
  public IFormFile photo_file { get; set; }
  public string userContact { get; set; }
  public string category { get; set; }
  public string userName { get; set; }
  public string method { get; set; }
}

enter image description here


Solution:

The key

message

must be changed to either

mail_message

or

mail_message

to ensure successful binding. Error code 415 commonly occurs as a result of issues with Content-Type or Content-Encoding, or from directly examining the data.

A functional demonstration is available, utilizing a .net core mvc project. Please refer to the following image:

.

result:

Unsupported Media Type 415, but in Postman works fine, Unsupported Media Type 415, but in Postman works fine. After registration user get a link, which consist of userId and token. When user click on it — angular project opens, then angular takes userId and token from link, and send a post method to backend for verifying email.

415 Unsupported Media Type when using Postman and Asp Web Api


Question:

When attempting to create a new item using Postman, I receive a 415 status code with the message »
unsupported media type
«. However, I am able to achieve the expected outcome when using the GetAll function. The following code is being used for this operation. 

[HttpPost]
public IActionResult Create([FromBody]TodoItem item)
{
    if (item == null)
    {
        return BadRequest();
    }
    _context.TodoItems.Add(item);
    _context.SaveChanges();
    return CreatedAtRoute("GetTodo", new { id = item.Id }, item);
}


Solution:

Try adding a header in Postman to avoid using the default content-type of «text/plain».

Your parameters should be sent in the body if you are utilizing the [
frombody
] tag.
