Hi to all,
Good day!

I'm having an issue regarding the PutAsJsonAsync and PostAsJsonAsync in consuming the rest api: "http://afs-test-redis99.afservice.org:8080/site/"

Operations: PUT

Name: addItem
Path: /api/cart/{id}/item
Query: store type
Parameters: item, quantity,key
Request Body: AnyObject(optional)

Example: In my postman, it is working correctly, when I tried to put/add new item:

"http://afs-test-redis99.afservice.org:8080/site/api/cart/51/item?item=COM1&store=PCM&type=active&quantity=5"

But when I tried to implement this in my mvc repository class

public async Task<Uri> SaveItemAsync(Item item)
       {
           client.BaseAddress = new Uri("http://afs-test-redis99.afservice.org:8080/site/");
           client.DefaultRequestHeaders.Accept.Clear();
           client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(        "application/json"));

           HttpResponseMessage response = await client.PutAsJsonAsync($"api/cart/{item.ID}/item?",$"item={item.ProductID}&store=PCM&type=active&{item.Quantity}");
           response.EnsureSuccessStatusCode();

           // return URI of the created resource.
           return response.Headers.Location;
       }

The result error is:

{StatusCode: 400, ReasonPhrase: 'Bad Request', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
  Connection: close
  Date: Tue, 13 Jun 2017 00:23:21 GMT
  Server: Apache-Coyote/1.1
  Content-Length: 1062
  Content-Language: en
  Content-Type: text/html; charset=utf-8
}}

Can anyone assist me what's wrong on my code, sorry I'm new to consuming the web api in my client application. Thank you very much in advance.

What I have tried:

It is working correctly in postman:

"http://afs-test-redis99.afservice.org:8080/site/api/cart/51/item?item=COM1&store=PCM&type=active&quantity=5"

But when I tried to implement this in my mvc repository class (c#)

public async Task<Uri> SaveItemAsync(Item item)
        {
            client.BaseAddress = new Uri("http://afs-test-redis99.afservice.org:8080/site/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(		"application/json"));
			
            HttpResponseMessage response = await client.PutAsJsonAsync($"api/cart/{item.ID}/item?",$"item={item.ProductID}&store=PCM&type=active&{item.Quantity}");
            response.EnsureSuccessStatusCode();

            // return URI of the created resource.
            return response.Headers.Location;
        }

The issue solved by this code:

public async Task<Uri> SaveItemAsync(Item item)
        {
            RunAsync();
            var path = $"api/cart/{item.ID}/item";
            var paramValues = $"?item={item.ProductID}&store=MAC&type=active&quantity={item.Quantity}";
            var query = path + paramValues;
            
            HttpResponseMessage response = await client.PutAsJsonAsync(query, new StringContent(item.ProductID, UnicodeEncoding.UTF8, "application/json"));

            if (response.IsSuccessStatusCode)
            {
                response.EnsureSuccessStatusCode();
            }
            else
            {
                response.ReasonPhrase.ToString();
            }

            // return URI of the created resource.
            return response.Headers.Location;
            
        }
