Hi I am a Web Api beginner am trying to call one api in another api in asp.net core 3.1. I created two solutions with diffrent port numbers. From httpclient method breakpoint is not going to external api methode.its returning a response as bad request please someone tell what i did wrong here?


getting like::::

{StatusCode: 400, ReasonPhrase: 'Bad Request', Version: 1.1, Content: System.Net.Http.HttpConnectionResponseContent, Headers: { Date: Fri, 05 Feb 2021 09:54:45 GMT Server: serverA Content-Type: application/json; charset=utf-8 Content-Length: 35 }

I tried your all httpclient method but I am getting the same error bad request..let me explain what I was trying.

What I have tried:

I have 2 solutions here with having different port numbers..

in 1st solution I have a method

[HttpPost("api/Product/Check1st")]  
public async Task Check([FromBody] CheckInput input)  
{  
    var result = await _productqualityChecker.CheckQualityAsync(input);  
    return new JsonResult(result);  
}  

I will keep running this solution . The url here ***api/Product/Check1st***" I will trying to call using httpclient in 2nd solution.so this url I am not giving in postman .

In my 2nd solution I have a method

[HttpPost("api/ProductQuality/Checkin2nd")]{}

this 2nd url I will give to postman and getting the input(arguments to call external api) and then it will call the httpclient as shown as below

In postman I issue a request with the following body against

http://localhost:2000/api/ProductQuality/Checkin2nd

This is the body/input/argument I am passing in the postman

{
    "productid": "2274",
    "productcorenumber": "1321",
    "value": "AE1C1F-0363-D6F-B3D-AE0029A8",
    "contacts": [
        15998,
        1012
    ],
    "ispassed": "0",
    "isok": "0",
    "isgood": "false"
}

and this will come to here(I have one method in my controller)

[HttpPost("api/ProductQuality/Checkin2nd")]  
public async Task Check([FromBody] CheckInput input)  
{  
    var result = await _Checker.Checkercall(input);  
}  

in Checkercall implementation I am calling another API(as of now calling the same for testing purposes)

public async Task Checkercall(CheckInput input)  
{  
    QualityCheckResults QualityCheckInputResult = new QualityCheckResults();  
    using (var httpClient = new HttpClient())  
    {  
        var content = new StringContent(JsonConvert.SerializeObject(input), Encoding.UTF8, "application/json");  
        using (var response = await httpClient.PostAsync("https://localhost:2001/api/ProductQuality/Check1st", content))  
        {  
            string apiResponse = await response.Content.ReadAsStringAsync();  
            QualityCheckInputResult = JsonConvert.DeserializeObject(apiResponse);  
        }  
    }  
    return QualityCheckInputResult;  
}  

This is what I am trying to do. in httpclient mtd CheckInput is the class I have created.

QualityCheckResults QualityCheckInputResult = new QualityCheckResults();

is the response class. So I can assign to this object only. May be that is the issue? I don't know

Is there anything wrong in my 2 solution call?
