I have an endpoint in a .Net Core API running in a linux container

[HttpPatch] // inside controller called Customer
public async Task<IActionResult> PatchAsync([FromBody] TestObject entity)
{
    return Ok(await _service.PatchAsync(entity));
}

The Poco

public class TestObject 
{
    [JsonProperty(PropertyName = "Code")]
    public string Code { get; set; }
    [JsonProperty(PropertyName = "Name")]
    public string Name { get; set; }
}
    

from my Blazor app I have the following code to update the entity

public async Task<bool> UpdateEntity(TestObject entity)
{
    var content = new StringContent(JsonConvert.SerializeObject(entity), Encoding.UTF8, "application/json");
    using (var httpClient = new HttpClient())
    {
        using (var response = await httpClient.PatchAsync(@"http://someserverpath:5000/api/v1/Customer", content))
        {
            string apiResponse = await response.Content.ReadAsStringAsync();
            return JsonConvert.DeserializeObject<bool>(apiResponse);
        }
    }
}

The issue I am having when I run the code locally on windows 10 it works. When I run this code inside a Linux docker container I get the following exception

Error: Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value: M. Path '', line 1, position 1.

CodePudding user response：

Try something like this:

public async Task<bool> UpdateEntity(TestObject entity)
{
    var content = new StringContent(JsonConvert.SerializeObject(entity), Encoding.UTF8, "application/json");
    using var httpClient = new HttpClient();
    using var response = await httpClient.PatchAsync(@"http://someserverpath:5000/api/v1/Customer", content);
        
    string apiResponse = await response.Content.ReadAsStringAsync();
    if (response.IsSuccessStatusCode) {
        return JsonConvert.DeserializeObject<bool>(apiResponse);
    } else {
        throw new Exception("Something went wrong when.... See inner excpetion.", new Exception(apiResponse));
    }
}

You most likely received a non successful response and need to return the exception thrown by the API. Handle it the way you normally would in your solution
