使用 Asp.net core 2.1 的 HTTP 客户端补丁方法，错误请求

Question

使用HttpClient 执行 PATCH 方法请求时出现错误请求错误

var patchDoc = new JsonPatchDocument<ClientOrganisationRequestArgs>();
patchDoc.Replace(e => e.Name, clientOrganisationRequestArgs.Name);
var serializedDoc = JsonConvert.SerializeObject(patchDoc);
var requestContent = new StringContent(serializedDoc, Encoding.UTF8, "application/json-patch+json");

var httpResponseMessage = await _httpClient.PatchAsync(
    $"api/orgs/{clientOrganisationRequestArgs.ClientRefId}", requestContent);

型号

public class ClientOrganisationRequestArgs
{
    public int ClientRefId { get; set; }        
    public string Name { get; set; }
    public string DefaultTimezone => "AUSTRALIA/SYDNEY";
    public string CustomStylePath { get; set; }
}

请求错误时获得 400

Postman 还显示 500 内部服务器错误，正文为原始内容

授权和接受标头

_httpClient.DefaultRequestHeaders.Add(
                HeaderNames.Accept, "application/vnd.yellowfin.api-v1.3+json");
_authorizationHeader =
                $"{_authorizationHeader}, token={accessToken.SecurityToken}";
            
            _httpClient.DefaultRequestHeaders.TryAddWithoutValidation(
                HeaderNames.Authorization, _authorizationHeader);

Answer 1

您有 application/json-patch+json 作为内容类型

//...

var requestContent = new StringContent(serializedDoc, Encoding.UTF8, "application/json-patch+json");

//...

但根据显示的文档，它需要简单的 application/json 内容类型标题

var requestContent = new StringContent(serializedDoc, Encoding.UTF8, "application/json");

同样基于所示文档中的示例，有效负载是一个纯 JSON 文档，看起来并不真正遵循 JSON Patch 文档格式。这可能会导致 API 无法识别请求内容。

我建议序列化有效负载以匹配给定的示例

string serializedDoc = JsonConvert.SerializeObject(clientOrganisationRequestArgs);

StringContent requestContent = new StringContent(serializedDoc, Encoding.UTF8, "application/json");

string url = $"api/orgs/{clientOrganisationRequestArgs.ClientRefId}";

var httpResponseMessage = await _httpClient.PatchAsync(url, requestContent);

假设

public class ClientOrganisationRequestArgs {
    [JsonProperty("clientRefId")]
    public int ClientRefId { get; set; }
    [JsonProperty("name")]
    public string Name { get; set; }
    [JsonProperty("defaultTimezone")]
    public string DefaultTimezone => "AUSTRALIA/SYDNEY";
    [JsonProperty("customStylePath")]
    public string CustomStylePath { get; set; }
}
