如何使用HttpClient将带有JSON的DELETE发送到RESTAPI

我必须使用HttpClient类向具有JSON内容的REST API服务发送删除命令,并且无法使其正常工作.

API调用:

DELETE /xxx/current
{
 "authentication_token": ""
}

因为我无法在下面的语句中添加任何内容:

HttpResponseMessage respOnse= client.DeleteAsync(requestUri).Result;

我知道如何使用RestSharp来完成这项工作:

var request = new RestRequest {
    Resource = "/xxx/current",
    Method = Method.DELETE,
    RequestFormat = DataFormat.Json
};

var jsOnPayload= JsonConvert.SerializeObject(cancelDto, Formatting.Indented);

request.Parameters.Clear();
request.AddHeader("Content-type", "application/json");
request.AddHeader ("Accept", "application/json");
request.AddParameter ("application/json", jsonPayload, ParameterType.RequestBody);

var respOnse= await client.ExecuteTaskAsync (request);

但我没有RestSharp就完成了.

虽然回答这个问题可能会迟到,但我遇到了类似的问题,以下代码对我有用.

HttpRequestMessage request = new HttpRequestMessage
{
    COntent= new StringContent("[YOUR JSON GOES HERE]", Encoding.UTF8, "application/json"),
    Method = HttpMethod.Delete,
    RequestUri = new Uri("[YOUR URL GOES HERE]")
};
await httpClient.SendAsync(request);

您可以使用以下扩展方法:

public static class HttpClientExtensions
{
    public static Task DeleteAsJsonAsync(this HttpClient httpClient, string requestUri, T data)
        => httpClient.SendAsync(new HttpRequestMessage(HttpMethod.Delete, requestUri) { COntent= Serialize(data) });

    public static Task DeleteAsJsonAsync(this HttpClient httpClient, string requestUri, T data, CancellationToken cancellationToken)
        => httpClient.SendAsync(new HttpRequestMessage(HttpMethod.Delete, requestUri) { COntent= Serialize(data) }, cancellationToken);

    public static Task DeleteAsJsonAsync(this HttpClient httpClient, Uri requestUri, T data)
        => httpClient.SendAsync(new HttpRequestMessage(HttpMethod.Delete, requestUri) { COntent= Serialize(data) });

    public static Task DeleteAsJsonAsync(this HttpClient httpClient, Uri requestUri, T data, CancellationToken cancellationToken)
        => httpClient.SendAsync(new HttpRequestMessage(HttpMethod.Delete, requestUri) { COntent= Serialize(data) }, cancellationToken);

    private static HttpContent Serialize(object data) => new StringContent(JsonConvert.SerializeObject(data), Encoding.UTF8, "application/json");
}
