Question

我尝试使用HttpClient向api发送数据，但参数I＆m; m发送保持接收为0.

我在这里做错了什么？这是我第一次使用HttpClient，所以我很可能混合了一些东西或者犯了一些菜鸟错误。

路径是正确的，我可以从Postman获得结果。

代码I使用的是这个;

static async Task GetActivityList()
{
    string uri = "/api/ExtraNet/GetActivityList";

    HttpClient client = new HttpClient();

    int SalesPersonId = 553;
    string token = my token value is here;

    client.BaseAddress = new Uri("http://localhost:16513/");
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(
        new MediaTypeWithQualityHeaderValue("application/json"));
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

    var postData = "{\"SalesPersonId=\":\""+SalesPersonId+"\"}";
    var stringContent = new StringContent( "{\"SalesPersonId=\":\"" + SalesPersonId + "\"}", Encoding.UTF8, "application/json") ;
    var content = new StringContent(postData, Encoding.UTF8, "application/json");

    var response = await client.PostAsync("http://localhost:16513/api/ExtraNet/GetActivityList", stringContent);
    var result = await response.Content.ReadAsStringAsync();
    Console.WriteLine(result);
}

我设法以这种方式发送参数

string uri = "/api/ExtraNet/GetActivityList";

            HttpClient client = new HttpClient();

            int SalesPersonId = 553;
            string token = "";

            client.BaseAddress = new Uri("http://localhost:16513/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(
                new MediaTypeWithQualityHeaderValue("application/json"));
            client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

            var stringContent = new FormUrlEncodedContent(new[] {
                new KeyValuePair<string,string>("SalesPersonId","553")
            });

            var response = await client.PostAsync(uri, stringContent);
            var result = await response.Content.ReadAsStringAsync();
            Console.WriteLine(result);

将参数发送为FormUrlEncodedContent就可以了。

HttpClient发送参数null
