Question

我拦截了我需要模拟的POST请求

_method = POST＆安培;数据％5BListing％5D％5Blisting_category_id％5D = 2及数据％5BListing％5D％5Blisting_subcategory_id％5D = 211

如何使用HTTPClient在C＃中发送？我发现了以下示例，但是它传递了字典。我需要构建什么来模拟上述请求，因为我不清楚

using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("http://localhost:6740");
            var content = new FormUrlEncodedContent(new[]
            {
                new KeyValuePair<string, string>("", "login")
            });
            var result = await client.PostAsync("/api/Membership/exists", content);
            string resultContent = await result.Content.ReadAsStringAsync();
            Console.WriteLine(resultContent);
        }

我认为HttpWebRequest在您的案例中更容易。

string Url = "http://localhost:6740";
HttpWebRequest request = HttpWebRequest.Create(Url) as HttpWebRequest;
string result = null;

//POST method here.
request.Method = "post";
request.ContentType = "application/x-www-form-urlencoded";

//Parameters here.
string param = "para1=data1&para2=data2";

//Maybe you need unicode or other encoding...
byte[] bs = Encoding.ASCII.GetBytes(param);

using (Stream reqStream = request.GetRequestStream())
{
    reqStream.Write(bs, 0, bs.Length);
}

using (WebResponse response = request.GetResponse())
{
    StreamReader sr = new StreamReader(response.GetResponseStream());
    result = sr.ReadToEnd();
    sr.Close();
}
