C#中POST接口formdata传参模板的记录

POST接口formdata传参模板记录

var res = "";
HttpClient _httpClient = new HttpClient();
var postContent = new MultipartFormDataContent();
string boundary = string.Format("--{0}", DateTime.Now.Ticks.ToString("x"));
postContent.Headers.Add("ContentType", $"multipart/form-data, boundary={boundary}");
var requestUri = "url";

var values = new[]
{
 new KeyValuePair<string, string>("id","1")
 };

foreach (var keyValuePair in values)
{
    postContent.Add(new StringContent(keyValuePair.Value),
        String.Format("\"{0}\"", keyValuePair.Key));
}
var response = await _httpClient.PostAsync(requestUri, postContent);
//浏览器出参返回入res
if (response.IsSuccessStatusCode)
{
    res = response.Content.ReadAsStringAsync().Result;
}
//处理返回JSON数据
 var q = JsonConvert.DeserializeObject<MODEL>(res);

日后用到方便查看记录一下

C#模拟formdata提交参数

public string GetFormdata(Dictionary<string, string> dic,string ticks) {
           string Info = "";
           string Head = string.Format("----------------------------{0}", ticks);
           string Foot = string.Format("----------------------------{0}--", ticks);
           foreach (var item in dic){
               Info += string.Format("{0}\r\nContent-Disposition: form-data; name=\"{1}\"\r\n\r\n{2}\r\n", Head, item.Key, item.Value);
           }
           Info += Foot;
           return Info;
       }

string Ticks = DateTime.Now.Ticks.ToString();
                       string Paramter = GetFormdata(dic, Ticks);
                       string Html = "";
                       using (HttpHelper http = new HttpHelper()){
                           HttpItem item = new HttpItem();
                           item.URL = "http://app.farseasty.com/api/v100.smart/createSaleOrder";
                           item.Method = "post";
                           item.Header.Add("token", Token);
                           item.ContentType = string.Format("multipart/form-data; boundary=--------------------------{0}", Ticks);
                           item.PostEncoding = System.Text.Encoding.UTF8;
