양식 제출, 첨부 파일(사진 밤 들기) 업로드, 다운로드 코드:
첫 번째 단계: 실체 클래스를 가져오고 반사를 통해 키 값이 맞습니다.
People people = new People();
people 할당...
class GetEntityKeyValue
{
public static Dictionary getProperties(T t) where T : class // ， T Class 。
{
Dictionary dic = new Dictionary();
Type type = t.GetType();// Type
// Type.GetProperties PropertyInfo[], foreach
foreach (PropertyInfo pi in type.GetProperties())
{
object value1 = pi.GetValue(t, null);// pi.GetValue
string name = pi.Name;// ,
//
dic.Add(name,value1);
}
return dic;
}
} Dictionarydic= GetEntityKeyValue.getProperties(people );
2단계: 첨부 파일 업로드 및 양식 데이터 제출
HttpClient httpClient = new HttpClient();
string url = "******************";
string filename = "******";//
using (var form = new MultipartFormDataContent())
{ string fileName = Path.GetFileNameWithoutExtension(imagePath);
var imageContent = new ByteArrayContent(ImageHelper.ImageToBytes(finishImg)); imageContent.Headers.Add("Content-Type", "multipart/form-data"); imageContent.Headers.Add("Content-Disposition", "form-data; name=\"sketch\"; filename=\"" + fileName + "\""); form.Add(imageContent, "sketch", fileName); foreach (var keyValuePair indic) { if (keyValuePair.Value != null) { form.Add(new StringContent(keyValuePair.Value.ToString()), String.Format("\"{0}\"", keyValuePair.Key)); } } var response = httpClient.PostAsync(url, form).Result; if (response.StatusCode == System.Net.HttpStatusCode.OK) { // 200 } else { // } }3단계: 이미지 다운로드
HttpClient httpClient = new HttpClient();
HttpResponseMessage responseImg = httpClient.GetAsync(new Uri(url)).Result;
Stream streamIMg = responseImg.Content.ReadAsStreamAsync().Result;
byte[] bytes = new byte[streamIMg.Length];
streamIMg.Read(bytes, 0, bytes.Length);
//
streamIMg.Seek(0, SeekOrigin.Begin);
//
// ImageHelper ，bytes Image
