httpClient模仿Postman的form-data格式
api接口
[HttpPost(Name = "/Test/FileTest")] public JGResponse<PutFileByNameResponse> FileTest([FromForm]PutFileByNameRequest requestDto) { var capthch = GetCaptcha(); var token = GetToken(capthch.Data); requestDto.jptlAuth = token.Data.access_token; var result = RegulatoryPlatformSDK.PutFileByName(requestDto); return result; }
接口对象
public class JGRequestDto { /// <summary> /// 验证码 /// </summary> [Required] [Description("jptl-auth")] public string jptlAuth { get; set; } } public class PutFileByNameRequest : JGRequestDto { /// <summary> /// 文件 /// </summary> public IFormFile file { get; set; } /// <summary> /// 文件名 /// </summary> public string fileName { get; set; } }
第三方接口请求
public string Upload(UploadRequestDto dto) { if (dto == null) return ""; //请求 var url = SDKConfig.Host + "/third-service/upload"; List<ByteArrayContent> list = new List<ByteArrayContent>(); var interfaceCode = new ByteArrayContent(Encoding.UTF8.GetBytes(dto.interfaceCode)); interfaceCode.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("form-data") { Name = "interfaceCode" }; list.Add(interfaceCode); var param = new ByteArrayContent(Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(dto.param))); param.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("form-data") { Name = "param" }; list.Add(param); var file = new ByteArrayContent(ReadFileBytes(dto.file)); file.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("form-data") { Name = "file", FileName = dto.param["fileName"].ToString() }; list.Add(file); var content = new MultipartFormDataContent(); Action<List<ByteArrayContent>> act = (dataContents) => { foreach (var byteArrayContent in dataContents) { content.Add(byteArrayContent); } }; act(list); var response = RequestHelper.HttpPostToFormData(url, content); //, "application/x-www-form-urlencoded" var responseJson = new ResponseDto<JGResponse<PutFileByNameResponse>>(); try { responseJson = JsonConvert.DeserializeObject<ResponseDto<JGResponse<PutFileByNameResponse>>>(response); } catch (Exception) { var json = JsonConvert.DeserializeObject<ResponseDto<string>>(response); return json.Data; } if (responseJson == null) return ""; return JsonConvert.SerializeObject(responseJson.Data); }
private static Byte[] ReadFileBytes(IFormFile fileData) { byte[] data; using (var ms=new MemoryStream()) { fileData.CopyTo(ms); data = ms.ToArray(); } return data; }
post请求
/// <summary> /// 发起POST异步请求 /// </summary> /// <param name="url"></param> /// <param name="data"></param> /// <returns></returns> public static string HttpPostToFormData(string url, MultipartFormDataContent formData) { string result = null; try { HttpClient httpClient = new HttpClient(); HttpResponseMessage response = httpClient.PostAsync(url, formData).Result; if (response.IsSuccessStatusCode) { result = response.Content.ReadAsStringAsync().Result; } } catch (Exception ex) { throw ex; } return result; }
