WebAPI学习笔记（5）Asp.net调用WebAPI Post方法上传附件

1、WebAPI方法：

[HttpPost]
public HttpResponseMessage TransferData(dynamic obj)
{
            MethodReturnModel<string> returnModel = new MethodReturnModel<string>();

            try
            {
                string connectorCode = obj.connectorCode.ToString();
                string content = obj.contentJson.ToString();
                string attachments = obj.attachments.ToString();

                if (connectorCode == "" || content == "" || attachments == "")
                {
                    returnModel.Result = false;
                    returnModel.Message = "Connector code,content and attahments can be empty";
                }
                else
                {
                    List<AttachmentModel> attachmentList = MethodHelper.Json2List<AttachmentModel>(attachments);
                    if (attachmentList != null)
                    {
                        string TempFileSavePath = ConfigurationHelper.GetDownloadFileDefaultSavePath();
                        for (int i = 0; i < attachmentList.Count; i++)
                        {
                            MethodHelper.ByteToFile(attachmentList[i].bytes, HttpContext.Current.Server.MapPath(TempFileSavePath + "/" + attachmentList[i].fileName));
                        }

                        returnModel.Result = true;
                    }
                    else
                    {
                        returnModel.Result = false;
                        returnModel.Message = "No attachment";
                    }
                }
            }
            catch (Exception ex)
            {
                returnModel.Result = false;
                returnModel.Message = ex.Message;
            }

            return MethodHelper.GetHttpResponseMessage(ConvertJson.GetJson<MethodReturnModel<string>>(returnModel));
}

2、调用方式：

//测试附件
string fileName1 = "Test001.txt";
string fileName2 = "Test002.pptx";
string fileName3 = "Test003.zip";
byte[] bytes1 = FileToByte(HttpContext.Current.Server.MapPath("Temp/" + fileName1));
byte[] bytes2 = FileToByte(HttpContext.Current.Server.MapPath("Temp/" + fileName2));
byte[] bytes3 = FileToByte(HttpContext.Current.Server.MapPath("Temp/" + fileName3));

List<AttachmentModel> attachmentList = new List<AttachmentModel>();
attachmentList.Add(new AttachmentModel(fileName1, bytes1));
attachmentList.Add(new AttachmentModel(fileName2, bytes2));
attachmentList.Add(new AttachmentModel(fileName3, bytes3));

string attachmentsJson = List2Json<AttachmentModel>(attachmentList);

string Username = "xxx";
string Password = "xxx";
string Body = "{'connectorCode': '001', 'contentJson': { 'IssueKey': '009','IssueType': '111'}, 'attachments': '" + attachmentsJson + "'}";
using (HttpClient client = new HttpClient())
{
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.UTF8.GetBytes($"{Username}:{Password}")));
    HttpContent httpContent = new StringContent(Body, Encoding.UTF8);
    httpContent.Headers.Add("user-key", "xxx");
    httpContent.Headers.ContentType = new MediaTypeHeaderValue("application/json");

    Uri address = new Uri("https://localhost:44300/api/issues/TransferData");    var response = client.PostAsync(address, httpContent).Result.Content.ReadAsStringAsync().Result;//返回值
}
