httpclient 調用.net core webapi接口上傳文件的實現

直接上代碼

        /// <summary>
        /// 向webapi發送請求執行導入操作
        /// </summary>
        /// <param name="token">身份驗證token</param>
        /// <param name="reauestUrl">api請求完整路徑</param>
        /// <param name="bytes">文件byte[]</param>
        /// <param name="fileName">文件名稱</param>
        /// <returns></returns>
        private string PostImport(string token, string reauestUrl, byte[] bytes,string fileName)
        {
            HttpClient httpClient = new HttpClient();
            //httpClient.BaseAddress = new Uri(reauestUrl);
            //httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", token);
            httpClient.DefaultRequestHeaders.Add("Authorization", token);
            ByteArrayContent fileContent = new ByteArrayContent(bytes);
            fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data") { Name = "file", FileName = fileName };
            MultipartFormDataContent content = new MultipartFormDataContent();
            content.Add(fileContent);
            var result = httpClient.PostAsync(reauestUrl, content);
            return result.Result.Content.ReadAsStringAsync().Result;
        }
