第三方平台一键发布视频至抖音：基于.NET CORE

前言
既上次介绍了如何通过.net core控制台应用一键发布公众号消息后，这次来介绍一下，如何通过.net core 控制台应用一键发布视频内容至抖音，可以作为第三方分享内容至抖音的服务端方法参考，官方的示例没有提供C#的代码，并且文档也超级坑，api设计也很不友好，返回的错误码并不能真正反映问题所在，总之就是不够restful。。。这个坑我觉得比微信的文档还大。。废话不多说，开始吧 开发流程 （1）申请并成功配置应用这里我就不多介绍了，参考这一篇博客：https://blog.csdn.net/I_lost/article/details/104520655，注意将授权回调域设置好
随便说点，代码中的注释已经够清楚了。 强调一下，请求地址：https://open.douyin.com/platform/oauth/connect/ 里面配置query的部分只需要注意：回调地址即redirect_uri需要在应用的配置的授权域名下，其他没啥了。。都很简单，我这里是控制台应用，会调用本地浏览器打开抖音扫码界面 private string GetDouYinCode() { Dictionary requestParameters = new Dictionary(); //这里的client_key以及client_secret需要自己到开发者平台去开通一个应用得到 requestParameters.Add("client_key", "client_key"); requestParameters.Add("response_type", "code"); requestParameters.Add("scope", "video.create"); //redirect_uri 回调的地址，需要在开发者平台配置这个地址 requestParameters.Add("redirect_uri", "http://ccciie.com/eyuntong/(S(amksryslevropj3ib0nl0jha))/Default.aspx?id=V2.0"); string requestUrl = "https://open.douyin.com/platform/oauth/connect/"; StringBuilder stringBuilder = new StringBuilder(); stringBuilder.Append(requestUrl); if (requestParameters.Count > 0) { stringBuilder.Append("?"); foreach (var item in requestParameters) { stringBuilder.Append("&"); stringBuilder.AppendFormat("{0}={1}", item.Key, item.Value); } } string codeRequest = stringBuilder.ToString(); Console.WriteLine(codeRequest); // 控制台打开浏览器或者web 中打开新的窗口进行扫码跳转，等待用户输入code //将跳转后UTL的“code=“到”&“之间的字符复制下来，如下：6yNlI4Xu1Rc923iBNTvzQAsvK00nnie8yiTJ //https://www.a9blmo3lvm.54http.tech/?code=6yNlI4Xu1Rc923iBNTvzQAsvK00nnie8yiTJ&state= string code = OpenBrowerInputCode(codeRequest); return code; } private string OpenBrowerInputCode(string codeRequest) { // 控制台打开浏览器窗口或者web 跳转到新的页面， 地址是：codeRequest // 我这里因为是控制台应用，就用了System.Diagnostics.Process()方法，web中弄个a标签跳转到codeRequest这个地址即可， System.Diagnostics.Process.Start(@"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe", codeRequest); //用户将这个code复制下来，作为GetDouYinAcessToken(code)的传入参数 //扫码跳转后的地址示例：https://www.a9blmo3lvm.54http.tech/?code=6yNlI4Xu1Rc923iBNTvzQAsvK00nnie8yiTJ&state= string code = Console.ReadLine(); if (!string.IsNullOrWhiteSpace(code)) { return code; } return new Exception("code不能为空").ToString(); }等待用户扫码跳转确认，确认后将代码中所说的code复制到控制台中，等待执行下一步
简单说一下，这里对通过服务端方法对https://open.douyin.com/oauth/access_token/发起请求，最后将返回的open_id以及access_token取出来，用作下一步的进行视频上传的接口的参数 private void GetDouYinAcessToken(string code) { Dictionary requestParameters = new Dictionary(); requestParameters.Add("client_key", "client_key"); requestParameters.Add("client_secret", "client_secret"); requestParameters.Add("code", code); requestParameters.Add("grant_type", "authorization_code"); string requestUrl = "https://open.douyin.com/oauth/access_token/"; StringBuilder stringBuilder = new StringBuilder(); stringBuilder.Append(requestUrl); if (requestParameters.Count > 0) { stringBuilder.Append("?"); foreach (var item in requestParameters) { stringBuilder.Append("&"); stringBuilder.AppendFormat("{0}={1}", item.Key, item.Value); } } HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(stringBuilder.ToString()); httpWebRequest.ContentType = "application/json"; httpWebRequest.Method = "GET"; httpWebRequest.Timeout = 20000; HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse(); StreamReader streamReader = new StreamReader(httpWebResponse.GetResponseStream(), Encoding.UTF8); string responseContent = streamReader.ReadToEnd(); JObject jsonresult = JsonConvert.DeserializeObject(responseContent); if (jsonresult["data"]["access_token"] != null && jsonresult["data"]["open_id"] != null) { AcessToken = jsonresult["data"]["access_token"].ToString(); OpenId = jsonresult["data"]["open_id"].ToString(); } streamReader.Close(); httpWebResponse.Close(); httpWebRequest.Abort(); //return jsonresult; } （4）上传视频至服务器这里是最坑的地方。。。文档很坑，并且对于C#一点也不友好，我调试了很久，才最终上传成功。 /// /// 视频上传方法 /// /// 视频文件路径，视频大小不能超过128M，时长不能超过15分钟 /// 视频的标题 /// private JObject UploadVideoToDouYin(string path, string videoTitle) { FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read); byte[] bArr = new byte[fs.Length]; fs.Read(bArr, 0, bArr.Length); string url = string.Format("https://open.douyin.com/video/upload/?open_id={1}&access_token={0}", AcessToken, OpenId); HttpWebRequest httpWebRequest = WebRequest.Create(url) as HttpWebRequest; //httpWebRequest.AllowAutoRedirect = true; httpWebRequest.Method = "POST"; httpWebRequest.Timeout = 20000; string boundary = DateTime.Now.Ticks.ToString("X"); httpWebRequest.ContentType = "multipart/form-data;charset=utf-8;boundary=" + boundary; byte[] itemBoundaryBytes = Encoding.UTF8.GetBytes("\r\n--" + boundary + "\r\n"); byte[] endBoundaryBytes = Encoding.UTF8.GetBytes("\r\n--" + boundary + "--\r\n"); int pos = path.LastIndexOf("\\"); string fileName = path.Substring(pos + 1); //组织表单数据 StringBuilder sbHeader = new StringBuilder(); sbHeader.Append("Content-Disposition: form-data; name=\"video\"; filename=\"" + path + "\"; filelength=\"" + fs.Length + "\""); sbHeader.Append("\r\n"); //其他视频格式需要修改Content-Type:video/mp4; 格式必须是”video/“开头 sbHeader.Append("Content-Type:video/mp4;"); sbHeader.Append("\r\n\r\n"); byte[] postHeaderBytes = Encoding.UTF8.GetBytes(sbHeader.ToString()); Stream postStream = httpWebRequest.GetRequestStream(); postStream.Write(itemBoundaryBytes, 0, itemBoundaryBytes.Length); postStream.Write(postHeaderBytes, 0, postHeaderBytes.Length); postStream.Write(bArr, 0, bArr.Length); postStream.Write(endBoundaryBytes, 0, endBoundaryBytes.Length); postStream.Close(); fs.Close(); fs.Dispose(); HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse(); StreamReader streamReader = new StreamReader(httpWebResponse.GetResponseStream(), Encoding.UTF8); string responseContent = streamReader.ReadToEnd(); JObject jsonresult = JsonConvert.DeserializeObject(responseContent); streamReader.Close(); httpWebResponse.Close(); httpWebRequest.Abort(); if (jsonresult["data"]["video"]["video_id"] != null) { VideoId = jsonresult["data"]["video"]["video_id"].ToString(); Console.WriteLine(VideoId); CrateVideoForDouYin(videoTitle); } return jsonresult; } (5)发布内容到这就没啥问题了，直接参考官方文档，对内容做相应的配置即可。 private JObject CrateVideoForDouYin(string videoTitle) { //发送视频的的标题，不支持艾特某个用户 string videoContext = @"{""text"":""测试视频：人生的意义在于旅行"",""video_id"":""""}"; JObject requsetToken = JsonConvert.DeserializeObject(videoContext); requsetToken["text"] = videoTitle; requsetToken["video_id"] = VideoId; string requestUrl = string.Format("https://open.douyin.com/video/create/?open_id={0}&access_token={1}", OpenId, AcessToken); HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(requestUrl); httpWebRequest.ContentType = "application/json"; httpWebRequest.Method = "POST"; httpWebRequest.Timeout = 10000; Console.WriteLine("请求的参数为\n" + requsetToken); byte[] plcByte = Encoding.UTF8.GetBytes(requsetToken.ToString()); httpWebRequest.ContentLength = plcByte.Length; httpWebRequest.GetRequestStream().Write(plcByte, 0, plcByte.Length); HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse(); StreamReader streamReader = new StreamReader(httpWebResponse.GetResponseStream(), Encoding.UTF8); string responseContent = streamReader.ReadToEnd(); JObject responseJson = JsonConvert.DeserializeObject(responseContent); streamReader.Close(); httpWebResponse.Close(); httpWebRequest.Abort(); return responseJson; } （6）完成发布打开抖音可以看到刚才发布的视频，在集成到真的平台应用上，再写个方法将回调里的code自动抓取到，整个过程只需要用户扫码授权就可以自动发布了
水平不够，又很忙，写的代码看起来比较繁琐，大家将就看看吧。。。
