高性能API可观测性升级Windows/Linux桌面执行蓝图

GoogleAPIClientLibraries.CloudFunctions.V2 SixLabors.ImageSharp 步骤： 创建 Cloud Functions 项目：在 Google Cloud 控制台中创建新项目或选择现有项目。 安装依赖项：打开 NuGet 包管理器并安装以下包： ``` Install-Package GoogleAPIClientLibraries.CloudFunctions.V2 Install-Package SixLabors.ImageSharp ``` 创建 Cloud Function：在项目文件夹中创建新 C类文件（例如 `VideoRegistration.cs`）并添加以下代码： ```csharp using System; using System.Drawing; using System.IO; using System.Linq; using System.Net; using System.Net.Http; using System.Threading; using System.Threading.Tasks; using SixLabors.ImageSharp; using Google.Cloud.Functions.Framework; using Google.Events.Protobuf.Cloud.Functions.V2; using Microsoft.AspNetCore.Http; namespace YourNamespace; public class VideoRegistration : ICloudEventFunction { public async Task HandleAsync(HttpContext context, FunctionEventData data, CancellationToken cancellationToken) { // 从请求中获取视频和元数据 var videoFile = context.Request.Form.Files["video"]; var contentType = context.Request.Form["contentType"]; var name = context.Request.Form["name"]; // 检查视频格式 if (videoFile.ContentType != "video/mp4") { throw new HttpRequestException("Invalid video format. Only MP4 is supported."); } // 解析视频元数据 var videoMetadata = videoFile.FileName.Split('_'); var videoId = videoMetadata[0]; var timestamp = videoMetadata[1]; // 创建帧快照 using var image = Image.Load(videoFile.OpenReadStream()); var thumbnail = image.Clone(ctx => ctx.Resize(256, 256)); var thumbnailStream = new MemoryStream(); thumbnail.S影音eAsPng(thumbnailStream); // 创建用户对象 var user = new User { Id = videoId, Name = name, Timestamp = timestamp, ThumbnailData = thumbnailStream.ToArray() }; // 将用户保存到数据库（省略，因数据库操作而异） // 返回成功响应 HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.Created); await context.Response.WriteAsync(response.ToString(), cancellationToken); } // 用户类（仅供示例） public class User { public string Id { get; set; } public string Name { get; set; } public string Timestamp { get; set; } public byte[] ThumbnailData { get; set; } } } ``` 4. 部署 Cloud Function：从项目文件夹中运行以下命令： ``` func deploy video-registration ``` 5. 在 HTTP 请求中发送视频：使用包含视频文件、元数据和名称作为表单数据的 HTTP POST 请求来调用 Cloud Function。 示例请求： ``` POST /video-registration HTTP/1 Content-Type: multipart/form-data; boundary=boundary --boundary Content-Disposition: form-data; name="video"; filename="user-123_2023010mp4" Content-Type: video/mp4 [Video data] --boundary Content-Disposition: form-data; name="contentType" video/mp4 --boundary Content-Disposition: form-data; name="name" John Doe --boundary-- ``` 注意： 确保将 `contentType` 和 `name` 字段替换为实际值。 将 `user-123` 替换为实际用户 ID。 将 `20230101` 替换为视频的时间戳。The Big Oxmox advised her not to do so, because there were thousands of bad Commas, wild Question Marks and devious Semikoli, but the Little Blind Text didn’t listen.
