Reasons to Stay Alive by Matt Haig

本文引用Emily Dickinson的名言探讨了生命的宝贵与甜美,强调了个人成长与自我发现的重要性。作者通过阅读来旅行时间,寻找内在宝藏,认为书籍是心灵的导航图。同时,文章反思了现代社会对焦虑的制造,提倡活在当下,珍惜每一刻。

As Emily Dickinson, eternally great poet and occasionally anxious agoraphobe, said: ‘That it will never come again is what makes life so sweet.’


Minds move. Personalities shift. To quote myself, from The Humans: ‘Your mind is a galaxy. More dark than light. But the light makes it worthwhile. Which is to say, don’t kill yourself. Even when the darkness is total. Always know that life is not still. Time is space. You are moving through that galaxy. Wait for the stars.’


Every time I read a great book I felt I was reading a kind of map, a treasure map, and the treasure I was being directed to was in actual fact myself. But each map was incomplete, and I would only locate the treasure if I read all the books, and so the process of finding my best self was an endless quest. And books themselves seemed to me to reflect this idea. Which is why the plot of every book ever can be boiled down to ‘someone is looking for something’.


THE WORLD IS increasingly designed to depress us. Happiness isn’t very good for the economy. If we were happy with what we had, why would we need more? How do you sell an anti-ageing moisturiser? You make someone worry about ageing. How do you get people to vote for a political party? You make them worry about immigration. How do you get them to buy insurance? By making them worry about everything. How do you get them to have plastic surgery? By highlighting their physical flaws. How do you get them to watch a TV show? By making them worry about missing out. How do you get them to buy a new smartphone? By making them feel like they are being left behind.


Live in the present. Here is meditation master Amit Ray: ‘If you want to conquer the anxiety of life, live in the moment. Live in the breath.’


I hate depression. I am scared of it. Terrified, in fact. But at the same time, it has made me who I am. And if – for me – it is the price of feeling life, it’s a price always worth paying. I am satisfied just to be.


How to travel in time: read.


Remember that there is nothing weird about you. You are just a human, and everything you do and feel is a natural thing, because we are natural animals. You are nature. You are a hominid ape. You are in the world and the world is in you. Everything connects.


Just as none of us are 100% physically healthy no one is 100% mentally healthy. We are all on a scale.

在使用 C# 请求文件流时遇到 `Failed to fetch` 错误,通常表明在尝试获取远程或本地文件流时出现了问题。以下是可能导致此错误的一些常见原因及其对应的解决方案: ### 1. 网络连接问题 - **原因**:如果文件位于远程服务器上,网络中断、连接超时或服务器不可达都可能导致请求失败。 - **解决方案**:确保网络连接稳定,并验证服务器是否正常运行。可以使用 `Ping` 或 `HttpClient` 检查远程服务器的可达性。 ### 2. 文件路径错误或不存在 - **原因**:提供的文件路径可能不正确、拼写错误,或者文件已被删除或移动。 - **解决方案**:检查文件路径是否正确。对于远程文件,确保 URL 是有效的。对于本地文件,使用 `File.Exists` 方法验证文件是否存在。 ```csharp if (File.Exists("path/to/file")) { using (FileStream fs = File.OpenRead("path/to/file")) { // 读取文件流 } } else { Console.WriteLine("文件不存在"); } ``` ### 3. 权限不足 - **原因**:应用程序可能没有访问文件或远程资源的权限。 - **解决方案**:检查文件或远程资源的访问权限。对于远程资源,确保提供了正确的身份验证凭据,例如使用 `HttpClient` 时设置 `HttpClientHandler`。 ```csharp var handler = new HttpClientHandler { Credentials = new NetworkCredential("username", "password") }; using (var client = new HttpClient(handler)) { var response = await client.GetAsync("https://example.com/file"); if (response.IsSuccessStatusCode) { var stream = await response.Content.ReadAsStreamAsync(); // 处理流 } } ``` ### 4. 资源暂时不可用 - **原因**:远程服务可能因资源限制或维护而暂时不可用。 - **解决方案**:实现重试逻辑,使用 **Retry 模式** 自动重试失败的请求。可以使用 `Polly` 库来简化重试逻辑的实现。 ```csharp var retryPolicy = Policy .Handle<HttpRequestException>() .WaitAndRetryAsync(3, retryAttempt => TimeSpan.FromSeconds(Math.Pow(2, retryAttempt))); await retryPolicy.ExecuteAsync(async () => { using (var client = new HttpClient()) .[^1] { var response = await client.GetAsync("https://example.com/file"); response.EnsureSuccessStatusCode(); var stream = await response.Content.ReadAsStreamAsync(); // 处理流 } }); ``` ### 5. 文件被其他进程占用 - **原因**:本地文件可能被另一个进程锁定,导致无法读取。 - **解决方案**:确保文件未被其他程序占用。可以尝试使用 `FileStream` 的 `FileShare` 参数来允许其他进程同时访问文件。 ```csharp using (FileStream fs = new FileStream("path/to/file", FileMode.Open, FileAccess.Read, FileShare.ReadWrite)) { // 读取文件流 } ``` ### 6. 异步操作未正确处理 - **原因**:未正确等待异步操作完成,导致流未完全获取。 - **解决方案**:确保使用 `await` 正确处理异步方法,并捕获可能的异常。 ```csharp try { using (var client = new HttpClient()) { var stream = await client.GetStreamAsync("https://example.com/file"); // 处理流 } } catch (Exception ex) { Console.WriteLine($"请求失败: {ex.Message}"); } ``` ### 7. 服务器端配置问题 - **原因**:服务器可能配置了 CORS 策略、防火墙规则或 SSL 证书问题,导致请求被拒绝。 - **解决方案**:检查服务器日志,确认请求是否到达。对于 SSL 问题,可以使用 `HttpClientHandler.ServerCertificateCustomValidationCallback` 忽略证书错误(仅用于测试环境)。 ```csharp var handler = new HttpClientHandler { ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => true }; using (var client = new HttpClient(handler)) { var stream = await client.GetStreamAsync("https://example.com/file"); // 处理流 } ``` ---
