ios - JSON POST 在 Poster/HTTP Client(Mac) 中工作正常，但在 XCode 中的 iOS 应用程序中工作不正常

Question

我正在尝试将 JSON 内容发布到 Web 服务。它在 POSTER(firefox 插件)和 HTTP Client (Mac) 中运行良好。但尝试从 XCode(iOS 应用程序)进行 POST 时会抛出 500-内部服务器错误。有人可以帮我解决这个问题吗？

请求详细信息是:-

HTTP 方法:POST

内容类型:application/json

HTTP 正文:

Answer 1

我现在可以成功发送请求了。我以错误的方式构建了 HTTP 请求，这对我来说很糟糕。

解决方案:对“Content-Type”、“Content-Length”等 http header 使用 setValue:forHTTPHeaderField: 而NOT setValue:forKey: p>

我想只要 key 是唯一的，我们是否使用它们中的任何一个都没关系。 但我错了。
