是否有可能在 JSON 中发送二进制数据? 我正在在 ASP. NET MVC 中创建 REST Service 。 我想将存储在我的服务器中的 PDF 文件还给我的客户 。 我将怎么做呢? 我的数据传输介质是 JSON & amp; XML 。
看看这里:"http://www. thinkingcode.info/2015/05/how-to-send-pdf-in-json/" rel="no follow" 如何发送 pdf injson ,它列出了几种你可以考虑的方法。
最简单的方式是使用 Base64 编码将二进制数据转换为字符串。 在 C# 中, 这将意味着调用 < code> Convert. fromBase64String 。 但是, 使用 Base64 编码意味着增加 33% 的内存 。
如果您可以逃脱, 这是最不复杂的解决方案。 万一额外大小是问题, 您可以考虑把它拉上拉链 。
如果您需要 JSON 或 XML 包装文件, 您需要文本编码, 例如 Base 64 。
