java - 想要使用 RESTful Web 服务通过 JSON 响应其他语言字体(印地语)

Question

我有一个代码，可以根据其 url 搜索数据库并生成相关结果。当数据库中的数据是英文时它工作得很好但是当我用我的语言(印地语)替换它时它开始产生垃圾编码。从我的方法生成的 JSON 响应完美地生成了所需的数据，但浏览器没有以正确的方式显示它(印地语)....

请帮我找出问题所在..

Answer 1

问题出在您的数据的字符编码上。您正在使用一种称为 UTF-8 的编码。但是您的浏览器认为您使用的是 ISO-8859，因为当您不告诉浏览器您想要什么时，这是 HTML 的标准。在 java 中，您可以使用 HttpServletResposne 对象来配置此信息。只需调用:

response.setCharacterEncoding("UTF-8");

然后浏览器将正确解释数据。这通常是通过过滤器或项目的另一个中心点来完成的，因为今天大多数项目都希望使用 UTF-8 进行完整的通信，以避免遇到你现在面临的问题
