JavaHTTP响应结果类HTTPResult

HTTP 响应结果类 HTTPResult，用于表示 HTTP 请求后的响应结果。它具有属性响应码 code、消息 message 和数据 data

• 响应结果
  • success()：成功响应，返回状态码为 200，并且提示语为“成功”
  • badRequest()：错误请求响应，返回状态码为 400，并且提示语为“错误请求”
  • unauthorized()：未授权响应，返回状态码为 401，并且提示语为“未授权”
  • forbidden()：禁止访问响应，返回状态码为 403，并且提示语为“禁止访问”
  • notFound()：未找到响应，返回状态码为 404，并且提示语为“未找到”
  • internalServerError()：内部服务器错误响应，返回状态码为 500，并且中文提示语为“内部服务器错误”
  • serviceUnavailable()：服务不可用响应，返回状态码为 503，并且中文提示语为“服务不可用”
• 获取提示语
  • getMessageEn()：根据状态码返回对应的英文提示语
  • getMessageZh()：根据状态码返回对应的中文提示语
• 转化 JSON 格式
  • toJSONObject()：将当前 HTTP 响应结果对象转换成 JSON 对象并返回
  • toJSONString()：将当前 HTTP 响应结果对象转换成 JSON 字符串并返回

其中转化 JSON 格式涉及的函数基于阿里巴巴的 Fastjson 包，需先在 Maven 的 pom.xml 加上依赖

<dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.47</version>
</dependency>

后在 Java 中引入包

import com.alibaba.fastjson.*
