DefaultResponseType

Enum DefaultResponseType 

Source
pub enum DefaultResponseType {
    Json,
    Html,
    Auto,
}
Expand description

默认响应类型策略(对齐 PHP autoResponse + 项目主策略扩展)

项目主策略为前后端分离,因此默认使用 JsonAuto 严格对齐 PHP TP 6 autoResponse() 的行为(根据 Accept 头判断)。Html 用于兜底场景 (如模板渲染、PDF/Excel 导出)。

Variants§

§

Json

项目主策略:默认返回 JSON(Content-Type: application/json; charset=utf-8)

控制器返回 Value(数组/对象)时,自动序列化为 JSON 响应。 不渲染模板,不检查 Accept 头。

§

Html

兜底场景:返回 HTML(Content-Type: text/html; charset=utf-8)

用于模板渲染、PDF/Excel 导出等非 JSON 场景。

§

Auto

对齐 PHP autoResponse:根据请求 Accept 头判断

  • Accept 含 json MIME → JSON 响应
  • Accept 不含 json MIME → HTML 响应(数组输出字面量 “Array”,对齐 PHP bug)

Implementations§

Source§

impl DefaultResponseType

Source

pub fn respond(&self, data: &Value, headers: &HeaderMap) -> Response

根据策略和请求数据生成响应

§参数
  • data:响应数据(Value::Object / Value::Array / Value::String 等)
  • headers:请求头(用于 Auto 策略判断 Accept 头)
§返回
  • Jsonrespond(data)
  • Htmlrespond_html(data.to_string())
  • Autoauto_respond(data, headers)
