Java 有完整的 HTTP 响应代码枚举吗？

Question

我想知道某些标准 Java 类库中是否有一个枚举类型，它为所有有效的 HTTP 响应代码定义了符号常量。它应该支持与相应整数值之间的转换。

我正在调试一些使用

javax.ws.rs.core.Response.Status

的 Java 代码。它可以工作，但它只定义了大约一半的有效 HTTP 响应代码。

Answer 1

我认为标准 Java 类中没有一个完整的类；

HttpURLConnection

缺少很多代码，例如

HTTP 100/Continue

。

Apache HttpComponents 中有一个完整的列表：

org.apache.http.HttpStatus

（从 Apache Http 客户端替换了 org.apache.commons.HttpClient.HttpStatus
，已达到生命周期终点）

Answer 2

嗯，在 HttpURLConnection class

中有精确整数值的静态常量

Answer 3

Servlet API 的接口

javax.servlet.http.HttpServletResponse

具有

int

常量名称

SC_<description>

形式的所有响应代码。请参阅 http://docs.oracle.com/javaee/6/api/javax/servlet/http/HttpServletResponse.html

Answer 4

如果您使用 Spring，3.x 版本可以满足您的需求： http://static.springsource.org/spring/docs/3.0.x/api/org/springframework/http/HttpStatus.html

Answer 5

这是一个包含状态代码及其描述的枚举（在撰写本文时）对应于 HTTP 状态代码注册表。

请注意，注册表可能会更新，并且有时会使用非官方状态代码。

public enum HttpStatusCode {

    //1xx: Informational
    CONTINUE(100, "Continue"),
    SWITCHING_PROTOCOLS(101, "Switching Protocols"),
    PROCESSING(102, "Processing"),
    EARLY_HINTS(103, "Early Hints"),

    MOVED_PERMANENTLY(301, "Moved Permanently"),
    FOUND(302, "Found"),
    SEE_OTHER(303, "See Other"),
    NOT_MODIFIED(304, "Not Modified"),
    USE_PROXY(305, "Use Proxy"),
    TEMPORARY_REDIRECT(307, "Temporary Redirect"),
    PERMANENT_REDIRECT(308, "Permanent Redirect"),

    //4xx: Client Error
    BAD_REQUEST(400, "Bad Request"),

    UNPROCESSABLE_ENTITY(422, "Unprocessable Entity"),
    LOCKED(423, "Locked"),
    FAILED_DEPENDENCY(424, "Failed Dependency"),
    TOO_EARLY(425, "Too Early"),
    UPGRADE_REQUIRED(426, "Upgrade Required"),
    PRECONDITION_REQUIRED(428, "Precondition Required"),
    TOO_MANY_REQUESTS(429, "Too Many Requests"),
    REQUEST_HEADER_FIELDS_TOO_LARGE(431, "Request Header Fields Too Large"),
    UNAVAILABLE_FOR_LEGAL_REASONS(451, "Unavailable For Legal Reasons"),

    //5xx: Server Error
    INTERNAL_SERVER_ERROR(500, "Internal Server Error"),
    NOT_IMPLEMENTED(501, "Not Implemented"),
    BAD_GATEWAY(502, "Bad Gateway"),
    SERVICE_UNAVAILABLE(503, "Service Unavailable"),
    GATEWAY_TIMEOUT(504, "Gateway Timeout"),
    HTTP_VERSION_NOT_SUPPORTED(505, "HTTP Version Not Supported"),
    VARIANT_ALSO_NEGOTIATES(506, "Variant Also Negotiates"),
    INSUFFICIENT_STORAGE(507, "Insufficient Storage"),
    LOOP_DETECTED(508, "Loop Detected"),
    NOT_EXTENDED(510, "Not Extended"),
    NETWORK_AUTHENTICATION_REQUIRED(511, "Network Authentication Required");

    private final int value;
    private final String description;

    HttpStatusCode(int value, String description) {
        this.value = value;
        this.description = description;
    }

    public int getValue() {
        return value;
    }

    public String getDescription() {
        return description;
    }

    @Override
    public String toString() {
        return value + " " + description;
    }

    public static HttpStatusCode getByValue(int value) {
        for(HttpStatusCode status : values()) {
            if(status.value == value) return status;
        }
        throw new IllegalArgumentException("Invalid status code: " + value);
    }
}

Answer 6

每个人似乎都忽略了你问题的“枚举类型”部分。

虽然没有 HTTP 状态代码的规范源，但有一种简单的方法可以将您需要的任何缺失的状态常量添加到

javax.ws.rs.core.Response.Status

提供的状态常量，而无需向项目添加任何其他依赖项。

javax.ws.rs.core.Response.Status

只是

javax.ws.rs.core.Response.StatusType

接口的一种实现。您只需使用所需状态代码的定义创建自己的实现枚举即可。

Javax、Jersey 等核心库是针对接口

StatusType

编写的，而不是实现

Status

（或者它们当然应该）。由于您的新 Status 枚举实现了 StatusType

，因此它可以在任何需要使用

javax.ws.rs.core.Response.Status

 常量的地方使用。

请记住，您自己的代码也应该写入

StatusType

接口。这将使您能够使用自己的状态代码以及“标准”状态代码。

这里有一个简单实现的要点，其中包含为“信息 1xx”状态代码定义的常量：

Answer 7

如果您使用

Netty，您可以使用：

HttpResponseStatus

Answer 8

使用 javax.servlet.http.HttpServletResponse 类

示例：

javax.servlet.http.HttpServletResponse.SC_UNAUTHORIZED //401
javax.servlet.http.HttpServletResponse.SC_INTERNAL_SERVER_ERROR //500

Answer 9

1) 要获取原因

文字，如果您只有代码，可以使用：

org.apache.http.impl.EnglishReasonPhraseCatalog.INSTANCE.getReason(httpCode,null)

其中

httpCode

 是您从 HTTP 响应中获取的原因代码。

请参阅

https://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/impl/EnglishReasonPhraseCatalog.html了解详细信息

2）要获取原因

代码，如果您只有文本，可以使用BasicHttpResponse

。

请参阅此处了解详细信息：

https://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/message/BasicHttpResponse.html

Answer 10

另请查看 Restlet Status 类：

http://www.restlet.org/documentation/1.1/api/org/restlet/data/Status.html

Answer 11

http 状态代码常量的最佳提供者可能是 Jetty 的 org.eclipse.jetty.http.HttpStatus 类，因为：

我唯一要改进的地方是：将状态代码编号放在文本描述前面，以便在开始使用代码时使自动完成查找更加方便。

Answer 12

请参阅 Spring 框架中的以下枚举，它提供了所有 HTTP 响应状态代码

HttpStatus.values()

请尝试 HttpStatus.ACCEPTED.value()

Answer 15

如果您正在开发 AWS 服务，则可以使用 AWS 的 HttpStatusCode。

只是

import software.amazon.awssdk.http.HttpStatusCode;

它具有所有状态代码的枚举：

例如。

HttpStatusCode.INTERNAL_SERVER_ERROR

HttpStatusCode.OK

Answer 16

另一种选择是使用 Apache commons-httpclient 中的

HttpStatus

 类，它为您提供各种 Http 状态作为常量。
