Question

是否有人知道在iOS SDK中是否定义了HTTP状态代码as specified here？或者我是否应该在常量文件中手动重新定义它们？

Answer 1

嗯，它们的定义是

[NSHTTPURLResponse localizedStringForStatusCode:(NSInteger)statusCode]

可以返回给定状态代码的字符串。那是你在找什么？

Answer 2

我做了

grep -r '404' *

在

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/System/Lib‌rary/Frameworks/

然后空手而归，所以答案肯定是“不”。

Answer 3

有一个完整的Obj-C库，其中包含迄今为止定义的所有代码： https://github.com/rafiki270/HTTP-Status-Codes-for-Objective-C

<强>更新：新的Swift版本在这里： https://github.com/manGoweb/StatusCodes

Answer 4

http状态代码可以由服务器响应定义。当有连接时，您可以使用NSURLResponse读出statusCode。这些4 **响应可以在您的服务器内部定义。

Answer 5

我也找不到我期望存在的头文件，所以我必须写一个我自己的头文件。

在GitHub的nv-ios-http-status项目中包含HTTPStatusCodes.h，基于HTTP状态代码的调度可以写成如下所示。

#import "HTTPStatusCodes.h"

......

- (void)connection:(NSURLConnection *)connection
  didReceiveResponse:(NSURLResponse *)response
{
    NSHTTPURLResponse *res = (NSHTTPURLResponse *)response;

    switch ([res statusCode])
    {
        // 200 OK
        case kHTTPStatusCodeOK:
            ......;
    }

    ......
}

我希望HTTPStatusCodes.h可以节省您和其他开发人员的时间。

还有一个Swift吊坠可以重复使用它：

Answer 7

恐怕您将不得不手动定义它们。我不熟悉Objective-C，以下是我的快速定义：

Swift 4中基于https://httpstatuses.com/的HTTP状态枚举

with app.test_client() as client:
    json.loads(client.get("the/url").get_data().decode("utf-8"))
    # ...

HttpStatusEnum.strings

是否在iOS SDK中的任何位置定义了HTTP状态代码？
