Objective-C/CocoaHttpServer-尝试使用一个参数执行简单的GET请求 [英] Objective-C/CocoaHttpServer - Trying to do a simple GET request with one parameter

问题描述

我正在尝试使用在 https://github.com/robbiehanson/CocoaHTTPServer .我已将其添加到我的项目中，现在，如果我在浏览器中键入以下内容:192.168.3.114:45000我会收到一个名为index的html页面，带有简单的欢迎消息(此页面存储在默认项目中).还行吧.它可以正常工作.我现在需要了解的是，例如，如何执行在浏览器上键入"192.168.3.114:52000/getElement"之类的简单GET请求，并在浏览器上接收到简单的String.你能帮我个忙吗?我不知道在哪里可以配置或检查它，因为有一些类.我正在尝试研究HTTPConnection类，但由于我在Objective-C编程上是新手，所以我很困惑. 谢谢

I'm trying to use the "CocoaHTTPServer" found at https://github.com/robbiehanson/CocoaHTTPServer. I have added it to my project, and now, if i type on my browser something like this: 192.168.3.114:45000 i receive an html page called index with a simple welcome message (this page is stored inside the default project). This is ok. It works correctly. What i need to understand now, is how can i for example do a simple GET request typing on the browser something like "192.168.3.114:52000/getElement" and receive on the browser a simple String. Can you please give me help? I don't know where i can configure or check this because there are some classes. I'm trying to study the HTTPConnection class but i'm going in confusion because i'm new on the objective-c programming. Thanks

推荐答案

您必须使用自定义的HTTPConnection子类

You have to use a custom HTTPConnection subclass

@interface MyHTTPConnection : HTTPConnection
...
@end

然后您可以进行自定义URL处理

then you could do custom URL handling

@implementation MyHTTPConnection

    - (NSObject<HTTPResponse> *)httpResponseForMethod:(NSString *)method URI:(NSString *)path
    {
    HTTPLogTrace();

    if ([path isEqualToString:@"/getElement"])
    {
            NSData *data = ...
            HTTPDataResponse *response = [[HTTPDataResponse alloc] initWithData:data];
            return response;
    }

        // default behavior for all other paths  
    return [super httpResponseForMethod:method URI:path];
    }

@end

和设置HTTPServer connectionClass，以便您的服务器知道您要自己处理连接

and the set HTTPServer connectionClass so that your server knows you want to handle the connections yourself

[httpServer setConnectionClass:[MyHTTPConnection class]];
