AFNetworking 发布请求

本文介绍了AFNetworking 发布请求的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我是 obj-c 的新手，并且一直在我的一些项目中使用 asihttp.在 asihttp 中执行 post 请求时，它就是这样完成的.

I'm a newbie in obj-c and have been using asihttp for some of my projects. When doing a post request in asihttp its done this way.

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url]; [request setPostValue:height forKey:@"user[height]"]; [request setPostValue:weight forKey:@"user[weight]"]; [request setDelegate:self]; [request startAsynchronous];

AFNetworking 将如何使用代码示例执行此操作?我已经在 AFNetworking 中使用了 get Json getrequest，但是这个 post 请求给我带来了一些问题.提前感谢您的帮助.

How would go about doing this is AFNetworking with a code example ? I already got the get Json getrequest working in AFNetworking but this post request is giving me some problems. Thanks for help in advance.

推荐答案

首先值得补充的是(因为这个答案在我最初写它的 6 年后仍然很受欢迎......)你应该考虑的第一件事是你是否应该甚至使用 AFNetworking.NSURLSession 是在 iOS 7 中添加的，这意味着在许多情况下您不需要使用 AFNetworking - 少一个第三方库总是一件好事.

It's first worth adding (as this answer is still popular 6 years after I initially wrote it...) that the first thing you should consider is whether you should even use AFNetworking. NSURLSession was added in iOS 7 and means you don't need to use AFNetworking in many cases - and one less third party library is always a good thing.

对于 AFNetworking 3.0:

For AFNetworking 3.0:

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; NSDictionary *params = @{@"user[height]": height, @"user[weight]": weight}; [manager POST:@"example/myobject" parameters:params progress:nil success:^(NSURLSessionTask *task, id responseObject) { NSLog(@"JSON: %@", responseObject); } failure:^(NSURLSessionTask *operation, NSError *error) { NSLog(@"Error: %@", error); }];

对于 AFNetworking 2.0(并且还使用新的 NSDictionary 语法):

For AFNetworking 2.0 (and also using the new NSDictionary syntax):

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; NSDictionary *params = @{@"user[height]": height, @"user[weight]": weight}; [manager POST:@"example/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"JSON: %@", responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); }];

如果您在使用 AFNetworking 1.0 时遇到困难，您需要这样做:

If you are stuck using AFNetworking 1.0, you need to do it this way:

NSURL *url = [NSURL URLWithString:@"example/"]; AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url]; NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: height, @"user[height]", weight, @"user[weight]", nil]; [httpClient postPath:@"/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; NSLog(@"Request Successful, response '%@'", responseStr); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"[HTTPClient Error]: %@", error.localizedDescription); }];
