AFNetworking 发布请求 [英] AFNetworking Post Request

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:@"https://example.com/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:@"https://example.com/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:@"https://example.com/"];
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);
}];
