如何使用AFNetworking 2设置HTTP请求？ [英] How to set HTTP request using AFNetworking 2?

问题描述

我需要发送普通的HTTP请求（GET），答案将以text / html格式显示。
如何使用AFNetworkin 2发送此响应？

I need to send ordinary HTTP request (GET) and answer will in text/html. How can I send this response using AFNetworkin 2 ?

现在我正在尝试使用

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://example.com"]];
[self HTTPRequestOperationWithRequest:request
                              success:^(AFHTTPRequestOperation *operation, id responseObject) {
                                  NSLog(@"JSON: %@", responseObject);
                              } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                                  NSLog(@"Error: %@", error);
                              }];

很沮丧-它什么也没做。调试时，也未触发成功或失败子句。

And was frustrates - it do nothing. When debugging, nor success nor fail clause have been triggered.

我也尝试使用GET：parameters：success：failure：方法，但作为响应，我看到此错误：

Also I tried to use GET:parameters:success:failure: method, but in response I see this error:

错误：错误域= AFNetworkingErrorDomain代码= -1016请求
失败：不可接受的内容类型：text / html

Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/html"

请任何人都可以向我解释错误的地方以及正确的发送请求的方式（如果我将以text / html的形式获得回复） ）？

Please, anybody can explain me what are wrong and what is the correct way to send request (if I will get response as text/html)?

推荐答案

您在评论，针对使用 AFHTTPRequestOperationManager 的建议：

You said in your comment, in response to the suggestion to use the AFHTTPRequestOperationManager:

GET我收到上面写的错误：错误：错误Domain = AFNetworkingErrorDomain代码= -1016请求失败：内容类型不可接受：text / html

When I used GET I got this error as I wrote above: Error: Error Domain=AFNetworkingErrorDomain Code=-1016 "Request failed: unacceptable content-type: text/html"

您可以使用 AFHTTPResponseSerializer 进行补救：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
[manager GET:@"https://example.com" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    // do whatever you'd like here; for example, if you want to convert 
    // it to a string and log it, you might do something like:

    NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"%@", string);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

您还可以使用 AFHTTPRequestOperation ：

NSOperationQueue *networkQueue = [[NSOperationQueue alloc] init];
networkQueue.maxConcurrentOperationCount = 5;

NSURL *url = [NSURL URLWithString:@"https://example.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    // do whatever you'd like here; for example, if you want to convert 
    // it to a string and log it, you might do something like:

    NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
    NSLog(@"%@", string);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"%s: AFHTTPRequestOperation error: %@", __FUNCTION__, error);
}];
[networkQueue addOperation:operation];

但是理想情况下，建议编写返回JSON（或XML）的服务器代码，因为这很多应用程序更易于使用和解析。

Ideally, though, it's advisable to write server code that returns JSON (or XML), as that's much easier for an app to consume and parse.
