ios afnetworking 3.0 迁移：如何使用标头和 HTTP 主体进行 POST

afnetworking 3.0 Migration: how to POST with headers and HTTP Body

提问by Pranoy C

I am trying to make a POST request which has HTTPHeader Fields and a HTTP body to the youtube API.

我正在尝试向 youtube API 发出具有 HTTPHeader 字段和 HTTP 正文的 POST 请求。

Previously in version 2.0 of AFNetworking, I used to do it this way which worked:

以前在 AFNetworking 2.0 版中，我曾经这样做过，效果很好：

NSDictionary *parameters = @{@"snippet": @{@"textOriginal":self.commentToPost.text,@"parentId":self.commentReplyingTo.commentId}};

NSString *url = [NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/comments?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters
   options:0
     error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

// And finally, add it to HTTP body and job done.
[request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];



AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer.timeoutInterval=[[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request progress:nil success:^(NSURLSessionTask *task, id responseObject) {
    NSLog(@"Reply JSON: %@", responseObject);


    }
} failure:^(NSURLSessionTask *operation, NSError *error) {
    NSLog(@"Error: %@, %@, %@, %@, %@", error, operation.responseObject, operation.responseData, operation.responseString, operation.request);

}];
[operation start];

The migration docs for version 3.0 replaces AFHTTPRequestOperationManagerwith AFHTTPSessionManagerHowever I can't seem to find a HTTPRequestOperationWithRequestmethod for the AFHTTPSessionManager.

迁移文档的3.0版内容替换AFHTTPRequestOperationManager用AFHTTPSessionManager但是我似乎无法找到HTTPRequestOperationWithRequest的方法AFHTTPSessionManager。

I tried using the constructingBodyWithBlockbut it doesn't work maybe because I am not doing it correctly.

我尝试使用 ，constructingBodyWithBlock但它不起作用可能是因为我没有正确使用它。

This is what I have so far which doesn't work:

这是我到目前为止不起作用的内容：

NSDictionary *body = @{@"snippet": @{@"topLevelComment":@{@"snippet":@{@"textOriginal":self.commentToPost.text}},@"videoId":self.videoIdPostingOn}};

NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body
   options:0
     error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
serializer.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[serializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[serializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];


[manager POST:[NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]] parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {

    [formData appendPartWithHeaders:nil body:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];

}  progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    NSLog(@"Reply JSON: %@", responseObject);

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    NSLog(@"Error: %@, %@, %@, %@, %@", error, operation.responseObject, operation.responseData, operation.responseString, operation.request);

}];

Another way to call a POST method with AFNetworking 3.0 is:

使用 AFNetworking 3.0 调用 POST 方法的另一种方法是：

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

[manager POST:url parameters:parametersDictionary progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSLog(@"success!");
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"error: %@", error);
    }];

Hope it helps!

希望能帮助到你！

I was able to figure this out myself.

我能够自己弄清楚这一点。

Here's the solution.

这是解决方案。

First, you need to create the NSMutableURLRequestfrom AFJSONRequestSerializerfirst where you can set the method type to POST.

首先，您需要创建NSMutableURLRequestfrom AFJSONRequestSerializerfirst，您可以在其中将方法类型设置为 POST。

On this request, you get to setHTTPBodyafter you have set your HTTPHeaderFields. Make sure to set the body after you have set the Header fields for content-type, or else the api will give a 400 error.

根据此请求，您可以setHTTPBody在设置HTTPHeaderFields. 确保在为 content-type 设置 Header 字段后设置正文，否则 api 将给出 400 错误。

Then on the manager create a dataTaskWithRequestusing the above NSMutableURLRequest. Don't forget to resumethe dataTask at the very end or else nothing will get sent yet. Here's my solution code, hopefully someone gets to use this successfully:

然后在 manager 上创建一个dataTaskWithRequest使用上面的NSMutableURLRequest. 不要忘记最后resume的 dataTask 否则什么都不会发送。这是我的解决方案代码，希望有人成功使用它：

NSDictionary *body = @{@"snippet": @{@"topLevelComment":@{@"snippet":@{@"textOriginal":self.commentToPost.text}},@"videoId":self.videoIdPostingOn}};
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body options:0 error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];

NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:[NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]] parameters:nil error:nil];

req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
[req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[req setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];


[[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {

    if (!error) {
        NSLog(@"Reply JSON: %@", responseObject);

        if ([responseObject isKindOfClass:[NSDictionary class]]) {
              //blah blah
        }
    } else {
        NSLog(@"Error: %@, %@, %@", error, response, responseObject);
    }
}] resume];

For HTTPBodywith JSON

对于HTTPBodyJSON

[sessionManager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[sessionManager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, id parameters, NSError * __autoreleasing * error) {

    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters options:NSJSONWritingPrettyPrinted error:error];
    NSString *argString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
    return argString;
}];

[sessionManager POST:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {

    if (completion) {
        completion(responseObject, nil);
    }

} failure:^(NSURLSessionDataTask *task, NSError *error) {

    if (completion) {
        NSData *errorData = [error.userInfo objectForKey:@"com.alamofire.serialization.response.error.data"];
        NSDictionary *responseErrorObject = [NSJSONSerialization JSONObjectWithData:errorData options:NSJSONReadingAllowFragments error:nil];
        completion(responseErrorObject, error);
    }
}];

For HTTPBodywith custom String format

对于HTTPBody自定义字符串格式

[sessionManager.requestSerializer setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[sessionManager.requestSerializer setQueryStringSerializationWithBlock:^NSString *(NSURLRequest *request, id parameters, NSError * __autoreleasing * error) {

    NSString *argString = [self dictionaryToString:parameters];
    return argString;
}];

[sessionManager POST:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {

    if (completion) {
        completion(responseObject, nil);
    }

} failure:^(NSURLSessionDataTask *task, NSError *error) {

    if (completion) {
        NSData *errorData = [error.userInfo objectForKey:@"com.alamofire.serialization.response.error.data"];
        NSDictionary *responseErrorObject = [NSJSONSerialization JSONObjectWithData:errorData options:NSJSONReadingAllowFragments error:nil];
        completion(responseErrorObject, error);
    }
}];

Use common NSObjectClass method for Calling Wenservices with AFNetworking 3.0This is my Duplicate Answer but it was Updated with AFNetworking 3.0First make NSObjectClass Like Webservice.hand Webservice.m

使用通用NSObject类方法通过AFNetworking 3.0调用 Wenservices 这是我的重复答案，但它已使用 AFNetworking 3.0 更新首先使NSObject类像Webservice.h和Webservice.m

Webservice.h

网络服务.h

@interface Webservice : NSObject

+  (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure;

@end

Webservice.myour nsobject.m file is look like this.(add two functions in .m file)

Webservice.m你的 nsobject.m 文件是这样的。（在 .m 文件中添加两个函数）

#import "Webservice.h"

#define kDefaultErrorCode 12345

@implementation Webservice

+  (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure {

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [manager setResponseSerializer:[AFHTTPResponseSerializer serializer]];

    [manager POST:strURL parameters:dictParams progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        if([responseObject isKindOfClass:[NSDictionary class]]) {
            if(success) {
                success(responseObject);
            }
        }
        else {
            NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil];
            if(success) {
                success(response);
            }
        }

    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if(failure) {
            failure(error);
        }

    }];
}

@end

make sure you have to replace your dictionary key with successand messagefor handling of responce callback function

确保你必须用成功和 消息替换你的字典键来处理响应回调函数

Use like thiscall this common method from any viewcontroller.mand any methods from any viewControllers. for temporary i am using viewDidLoadfor calling This WS.

像这样使用从任何viewcontroller.m调用这个通用方法和来自 any 的 任何方法viewControllers。暂时我用它viewDidLoad来调用这个 WS。

 - (void)viewDidLoad {
        [super viewDidLoad];

        NSDictionary *dictParam = @{@"parameter1":@"value1",@"parameter1":@"value2"};

        [Webservice requestPostUrl:@"add your webservice URL here" parameters:dictParam success:^(NSDictionary *responce) {
            //Success
            NSLog(@"responce:%@",responce);
            //do code here
        } failure:^(NSError *error) {
            //error
        }];
    }

add your Parameter, values and webservice URL in above method. you can easily use this NSObjcetClass. for more details please visit AFNetworking 3.0or my old answear with AFNetworking 2.0.

在上述方法中添加您的参数、值和网络服务 URL。你可以很容易地使用这个NSObjcet类。有关更多详细信息，请访问AFNetworking 3.0或我对 AFNetworking 2.0 的旧回答。
