AFNetwork3.0迁移:如何使用头和HTTP主体发布
提问于 2016-01-01 23:45:56
我正在尝试发出一个POST请求，其中包含HTTPHeader字段和一个HTTP到youtube API。
在以前的AFNetworking 2.0版本中，我通常是这样做的：
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];版本3.0的迁移文档将AFHTTPRequestOperationManager替换为AFHTTPSessionManager，但是我似乎找不到用于AFHTTPSessionManager的HTTPRequestOperationWithRequest方法。
我试过使用constructingBodyWithBlock，但它不起作用，可能是因为我做得不对。
到目前为止，这就是我所拥有的不起作用的东西：
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);
}];Stack Overflow用户

使用常用的NSObject类方法用Webservice.h和Webservice.m调用AFNetworking服务--这是我重复的答案，但它是更新的AFNetworking 3.0首先使NSObject类像Webservice.h和Webservice.m
Webservice.h
@interface Webservice : NSObject
+ (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure;
@endWebservice.m您的nsobject.m文件如下所示(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确保必须将字典键替换为“成功”和“消息”，以处理responce回调函数。
像这样使用viewcontroller.m的调用来自任何viewControllers的公共方法和来自viewControllers的任何方法。对于临时情况，我使用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
}];
}在上述方法中添加您的参数、值和webservice URL。您可以很容易地使用这个NSObjcet类。欲知更多详情，请访问AFNetworking 3.0或我用AFNetworking 2.0的旧睡衣。
