iphone - AFNetworking 2.0 向 GET 请求添加 header

Question

我刚刚开始使用 AFNetworking 2.0，我想知道如何将 header 放入 HTTP Get 请求中。文档设置了这样的 GET:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = @{@"foo": @"bar"};
[manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];

但由于我们不处理 NSURLRequests 我不确定如何设置 HTTP header 。

任何帮助将不胜感激。
问候，

Answer 1

这是一个使用 AFNetworking 2.0 的示例

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"calvinAndHobbesRock" forHTTPHeaderField:@"X-I do what I want"];

[manager GET:@"http://localhost:3000" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

关键是以下两行:

manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager.requestSerializer setValue:@"calvinAndHobbessRock" forHTTPHeaderField:@"X-I-do-what-I-want"];
