正如比尔·伯吉斯在评论中提到的那样,这个问题与version 1.3
的{{1}}有关。这里的新人可能已经过时了。
我对iPhone开发很陌生,我正在使用AFNetworking作为我的服务库。
我正在查询的API是一个RESTful,我需要发出POST请求。为此,我尝试使用以下代码:
AFNetworking
此代码存在两个主要问题:
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:@"my_username", @"username", @"my_password", @"password", nil];
NSURL *url = [NSURL URLWithString:@"http://localhost:8080/login"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
NSLog(@"Pass Response = %@", JSON);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
NSLog(@"Failed Response : %@", JSON);
}];
[operation start];
似乎发出了AFJSONRequestOperation
个请求,而不是GET
个请求。我也试过这段代码:
POST
有没有更好的方法来制作我想要的东西来完成它?
感谢您的帮助!

您可以覆盖与AFNetworking
一起使用的请求的默认行为,以便作为POST进行处理。
NSURLRequest *request = [client requestWithMethod:@"POST" path:path parameters:nil];
这假设您已覆盖默认的AFNetworking
设置以使用自定义客户端。如果你不是,我会建议你这样做。只需创建一个自定义类来为您处理网络客户端。
<强> MyAPIClient.h 强>
#import <Foundation/Foundation.h>
#import "AFHTTPClient.h"
@interface MyAPIClient : AFHTTPClient
+(MyAPIClient *)sharedClient;
@end
<强> MyAPIClient.m 强>
@implementation MyAPIClient
+(MyAPIClient *)sharedClient {
static MyAPIClient *_sharedClient = nil;
static dispatch_once_t oncePredicate;
dispatch_once(&oncePredicate, ^{
_sharedClient = [[self alloc] initWithBaseURL:[NSURL URLWithString:webAddress]];
});
return _sharedClient;
}
-(id)initWithBaseURL:(NSURL *)url {
self = [super initWithBaseURL:url];
if (!self) {
return nil;
}
[self registerHTTPOperationClass:[AFJSONRequestOperation class]];
[self setDefaultHeader:@"Accept" value:@"application/json"];
self.parameterEncoding = AFJSONParameterEncoding;
return self;
}
然后你应该能够在没有问题的情况下在操作队列上启动网络调用。
MyAPIClient *client = [MyAPIClient sharedClient];
[[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
[[AFNetworkActivityIndicatorManager sharedManager] incrementActivityCount];
NSString *path = [NSString stringWithFormat:@"myapipath/?value=%@", value];
NSURLRequest *request = [client requestWithMethod:@"POST" path:path parameters:nil];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
// code for successful return goes here
[[AFNetworkActivityIndicatorManager sharedManager] decrementActivityCount];
// do something with return data
}failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
// code for failed request goes here
[[AFNetworkActivityIndicatorManager sharedManager] decrementActivityCount];
// do something on failure
}];
[operation start];
