AFNetworking POST method call

问题

I am new to AFNetworking. How can i execute the success and failure blocks of the following

NSMutableDictionary *rus = [[NSMutableDictionary alloc] init];
[rus setValue:@"1211" forKey:@"id"];
[rus setValue:@"33" forKey:@"man"];
    [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:@"http://mysite.co/service.php" rus];

How to show the success or failure after executing the above code fragment.

回答1:

requestWithMethod does not actually complete the call, it just returns you an NSMutableURLRequest. You need to take that request and make an AFHTTPRequestOperation. You can set a success/failure block on this object and then run the start method.

NSMutableDictionary *rus = [[NSMutableDictionary alloc] init];
[rus setValue:@"1211" forKey:@"id"];
[rus setValue:@"33" forKey:@"man"];
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] requestWithMethod:@"POST" URLString:@"http://mysite.co/service.php" parameters:rus];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    // Code for success
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    //Code for failure
}];
[operation start];

All that being said, are you using an outdated version of AFNetworking? The method you're referencing is deprecated.

- (NSMutableURLRequest *)requestWithMethod:(NSString *)method
                             URLString:(NSString *)URLString
                            parameters:(id)parameters
                                 error:(NSError *__autoreleasing *)error

Above is the correct method to use. You should pass in an error object.

Finally, an even easier way to accomplish what you're doing with AFNetworking 2.0 is below:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:@"http://mysite.co/service.php" parameters:rus success:^(AFHTTPRequestOperation *operation, id responseObject) {
    // Code for success
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    // Code for failure
}];

Try this code:

NSMutableDictionary *rus = [[NSMutableDictionary alloc] init];
[rus setValue:@"1211" forKey:@"id"];
[rus setValue:@"33" forKey:@"man"];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:@"http://mysite.co/service.php" parameters:rus success:^(AFHTTPRequestOperation *operation, id responseObject) {

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

}];

回答3:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager POST:@"http://mysite.co/service.php" parameters:rus success:^(AFHTTPRequestOperation *operation, id responseObject) {
    // Code for success
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    // Code for failure
}];
