在我的应用程序中，我正在尝试向服务器发出 POST 请求以将产品添加到购物车。我的代码如下：
#import "CreateCarriage.h"
#import "NSData+Base64.h"
@implementation CreateCarriage{
NSMutableData *datas;
NSString *prodID;
}
- (void)createCarriageWithProductID:(NSString *)productID {
self.qty = @"1";
prodID = productID;
[self sendRequestToURL:self.buyUrl withMethod:@"POST"];
}
- (id)sendRequestToURL:(NSString *)url withMethod:(NSString *)method {
NSURL *finalUrl;
if ([method isEqualToString:@"POST"]) {
finalUrl = [NSURL URLWithString:url];
} else {
NSLog(@"Metodo non previsto");
}
NSString *post = [NSString stringWithFormat:@"form_key=%@&product=%@&related_product=&qty=%@", self.formKey, prodID, self.qty];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:finalUrl];
[request setHTTPMethod:method];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Current-Type"];
[request setHTTPBody:postData];
NSLog(@"%@", request);
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
if (connection) {
[connection start];
}
return connection;
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
datas = [[NSMutableData alloc]init];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
NSLog(@"%@", [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]);
[datas appendData:data];
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSLog(@"Oggetto aggiunto al carrello");
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(@"%@", error);
}
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
NSString *username = @"user";
NSString *password = @"password";
NSURLCredential *credential = [NSURLCredential credentialWithUser:username
password:password
persistence:NSURLCredentialPersistenceForSession];
[[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
}
@end
当我运行应用程序并尝试将此产品添加到购物车时，它会显示以下 html：

您可以在其中看到我没有在我的购物车中添加任何东西......这段代码有什么问题？
更新：
我尝试使用 Chrome 来查看浏览器所做的 POST/GET 请求，我将在此处发布响应：

我想我应该使用它的部分，Form Data它向我展示了这个请求：form_key=7CUKq8086ReKwIjs&product=2&related_product=&qty=1如果你看一下我的 iOS 代码，你会发现我试图做同样的事情。
