php - 如何向PHP服务器发送数据？

Question

我在执行此代码以将数据发送到我的 PHP 服务器时遇到问题 有人能帮我吗。 这是让我头疼的代码，这是我的 Outlets/文本字段。

@property (weak, nonatomic) IBOutlet UITextField *parentsNameTextField;
@property (weak, nonatomic) IBOutlet UITextField *professionTextField;
@property (weak, nonatomic) IBOutlet UITextField *addressTextField;
@property (weak, nonatomic) IBOutlet UITextField *contactTextField;
@property (weak, nonatomic) IBOutlet UITextField *emailAddressTextField;
@property (weak, nonatomic) IBOutlet UITextField *osTypeTextField;

这是操作按钮

- (IBAction)registerButtonTapped:(id)sender {


 NSString *post = [NSString stringWithFormat:@"&parentNameTextField=%@&professionTextField=%@",@"parentNameTextField",@"professionTextField"];



NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%lu", (unsigned long)[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];




[request setURL:[NSURL URLWithString:@"http://a7c8a2a.ngrok.com/usermanagement_dummy/user/register"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

NSURLConnection *conn = [[NSURLConnection alloc]initWithRequest:request delegate:self];
if (conn)
{
    NSLog(@"Connection Success");

}
else
{
    NSLog(@"Connection could not be made");

}

我m trying my best to continue but i don不知道该怎么做。 任何帮助将不胜感激。

NSMutableDictionary *get = [[NSMutableDictionary alloc]init];
[get setObject:@"parentNameTextField" forKey:@"parentNameTextField"]; 
[get setObject:@"parentNameTextField" forKey:@"professionTextField"]; 


if([NSJSONSerialization isValidJSONObject:get]){


//convert object to data
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:get options:kNilOptions error:nil];


NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"http://a7c8a2a.ngrok.com/usermanagement_dummy/user/register"]];


[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setHTTPBody:jsonData];


NSURLSessionConfiguration *config=[NSURLSessionConfiguration defaultSessionConfiguration];

NSURLSession *session=[NSURLSession sessionWithConfiguration:config];

NSURLSessionDataTask *task=[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {

    if(response){
        NSString *resp = [[NSString alloc] initWithBytes:[data bytes] length:[data length] encoding:NSUTF8StringEncoding];
        NSLog(@"Echo %@",resp);


    }

    else{
        NSLog(@"Timeout");

    }



}];
[task resume];


}

制作键值对字典。然后创建 q request 和 NSURLSessionDataTask 以POST 你的参数。在完成处理程序代码中你可以得到 response 你也可以在 dataTaskWithRequest completion handler 中添加 error 处理 试试下面的代码。这对你有用
