Question

我试图将我的代码从NSUrlConnection更新为NSUrlSession。该应用程序运行正常，没有错误，但令牌永远不会上传到MySQL数据库......我真的不知道？我应该实施代表还是我做了一些非常错误的基本内容？： - ）

NSString *deviceToken = [[NSUserDefaults standardUserDefaults] objectForKey:@"deviceToken"];
//Information is only uploaded to SQLite database if 'deviceToken' is not null
if ([deviceToken length] > 0) {
    NSURL *url = [NSURL URLWithString:@"http://sampleUrl.com/do.php"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    NSString *varString = [NSString stringWithFormat:@"deviceToken=%@", deviceToken];

    NSData *requestData = [varString dataUsingEncoding:NSUTF8StringEncoding];

    [request setHTTPMethod:@"POST"];
    [request setValue:@"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8" forHTTPHeaderField:@"Accept"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [request setValue:[NSString stringWithFormat:@"%lu", (unsigned long)[requestData length]] forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody: requestData];


    NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];

    NSURLSession *session = [NSURLSession sessionWithConfiguration:config];

    /*NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:request fromData:requestData completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
        //Handle
    }];*/

    //NSURLSessionUploadTask *uploadTask2 = [session uploadTaskWithStreamedRequest:request];
    NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
        //Handle
    }];
    [dataTask resume];

有什么想法吗？感谢致敬，汤姆

我解决了这个问题：

NSString *deviceToken = [[NSUserDefaults standardUserDefaults] objectForKey:@"deviceToken"];

//Information is only uploaded to SQLite database if 'deviceToken' is not null
if ([deviceToken length] > 0) {
    // Create URL and URLRequest
    NSURL *url = [NSURL URLWithString:@"http://url.com/something.php"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

    //Create the body
    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    NSString *varString = [NSString stringWithFormat:@"deviceToken=%@", deviceToken"]];

    // Create POST parameters and add it to HTTPBody
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody: [varString dataUsingEncoding:NSUTF8StringEncoding]];

    // Set up a simple and asynchronous NSURLSession to send data to the php
    // Set up the session configuration and header data
    NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];

    [config setRequestCachePolicy:NSURLRequestUseProtocolCachePolicy];
    [config setHTTPAdditionalHeaders:@{
                                       @"Accept" : @"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",

                                       @"Content-Type" : @"application/x-www-form-urlencoded",

                                       @"Content-Length" : [NSString stringWithFormat:@"%lu", (unsigned long)[[varString dataUsingEncoding:NSUTF8StringEncoding] length]]
                                       }];

    // Create the session and the task
    NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
    NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
        if (error)
            NSLog(@"Connection failed! Error - %@ %@",
                  [error localizedDescription],
                  [[error userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]);

        if (response)
        {
            NSLog(@"response description: %@", response.description);
            [prefs setBool:YES forKey:@"tokenSent"];
        }

        if (data)
            NSLog(@"data description: %@", data.description);
    }];
    // Start the task
    [task resume];
}
