问题描述
我的 iOS
项目中有以下代码,我想转换为使用 NSURLSession
而不是 NSURLConnection的
。我正在查询 REST API
,它使用基于令牌的 HTTP身份验证
方案,但我找不到如何的示例执行它。
I have the following code in my iOS
project and I want to convert to use NSURLSession
instead of NSURLConnection
. I am querying a REST API
which uses a token-based HTTP Authentication
scheme but I cannot find an example of how to do it.
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
NSString *username = [[NSUserDefaults standardUserDefaults] stringForKey:@"Username"];
NSString *token = //GET THE TOKEN FROM THE KEYCHAIN
NSString *authValue = [NSString stringWithFormat:@"Token %@",token];
[request setValue:authValue forHTTPHeaderField:@"Authorization"];
if ([NSURLConnection canHandleRequest:request]){
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
[NSURLConnection sendAsynchronousRequest:request queue:self.fetchQueue
completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
if (!connectionError) {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
if (httpResponse.statusCode == 200){
NSDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers|NSJSONReadingAllowFragments error:nil];
//Process the data
}
}
}];
}
推荐答案
您可以使用NSURLSession重写它如下所示
You can rewrite it using NSURLSession as follows
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
NSString *token ; //GET THE TOKEN FROM THE KEYCHAIN
NSString *authValue = [NSString stringWithFormat:@"Token %@",token];
//Configure your session with common header fields like authorization etc
NSURLSessionConfiguration *sessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
sessionConfiguration.HTTPAdditionalHeaders = @{@"Authorization": authValue};
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfiguration];
NSString *url;
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]];
NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
if (!error) {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
if (httpResponse.statusCode == 200){
NSDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers|NSJSONReadingAllowFragments error:nil];
//Process the data
}
}
}];
[task resume];
