NSURLSession network request, nsurlsession request

I personally feel that it is difficult to find simple network requests on the Internet. Maybe it's just me that I'm not familiar with it. All of them have the following sections. Although they are all code, they all have comments.

// 1/obtain the file access path NSString * path = @ "http://1.studyios.sinaapp.com/getAllClass.php"; // 2. encapsulate url nsurl * url = [NSURL URLWithString: path]; // 3. create request command NSURLRequest * request = [NSURLRequest requestWithURL: url]; // 4. create a session object and implement NSURLSession * session = [NSURLSession sharedSession] using the single-profit method; // 5. the task that executes the session obtains the data Object NSURLSessionDataTask * datatask = [session dataTaskWithRequest: request completionHandler: ^ (NSData * _ Nullable data, NSURLResponse * _ Nullable response, NSError * _ Nullable error) {// 7. json NSArray * arrJson = [NSJSONSerialization JSONObjectWithData: data options: NSJSONReadingMutableLeaves error: & error]; NSLog (@ "% @", arrJson); // NSLog (@ "% @", data);}]; // 6. real task execution [datatask resume];
