ios-程序中模拟GET和POST请求登录

我们在程序中模拟发出GET请求进行登录，如果账号或密码中存在汉字或者空格我们就要进行处理

 NSString *name = @"哈";    NSString *pwd = @"123";       NSString *strUrl = [NSString stringWithFormat:@"http://127.0.0.1/php/login.php?username=%@&password=%@",name,pwd];    //对汉字或者空格做百分号转义，URLQuery就是对?之后进行的百分号转义操作。    strUrl = [strUrl stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];            //当地址中出现空格或者汉字 url返回nil,所以我们需要在上面给它做一次百分号转义操作    NSURL *url = [NSURL URLWithString:strUrl];             NSURLRequest *request = [NSURLRequest requestWithURL:url];[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse * _Nullable    response, NSData * _Nullable data, NSError * _Nullable connectionError) {        if (connectionError) {            NSLog(@"连接错误 %@",connectionError);            return;        }                //        NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;        if (httpResponse.statusCode == 200 || httpResponse.statusCode == 304) {            //解析数据            NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL];            NSLog(@"%@",dic);                    }else{            NSLog(@"服务器内部错误");        }    }];}

以post的形式发送请求

 NSString *strUrl = @"http://127.0.0.1/php/login.php";        NSURL *url = [NSURL URLWithString:strUrl];   //如果需要改变请求的方式就要把request的类变成是mutableRequest   NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];    //发送post请求    request.HTTPMethod = @"post";    //设置请求体    NSString *body = @"username=123&password=abc";    //把字符串转换成NSData对象，以UTF-8编码的形式    request.HTTPBody = [body dataUsingEncoding:NSUTF8StringEncoding];        [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) {        if (connectionError) {            NSLog(@"连接错误 %@",connectionError);            return;        }                //        NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;        if (httpResponse.statusCode == 200 || httpResponse.statusCode == 304) {            //解析数据            NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL];            NSLog(@"%@",dic);        }else{            NSLog(@"服务器内部错误");        }    }];
