安装XAMPP和Coda,创建本地服务器>>http://localhost/index.html
左为XAMPP(Apache服务器,MySQL数据库,PHP) 右为Coda
在Coda中创建登录界面(Get 和 Post)和Get,Post接受请求界面:
1 <!-- login.php --> 2 3 <html > 4 <head > 5 <meta charset="utf-8"/> 6 <title >My Web</title> 7 </head> 8 9 <!---------------------------------------> 10 11 <body > 12 <!-- POST 请求 --> 13 <form method="post" action="http://localhost/post.php"> 14 15 <!-- GET 请求 --> 16 <!-- <form method="get" action="http://localhost/get.php"> 17 --> 18 <p align="center">用户名:<input type="text" name="username"> </p> 19 <br/> 20 <p align="center">密 码:<input type="text" name="password"> </p> 21 <br/> 22 <p align="center"><input type="submit" value="登录"/></p> 23 </form> 24 </body> 25 </html>
GET请求 -> http://localhost/get.php?username=zhangwei&password=123456
1 <?php 2 header("Content-type:text/html; charset=utf-8"); 3 4 // 获取form表单值 5 $username = $_GET[‘username‘]; 6 $password = $_GET[‘password‘]; 7 8 // 判断form表单中key 9 if(isset($_GET[‘username‘]) && isset($_GET[‘password‘])){ 10 11 // 判断username和password 12 if($username == "zhangwei" && $password == "123456"){ 13 14 $result = array("success" => 1, "code" => 101, "data" => array("username" => $username, "password" => $password)); 15 16 }else{ 17 $result = array("success" => 0, "code" => 103, "data" => null); 18 } 19 20 }else{ 21 $result = array("success" => 0, "code" => 100, "data" => null); 22 } 23 // 将错误信息(数组)转换成json类型,返回前端 24 echo(json_encode($result)); 25 ?>
POST请求 -> http://localhost/post.php
1 <?php 2 header("Content-type:text/html; charset=utf-8"); 3 4 // 获取form表单值 5 $username = $_POST[‘username‘]; 6 $password = $_POST[‘password‘]; 7 8 // 判断form表单中key 9 if(isset($_POST[‘username‘]) && isset($_POST[‘password‘])){ 10 11 // 判断username和password 12 if($username == "zhangwei" && $password == "123456"){ 13 14 $result = array("success" => 1, "code" => 101, "data" => array("username" => $username, "password" => $password)); 15 16 }else{ 17 $result = array("success" => 0, "code" => 103, "data" => null); 18 } 19 20 }else{ 21 $result = array("success" => 0, "code" => 100, "data" => null); 22 } 23 // 将错误信息(数组)转换成json类型,返回前端 24 echo(json_encode($result)); 25 ?>
在Xcode中进行解析:
1 NSURL *url = [NSURL URLWithString:@"http://127.0.0.1/post.php?username=zhangwei&password=123456"]; 2 /* 3 NSURL *url = [NSURL URLWithString:@"http://127.0.0.1/post.php"]; 4 */ 5 6 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10]; 7 8 request.HTTPMethod = /* @"POST" */ @"GET"; 9 10 /* 11 request.HTTPBody = [@"username=zhangwei&password=123456" dataUsingEncoding:NSUTF8StringEncoding]; 12 */ 13 // iOS 9 解析方法 14 NSURLSession *session = [NSURLSession sharedSession]; 15 16 NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) { 17 NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil]; 18 NSLog(@"%@", dict); 19 }]; 20 // 启动Task 21 [task resume]; 22 23 打印结果: 24 2016-04-20 21:50:40.227 GET[13393:312923] { 25 code = 101; 26 data = { 27 password = 123456; 28 username = zhangwei; 29 }; 30 success = 1; 31 }
