ASI-HTTP-Request简介

简称ASI。

使用iOS SDK中的HTTP网络请求API比较复杂，调用很繁琐。ASI是简单易用的，它封装了CFNetwork API。使得与web服务通信变得更简单。它是使用Objective-C写的，可以在MAC OS X和iOS应用中使用

ASI地址：https://github.com/pokeb/asi-http-request

ASI第三方库配置过程

（非ARC，基于底层的CFNetwork框架；已经停止更新）

1.导入ASI的源文件

2.导入五个框架点击项目

CFNetwork.framework

SystemConfiguration.framework

MobileCoreServices.framework

libxml2.dylib

libz.dylib

选中 targers —》》bulid phases —》》

link binary with libraries 点击+号

导入需要添加的包

3.导入头文件即可使用

ASI异步get请求

1 首先创建一个url

NSURL *url =[NSURL URLWithString:@"http://www.baidu.com"];

2 创建请求

</pre><pre name="code" class="objc"><strong><span style="color:#333333;">ASIHTTPRequest *request =[ASIHTTPRequest requestWithURL:url]</span></strong>

;

3设置代理

request.delegate =self;此时需要在.h文件中导入ASIHTTPRequestDelegate.h文件

4开启异步请求

[request startAsynchronous];

以下是ASIhttp代理的方法

//获得响应头-(void)request:(ASIHTTPRequest *)request didReceiveResponseHeaders:(NSDictionary *)responseHeaders{      //获得请求状态码     // request.responseStatusCode        //遍历响应头key    for (NSString *str in [responseHeaders allKeys]) {        NSLog(@"%@",str);        }}//请求完成  -(void)requestFinished:(ASIHTTPRequest *)request{         }- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];    // Override point for customization after application launch.    self.window.backgroundColor = [UIColor whiteColor];    [self.window makeKeyAndVisible];        NSURL *url=[NSURL URLWithString:@"http://www.baidu.com"];        ASIHTTPRequest *request=[ASIHTTPRequest requestWithURL:url];            request.delegate=self;        [request startAsynchronous];    return YES;}-(void)request:(ASIHTTPRequest *)request didReceiveResponseHeaders:(NSDictionary *)responseHeaders{    NSLog(@"%d",request.responseStatusCode);            for (NSString *str in [responseHeaders allKeys]) {                NSLog(@"%@",str);            }    }-(void)request:(ASIHTTPRequest *)request didReceiveData:(NSData *)data{    }-(void)requestFinished:(ASIHTTPRequest *)request{    }

输出结果如下

ASI同步get请求

1 首先创建一个url NSURL *url =[NSURL URLWithString:@"http://www.baidu.com"];2 创建请求ASIHTTPRequest *request =[ASIHTTPRequest requestWithURL:url];3 开始请求[request startSynchronous];4获得响应数据                request.responseData;获得响应数据转化的字符串              request.responseString获得响应头内容              request.responseHeaders获得服务器响应错误           request.error- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];    // Override point for customization after application launch.    self.window.backgroundColor = [UIColor whiteColor];    [self.window makeKeyAndVisible];        NSURL *url=[NSURL URLWithString:@"http://www.baidu.com"];    ASIHTTPRequest *request=[ASIHTTPRequest requestWithURL:url];        [request startSynchronous];        //获得响应头状态码    NSLog(@"%d",request.responseStatusCode);        NSLog(@"%@",request.responseString);                return YES;}

输出结果

asi 同步POST 请求

//服务器地址    NSURL *url=[NSURL URLWithString:@"http://localhost:8080/MyFirstWeb/NewServlet"];    //asi 同步POST 请求    ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:url];    //设置请求体    [request addPostValue:@"zhangsan" forKey:@"name"];    [request addPostValue:@"123" forKey:@"password"];            request.delegate=self;    [request startSynchronous];    //服务器的响应    NSLog(@"%@",request.responseString);

注意：此时导入的是ASIFormDataRequest.h

输出结果

asi 异步POST 请求

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];    // Override point for customization after application launch.    self.window.backgroundColor = [UIColor whiteColor];    [self.window makeKeyAndVisible];        NSURL *url=[NSURL URLWithString:@"http://localhost:8080/MyFirstWeb/NewServlet"];        ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:url];        request.delegate=self;    //请求体    [request addPostValue:@"zhangsan" forKey:@"name"];        [request addPostValue:@"123" forKey:@"password"];        [request startAsynchronous];                        return YES;}//获得请求头-(void)request:(ASIHTTPRequest *)request didReceiveResponseHeaders:(NSDictionary *)responseHeaders{    NSLog(@"%d",request.responseStatusCode);    }//请求完成-(void)requestFinished:(ASIHTTPRequest *)request{    NSLog(@"%@",request.responseString);}//请求失败-(void)requestFailed:(ASIHTTPRequest *)request{    NSLog(@"%@",request.error);}
