AFNeiworking 用法

1、get post请求

NSString *url1 = @"http://api.openweathermap.org/data/2.5/forecast/daily?lat=39.907501&lon=116.397232&cnt=10";//测试get请求

NSString *url2 =@"http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx/getMobileCodeInfo";//测试post请求

//创建一个请求管理类对象

AFHTTPRequestOperationManager* manager = [AFHTTPRequestOperationManager manager];

manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer. acceptableContentTypes setByAddingObject:@"text/html"];

//设置请求类型

manager.requestSerializer = [AFHTTPRequestSerializer serializer];

//设置返回类型 json AFXMLParserResponseSerializer:xml类型 AFHTTPResponseSerializer:二进制类型

//manager.responseSerializer = [AFJSONResponseSerializer serializer];

manager.responseSerializer = [AFXMLParserResponseSerializer serializer];

//get请求

[manager GET:url1parameters:nil success:^(AFHTTPRequestOperation *operation,id responseObject) {

NSLog(@"%@",responseObject);

} failure:^(AFHTTPRequestOperation *operation,NSError *error) {

NSLog(@"%@",error);

}];

//post请求，参数不显示在正文（一个网址？后面就是正文，内容就是参数），参数设置在parameters里

[manager POST:url2parameters:@{@"mobileCode":@"15910514636",@"userID":@""} success:^(AFHTTPRequestOperation *operation,id responseObject) {

NSLog(@"%@",responseObject);

} failure:^(AFHTTPRequestOperation *operation,NSError *error) {

NSLog(@"%@",error);

}];

2、上传

NSString* url = @"";

//参数

NSDictionary* paras =@{};

//获得的数据

NSDate* data =nil;

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

manager.requestSerializer = [AFHTTPRequestSerializer serializer];

manager.responseSerializer = [AFJSONResponseSerializer serializer];

manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"];

AFHTTPRequestOperation *httpoperation = [managerPOST:url parameters:paras constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {//构造数据，上传的数据

[formData appendPartWithFileData:dataname:@"upload"fileName:@"image1.jpg"mimeType:nil];

} success:^(AFHTTPRequestOperation *operation,id responseObject) {

} failure:^(AFHTTPRequestOperation *operation,NSError *error) {

}];

3、监听网络状态

//开启网络状态指示器

[[AFNetworkActivityIndicatorManager sharedManager]setEnabled:YES];

//初始化监听

AFHTTPRequestOperationManager* manager = [[AFHTTPRequestOperationManager alloc]initWithBaseURL:[NSURL URLWithString:@"http://www.baidu.com"]];

NSOperationQueue* queue = manager.operationQueue;

//监听结果回调

[manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

switch (status) {

caseAFNetworkReachabilityStatusReachableViaWiFi:

caseAFNetworkReachabilityStatusReachableViaWWAN:

[queue setSuspended:NO];//设置是否挂起该进程

NSLog(@"have net");

break;

caseAFNetworkReachabilityStatusNotReachable:

default:

[queue setSuspended:YES];

NSLog(@"no");

break;

}

}];

//开始监听

[manager.reachabilityManager startMonitoring];
