AFNetworking的用法

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];
//注意：此行不加也可以   
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:url1 parameters: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:url2 parameters:@{@"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 = 
[manager POST: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];
