iOS网络开发-AFNetworking请求asp.net WebService

看到园子有位朋友需要使用AFN框架请求 WebService，所以就整理了一下，demo下载链接在底部

编写WebService可以看这篇博客 http://www.cnblogs.com/linmingjun/p/4606451.html

//使用AFN请问无参方法

//使用AFN无参
-(void)AfnDemo
{

    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://115.231.54.166:9090/JobRecordAPP.asmx/QueryWeather"] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20.0f];
    AFHTTPRequestOperation *operation =[[AFHTTPRequestOperation alloc] initWithRequest:request];
    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        //返回字符串
        NSString *html = operation.responseString;
        NSLog(@"html----%@",html);
        //将返回字符串头去掉：<?xml version=\"1.0\" encoding=\"utf-8\"?>
        NSString *str =@"<?xml version=\"1.0\" encoding=\"utf-8\"?>";
        NSString *strhtml =[html stringByReplacingOccurrencesOfString:str withString:@""];
        //将返回字符串头去掉
        strhtml = [strhtml stringByReplacingOccurrencesOfString:@"<string xmlns=\"http://tempuri.org/\">" withString:@""];
        //将返回的字符串尾去掉
        strhtml = [strhtml stringByReplacingOccurrencesOfString:@"</string>" withString:@""];
        //去掉结尾空格
        NSCharacterSet *whiteSpace = [NSCharacterSet whitespaceAndNewlineCharacterSet];
        strhtml= [[NSString alloc]initWithString:[strhtml stringByTrimmingCharactersInSet:whiteSpace]];
        NSLog(@"无参----%@",strhtml);

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        [self initFailure];
    }];
    [operation start];
}

//使用AFN有参
-(void)AfnDemo2:(NSString *)catObj
{

    NSString *url = @"http://115.231.54.166:9090/JobRecordAPP.asmx/BrowseStatistics?";
    //设置参数
    NSString *k_initUrl3 =[url stringByAppendingFormat:@"LoginID=%@",catObj];
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:k_initUrl3] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20.0f];
    AFHTTPRequestOperation *operation =[[AFHTTPRequestOperation alloc] initWithRequest:request];
    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSString *html = operation.responseString;
        //将返回字符串头去掉：<?xml version=\"1.0\" encoding=\"utf-8\"?>
        NSString *str =@"<?xml version=\"1.0\" encoding=\"utf-8\"?>";
        NSString *strhtml =[html stringByReplacingOccurrencesOfString:str withString:@""];
        //将返回字符串头去掉
        strhtml = [strhtml stringByReplacingOccurrencesOfString:@"<string xmlns=\"http://tempuri.org/\">" withString:@""];
        //将返回的字符串尾去掉
        strhtml = [strhtml stringByReplacingOccurrencesOfString:@"</string>" withString:@""];
        //去掉结尾空格
        NSCharacterSet *whiteSpace = [NSCharacterSet whitespaceAndNewlineCharacterSet];
        strhtml= [[NSString alloc]initWithString:[strhtml stringByTrimmingCharactersInSet:whiteSpace]];
        NSLog(@"有参----%@",strhtml);

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        [self initFailure];
    }];
    [operation start];
}

在使用.Net Web服务编写WebService,如上图我们可以看到返回的数据，前后数据多出了

<?xml version=\"1.0\" encoding=\"utf-8\"?>

<string xmlns=\"http://tempuri.org/\">

</string>
所以在得到json格式的数据的时候，先把前后多余的数据给替换了设置为空。
完整案例数据解析过程 NSString->NSData->NSarray

//从
-(void)initSetting
{
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://115.231.54.166:9090/JobRecordAPP.asmx/QueryWeather"] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:20.0f];
    AFHTTPRequestOperation *operation =[[AFHTTPRequestOperation alloc] initWithRequest:request];
    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSString *html = operation.responseString;
        //将返回字符串头去掉：<?xml version=\"1.0\" encoding=\"utf-8\"?>
        NSString *str =@"<?xml version=\"1.0\" encoding=\"utf-8\"?>";
        NSString *strhtml =[html stringByReplacingOccurrencesOfString:str withString:@""];
        //将返回字符串头去掉
        strhtml = [strhtml stringByReplacingOccurrencesOfString:@"<string xmlns=\"http://tempuri.org/\">" withString:@""];
        //将返回的字符串尾去掉
        strhtml = [strhtml stringByReplacingOccurrencesOfString:@"</string>" withString:@""];
        //去掉结尾空格
        NSCharacterSet *whiteSpace = [NSCharacterSet whitespaceAndNewlineCharacterSet];
        strhtml= [[NSString alloc]initWithString:[strhtml stringByTrimmingCharactersInSet:whiteSpace]];

       NSData *data= [strhtml dataUsingEncoding:NSUTF8StringEncoding];

        [[ProblemPaperKindObject share] videoWithDict:[data JSONValue]];

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        [self initFailure];
    }];
    [operation start];

}
