建设公司网站靠谱吗,企业宣传推广,新公司简介模板范文,wordpress添加百度自动推送今天在公司开始着手做了一个项目,要和网络接号对接的,有以下一点点小心得,上来分享一下: 首先说ios的网络请求,方式有很多种,我把它分了两种,一种是外框架型,一种是内框架;前都是应用了官方API以外的框架,后者则是相对; -(void)testRequest{ NSLog("test request...&qu…

今天在公司开始着手做了一个项目,要和网络接号对接的,有以下一点点小心得,上来分享一下:

首先说ios的网络请求,方式有很多种,我把它分了两种,一种是外框架型,一种是内框架;前都是应用了官方API以外的框架,后者则是相对;

-(void)testRequest
{
    NSLog(@"test request...");
    NSString *postUrl = @"url";
    NSMutableDictionary *dlist = [[NSMutableDictionary alloc] init];


    [dlist setObject:@"value" forKey:@"key"];
    ....

    NSString *jsonStrPost = [self sendRequestTo:[NSURL URLWithString:postUrl] usingVerb:@"POST" withParameters:dlist];
    NSLog(@"do post: jsonStrPost = %@", jsonStrPost);
}

上面用的就是有点像json的做法,ios的,呵!

下面再说另一种做法:

//quest
/**
 * url:请求地址
 * verb:请求方式
 * parameters:请求参数
*/
-(NSString *)sendRequestTo:(NSURL *)url usingVerb:(NSString *)verb withParameters:(NSDictionary *)parameters{
    NSString *jsonStr = nil;
    NSData *body = nil;
    NSMutableString *params = nil;
    NSString *contentType = @"text/html; charset=utf-8";
    NSURL *finalURL = url;
if(nil != parameters){
params = [[NSMutableString alloc] init];
for(id key in parameters){
            NSString *encodedkey = [key stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

            CFStringRef value = (__bridge CFStringRef)[[parameters objectForKey:key] copy];
            CFStringRef encodedValue = CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, value,NULL,(CFStringRef)@";/?:@&=+$", kCFStringEncodingUTF8);
            [params appendFormat:@"%@=%@&", encodedkey, encodedValue];
            CFRelease(value);
            CFRelease(encodedValue);
        }
        [params deleteCharactersInRange:NSMakeRange([params length] - 1, 1)];
    }
//
    if([verb isEqualToString:@"POST"]){
        contentType = @"application/x-www-form-urlencoded; charset=utf-8";
        body = [params dataUsingEncoding:NSUTF8StringEncoding];
    }else{
if(nil != parameters){
            NSString *urlWithParams = [[url absoluteString] stringByAppendingFormat:@"?%@", params];
            finalURL = [NSURL URLWithString:urlWithParams];
        }
    }
    NSMutableDictionary *headers = [[NSMutableDictionary alloc] init];
    [headers setValue:contentType forKey:@"Content-Type"];
    [headers setValue:@"text/html" forKey:@"Accept"];
    [headers setValue:@"no-cache" forKey:@"Cache-Control"];
    [headers setValue:@"no-cache" forKey:@"Pragma"];
    [headers setValue:@"close" forKey:@"Connection"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:finalURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
    [request setHTTPMethod:verb];
    [request setAllHTTPHeaderFields:headers];
if(nil != parameters){
        [request setHTTPBody:body];
    }
params = nil;
//
    NSURLResponse *response;
    NSError *error = nil;
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
if(error){
        NSLog(@"something is wrong: %@", [error description]);
    }else{
if(responseData){
            jsonStr = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
        }
    }
return  jsonStr;
}

NSString *jsonStrPost = [self sendRequestTo:[NSURL URLWithString:postUrl] usingVerb:@"POST" withParameters:dlist];

下面是第三种了~有什么疑问可以留言,偶会常看博客的了!

NSString *requestString = [NSString stringWithFormat:@"url"];
// 数据内容转换为UTF8编码，第二个参数为数据长度
//    NSData *requestData = [NSData dataWithBytes:[requestString UTF8String] length:[requestString length]];
// 请求的URL地址
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:requestString]];
    NSLog(@"%@\n",requestString);
// 设置请求方式
//[request setHTTPMethod:@"get"];
// 设置请求内容
//[request setHTTPBody:requestData];
// 设置请求头声明
    [request setValue:@"text/xml" forHTTPHeaderField:@"Content-type"];    
// 执行请求
    NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];


// 输出返回数据
    NSString *returnString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    NSLog(@"%@", returnString);

上面三种方法都有POST和GET两种方式的其实他们也是差不多的,不过写法不一样而已

第四种用的是一个开源的框架,要导的包有点多,要注意了哦~

ASIFormDataRequest,或ASIHTTPRequest,这两个东西不错的哦,我这次的项目就是用这个东西做的

ASIFormDataRequest:

这个要引入的包有:(明天补上)

ASIFormDataRequest* req=[[ASIFormDataRequest alloc] init];
    NSString* s_url=@"url";
    req = [[ASIFormDataRequest alloc] initWithURL:[NSURL URLWithString:s_url]];
    [req setRequestMethod:@"POST"];//@"GET""POST"
    [req setDelegate:self];

    [req setPostValue:value forKey:key];
  .....


    [req startAsynchronous];

结果返回时会自动调用以下方法

- (void)requestFinished:(ASIHTTPRequest *)request
{
int i = 0;
//乱码的处理,呵
    NSString * temp = [[[NSString alloc]initWithData:[request responseData] encoding:NSUTF8StringEncoding]autorelease];
    NSArray * ttemp = [temp componentsSeparatedByString:@","];


}
