URL解码ios中的json [英] URL Decoding of json in ios

问题描述

我在php中有1个网络服务，浏览器网址为：

  http：Domain / webservice / ACTEC_WebService。 php？lastupdate = 2012-09-01 01:00:00 
  

现在当我尝试获取url在我的iphone应用程式，它采取这个网址：

  http：//Domain/webservice/ACTEC_WebService.php？lastupdate = 2012 -09-01％2001：00：00 
  

这是造成问题。

$ b

  SBJSON * json = [
 $ b 
我已使用此代码从我的网址提取数据。 SBJSON new]; 
 json.humanReadable = YES; 
 responseData = [[NSMutableData data] retain]; 
 
 NSString * service = @; 
 NSString * str 
 str = @LastUpdated; 
 
 
 NSString * requestString = [NSString stringWithFormat：@{\LastUpdated \：\％@ \}，str]; 
 
 // [[NSUserDefaults standardUserDefaults] setValue：nil forKey：@WRONGANSWER]; 
 
 NSLog（@request string：％@，requestString）; 
 NSData * requestData = [NSData dataWithBytes：[requestString UTF8String] length：[requestString length]]; 
 
 
 NSString * fileLoc = [[NSBundle mainBundle] pathForResource：@URLNameofType：@plist]; 
 NSDictionary * fileContents = [[NSDictionary alloc] initWithContentsOfFile：fileLoc]; 
 NSString * urlLoc = [fileContents objectForKey：@URL]; 
 // urlLoc = [urlLoc stringByAppendingString：service]; 
 NSLog（@URL：％@，urlLoc）; 
 
 NSMutableURLRequest * request = [[NSMutableURLRequest alloc] initWithURL：
 [NSURL URLWithString：urlLoc]]; 
 NSString * postLength = [NSString stringWithFormat：@％d，[requestData length]]; 
 [request setHTTPMethod：@POST]; 
 [request setValue：postLength forHTTPHeaderField：@Content-Length]; 
 [request setValue：@application / jsonforHTTPHeaderField：@Content-Type]; 
 [request setHTTPBody：requestData]; 
 
 NSError * respError = nil; 
 NSData * returnData = [NSURLConnection sendSynchronousRequest：request returningResponse：nil error：& respError]; 
 NSString * responseString = [[NSString alloc] initWithData：returnData encoding：NSUTF8StringEncoding]; 
 NSLog（@Resp：％@，responseString）; 
 
 if（respError）
 {
 // NSString * msg = [NSString stringWithFormat：@Connection failed！Error  - ％@％@，
 // [respError localizedDescription]，
 // [[respError userInfo] objectForKey：NSURLErrorFailingURLStringErrorKey]]; 
 UIAlertView * alertView = [[UIAlertView alloc] initWithTitle：@ACTEC
消息：@检查您的网络连接委托：self cancelButtonTitle：@OK
 otherButtonTitles：nil]; 
 [alertView show]; 
 [alertView release]; 
 
} 
 else 
 {
 ...... 
} 
  

这里，我得到null响应url正在解码...我如何使这个解决...
帮助我。
提前感谢。

解决方案

  NSString * urlLoc = [[fileContents objectForKey ：@URL] stringByAddingPercentEscapesUsingEncoding：NSUTF8StringEncoding]; 
 NSMutableData * postData = [NSMutableData data]; 
 NSMutableURLRequest * urlRequest; 
 [postData appendData：[[NSString stringWithFormat：@添加您要发送的数据] dataUsingEncoding：NSUTF8StringEncoding]]; 
 NSString * postLength = [NSString stringWithFormat：@％d，[postData length]]; 
 urlRequest = [[NSMutableURLRequest alloc] init]; 
 [urlRequest setURL：[NSURL URLWithString：urlLoc]]; 
 [urlRequest setHTTPMethod：@POST]; 
 [urlRequest setValue：postLength forHTTPHeaderField：@Content-Length]; 
 [urlRequest setValue：@application / x-www-form-urlencodedforHTTPHeaderField：@Content-Type]; 
 [urlRequest setHTTPBody：postData]; 
 
 NSString * temp = [[NSString alloc] initWithData：postData encoding：NSUTF8StringEncoding]; 
 NSLog（@\\\
\\\
url =％@ \\\
 posted data =>％@，urlLoc，temp）; 
  

检查nslog。

  NSData * response = [NSURLConnection sendSynchronousRequest：urlRequest returningResponse：nil error：nil]; 
 NSString * json_string = [[NSString alloc] initWithData：response encoding：NSUTF8StringEncoding]; 
 NSLog（@json_string>>％@，json_string）; 
  

也许这会帮助你。

I am having 1 webservice in php which is having browser url mentioned bel :

http:Domain/webservice/ACTEC_WebService.php?lastupdate=2012-09-01 01:00:00

Now when I try to fetch url in my iphone app, it is taking this url:

http://Domain/webservice/ACTEC_WebService.php?lastupdate=2012-09-01%2001:00:00

This is creating problem.

i have used this code for fetching data from my url.

     SBJSON *json = [SBJSON new];
        json.humanReadable = YES;
        responseData = [[NSMutableData data] retain];

        NSString *service = @"";
        NSString *str;
        str = @"LastUpdated";


        NSString *requestString = [NSString stringWithFormat:@"{\"LastUpdated\":\"%@\"}",str];

       // [[NSUserDefaults standardUserDefaults] setValue:nil forKey:@"WRONGANSWER"];

        NSLog(@"request string:%@",requestString);
        NSData *requestData = [NSData dataWithBytes: [requestString UTF8String] length: [requestString length]];


        NSString *fileLoc = [[NSBundle mainBundle] pathForResource:@"URLName" ofType:@"plist"];
        NSDictionary *fileContents = [[NSDictionary alloc] initWithContentsOfFile:fileLoc];
        NSString *urlLoc = [fileContents objectForKey:@"URL"];
        //urlLoc = [urlLoc stringByAppendingString:service];
        NSLog(@"URL : %@",urlLoc);

        NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: 
                                        [NSURL URLWithString:urlLoc]];  
        NSString *postLength = [NSString stringWithFormat:@"%d", [requestData length]];
        [request setHTTPMethod: @"POST"];
        [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
        [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
        [request setHTTPBody:requestData];

        NSError *respError = nil;
        NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse: nil error: &respError ];
        NSString *responseString = [[NSString alloc] initWithData:returnData encoding: NSUTF8StringEncoding];
        NSLog(@"Resp : %@",responseString);

        if (respError) 
        {
            //        NSString *msg = [NSString stringWithFormat:@"Connection failed! Error - %@ %@",
            //                         [respError localizedDescription],
            //                         [[respError userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]]; 
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"ACTEC" 
                                                                message:@"check your network connection" delegate:self cancelButtonTitle:@"OK" 
                                                      otherButtonTitles:nil];
            [alertView show];
            [alertView release];

        } 
        else
        {
......
}

here,i am getting null response as url is getting decoded...How can I make this solved... Help me out. Thanks in advance.

解决方案

NSString *urlLoc = [[fileContents objectForKey:@"URL"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 
NSMutableData *postData = [NSMutableData data];
    NSMutableURLRequest *urlRequest;        
    [postData appendData: [[NSString stringWithFormat: @"add your data which you want to send"] dataUsingEncoding: NSUTF8StringEncoding]];  
    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
    urlRequest = [[NSMutableURLRequest alloc] init];
    [urlRequest setURL:[NSURL URLWithString:urlLoc]];
    [urlRequest setHTTPMethod:@"POST"];
    [urlRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [urlRequest setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [urlRequest setHTTPBody:postData];

    NSString *temp = [[NSString alloc] initWithData:postData encoding:NSUTF8StringEncoding];
    NSLog(@"\n\nurl =%@ \n posted data =>%@",urlLoc, temp);

check nslog. that which data u send to service.

NSData *response = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:nil error:nil];
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSLog(@"json_string >> %@",json_string);

Maybe this will help you.
