目前我在 iPhone 应用程序中工作，使用 JSON 发送请求并获取响应以读取它。
请求(示例 url):
http://www.Genifer.com/index.php?q=api/username-available&username=stephen
我指的是来自浏览器 (Firefox) 的响应:
{"status":true,"result":true}
我在 xcode 中尝试过:
NSString *urlString = [NSString stringWithFormat:@" http://www.Genifer.com/index.php?"];
NSString *parameter = [NSString stringWithFormat:@"q=api/username-available&username=stephen"];
NSData *parameterData = [parameter dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
[theRequest addValue: @"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody:parameterData];
NSURLConnection *connection = [[NSURLConnection alloc]
initWithRequest:theRequest delegate:self];
if( connection )
{
mutableData = [[NSMutableData alloc] init];
}
else
{
}
-(void) connection:(NSURLConnection *) connection didReceiveResponse:(NSURLResponse *)response
{
[mutableData setLength:0];
NSLog(@"mutableData:%@",mutableData);
}
-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[mutableData appendData:data];
NSLog(@"mutableData:%@",mutableData);
}
-(void) connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
[mutableData release];
[connection release];
return;
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSString *jsonStr = [[NSString alloc] initWithData:mutableData encoding:NSUTF8StringEncoding];
NSLog(@"JSonSTr : %@", jsonStr);
}
响应来了:
JSonSTr : <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" dir="ltr">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
我在 Firefox 浏览器中引用请求得到类似 {"status":true,"result":true} 的响应。 但我试图在 xcode 中集成相同的请求，但响应不同，如何解决这个问题？ 请帮助我
提前致谢
最佳答案
你能检查一下吗
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSDictionary *jsonDict = [jsonString JSONValue];
通过做这样的事情来检查字典中弹出的值
NSDictionary *question = [jsonDict objectForKey:@"status"];
