从目标 C 获取 coldfusion 中的 POST 值

Question

I am trying to post a string to a URL in iphone which will be retrieved by the server. The server side scripting is done in coldfusion. I am trying to fetch the data in coldfusion and pass on the value back to iphone. I am not familiar much with coldfusion and wanted some help in this. Below is the coding in iphone:

/** Iphone code **/

NSString *post =[[NSString alloc] initWithString:@"Hello World"];
NSURL *url=[NSURL URLWithString:@"http://www.abc.com/test.cfm"];


NSData *postData = [post dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];


NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];

/* Coldfusion code * /

<html>
<head><title>Test</title></head>
<body>
<cfoutput>#form.post#</cfoutput>
</body>
</html>

Am I doing it correctly?

You may need to specify name of form variable in data. Try below for post variable. I haven't tested it should work.

NSString *post =[[NSString alloc] initWithString:@"post=Hello%20World"];
