I have write one method:
-(id)postAndParseJson:(NSMutableDictionary *)theDictionary action:(NSString *)action type:(NSString *)myType {
NSString *newJSON = [theDictionary JSONRepresentation];
NSLog(@"what to send: %@", newJSON);
NSURL *url = [NSURL URLWithString:@"http://api.uat.ushi.cn/user/getProfile?user_id=3"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
NSLog(@"to url = %@",url);
[request appendPostData:[newJSON dataUsingEncoding:NSUTF8StringEncoding]];
[request startSynchronous];
NSString *responseString = [request responseString];
NSMutableDictionary* responseDict = [responseString JSONValue];
NSLog(@"responseString = %@",responseString);
return responseDict;
}
the method is simple,just post the value and parse the return value,when I run it ,I get the console output:
2012-05-02 12:06:29.414 Ushi.com[775:f803] what to send: {"phone":"123456","password":"123456","user_name":"tan"}

(lldb)
and it crash!but if I comment the line[request appendPostData:[newJSON dataUsingEncoding:NSUTF8StringEncoding]];I will receive the data,but it also crash.
thank you in advance…
That’s because what you get from server is not a valid JSON, but a plain html.
The problem is that your server does not support POST , so it returns error page.
