我正在开发一个必须调用 PHP Web 服务的应用程序。我正在传递所有提到的参数，但响应仍然给出没有空字符串的输出。
这些是 PHP Web 服务的以下参数：
method: POST
parameters: {
title fname lname conNo pwd email city state country
}
这些是成功和不成功响应的条件：
Respons:
case a: On Sucessfull Registration
{
'userName' : 'fName', 'outhProvider' : 'normal', 'status' : 'success' 'userId' : 'userId',
'title' : 'title', 'firstName' : 'fName', 'lastName' : 'lName', 'city' : 'city', 'contactNo' : 'conNo', 'state' : 'state',
'country' : 'country'
}
case b: On Duplicate Registration
{
“status” : “Data already exist” }
case c: On Data not sufficient
{
“status” : “No data supplied” }
我使用的 Post 方法是：-
-(void)RegisterUser
{
NSString *strnew=[[NSString alloc]init];
strnew=@"buyer";
SBJSON *json = [SBJSON new];
json.humanReadable = YES;
responseData = [[NSMutableData data] retain];
NSString *service = @"http://www.ajatus.in/ajatus_templates/Templaton/wp-content/plugins/realestate/registrationJson.php";
NSString *requestString = [NSString stringWithFormat:@"{\"title\":\"%@\",\"fName\":\"%@\",\"lName\":\"%@\",\"conNo\":\"%@\",\"pwd\":\"%@\",\"email\":\"%@\",\"city\":\"%@\",\"state\":\"%@\",\"country\":\"%@\"}",titlename.text,fname.text,lname.text,contactno.text,password.text,email.text,city.text,state.text,country.text];
NSData *requestData = [NSData dataWithBytes: [requestString UTF8String] length: [requestString length]];
NSString *urlLoc=@"";
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];
self.connection = [NSURLConnection connectionWithRequest:request delegate:self];
}
