Question

好的，所以我的iOS应用需要发送Latitude＆amp;通过HTTP POST方法接收郊区的经度。

这是我获取Lat＆amp; amp; amp; amp;经度

float lat = locationManager.location.coordinate.latitude;
float lon = locationManager.location.coordinate.longitude;

我想用这样的HTTP POST方法发送它

here is the problem
NSString *post = @"key1=val1&key2=val2";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"http://www.nowhere.com/sendFormHere.php"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

我想知道的是，我是否可以将float部分更改为字符串或类似于HTTP POST方法中使用的内容

Answer 1

您可以创建帖子：

NSString *post = [NSString stringWithFormat:@"lat=%f&lon=%f", lat, lon];

Answer 2

当然，你可以在身体中添加浮动：

NSString *post = [NSString stringWithFormat:@"lat=%f,long%f",lat,lon];

Lat Lon通过HTTP POST
