我试图让POST消息正常工作。我看过一些描述如何做到这一点的帖子,比如这篇,但我仍然无法使其正常工作。以下是我的Objective-C代码:
NSString * urlString = @"http://magicthegatheringdatabase.com/test.php";
NSURL *aUrl = [NSURL URLWithString: urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:aUrl
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
NSString *postString = [NSString stringWithFormat:@"tes1=%@&test2=%@",
[@"hello" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
[@"world" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSData * postBody = [postString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody: postBody];
[request addValue:@"application/x-www-form-urlencoded; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
NSString *postLength = [NSString stringWithFormat:@"%d", postBody.length];
[request addValue: postLength forHTTPHeaderField:@"Content-Length"];
[request setHTTPMethod:@"POST"];
NSError * error = nil;
NSData *returnData = [NSURLConnection sendSynchronousRequest: request
returningResponse: nil
error: &error];
NSLog(@"%p, %@", error, error.localizedDescription);
NSString * returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"Result: %@", returnString);
这里是我的PHP代码:
<?php
print_r($_REQUEST);
print_r($_POST);
print_r($_GET);
echo file_get_contents( 'php://input' );
?>
如果我运行代码,我会得到以下日志记录:
2012-12-19 09:24:09.061 MTG Deck Builder[7921:570f] 0x0,(null) 2012-12-19 09:24:09.062 MTG Deck Builder[7921:570f] 结果:数组 ( ) 数组 ( ) 数组 ( )
如果我直接导航到URL并附加
?test1=hello&test2=world
(显然使用GET而不是POST),我会得到:数组 ( [test1] => hello [test2] => world [phpbb3_5e63r_u] => 1 [phpbb3_5e63r_k] => [phpbb3_5e63r_sid] => 7ff37e188aa8e0ab57fae6a52f0d1f7b [__utma] => 86369156.392372889.1349352986.1352901458.1353328580.11 [__utmz] => 86369156.1351935106.8.2.utmcsr=hankinsoft.com|utmccn=(referral)|utmcmd=referral|utmcct=/website/forum/10-mtg-magic-the-gathering-trading-card-game-tcg-da/634-new-forum.html [style_cookie] => null ) 数组 ( ) 数组 ( [test1] => hello [test2] => world )
所以我知道我的PHP正在正确记录get/requests,但我不确定为什么我的objective-c代码的POST无法工作。我相信我正在忽略一些愚蠢的东西。您对我错过了什么有何建议?
