我從我的iPhone應用程序發佈一個變量「節」到一個PHP的Web服務。此網頁查看是否部分isset詢問進行數據檢索數據庫之前..iPhone應用開發 - 從PHP發送和接收數據
我用下面的方法來發布數據:
+(void)getQuestions:(NSInteger)sectionId from: (NSString*) url{
//connect to database given by url
NSMutableString* myRequestString = [[NSMutableString string]initWithFormat:@"section=%@", sectionId];
NSData *myRequestData = [NSData dataWithBytes: [myRequestString UTF8String] length: [myRequestString length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL: [NSURL URLWithString: url]];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];
[request setHTTPMethod: @"POST"];
//post section
[request setHTTPBody: myRequestData];
}
在相同的方法,我想捕捉迴盪着陣列php文件:
<?php
//connect to database
function connect() {
$dbh = mysql_connect ("localhost", "abc", "defgo") or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db("PDS", $dbh);
return $dbh;
}
//store posted data
if(isset($_POST['section'])){
$dbh = connect();
$section = $_POST['section'];
$query = mysql_query("SELECT * FROM QUESTIONS WHERE sectionId = $section;") or die("Error: " . mysql_error());;
$rows = array();
while($r = mysql_fetch_assoc($query)) {
$rows[] = $r;
}
echo $rows;
mysql_close();
}
?>
目標C API的哪些部分允許您捕獲響應數據?我如何修改上面的目標c函數來存儲$ rows變量?
的$行變量是一個關聯數組從數據庫中存儲的元組..
