我想從xcode發送用戶名和密碼到我已經創建的php文件。由於我對xcode和php都是新手，爲了簡單應用程序的目的，用戶名和密碼是預定義的「123456」。我有很多麻煩發送用戶名和密碼到PHP網站，並收到回覆。當我的代碼通信並建立連接時，它不會讀取php文件中回顯的變量。相反，它會獲得頁面的完整源代碼。我的代碼如下：如何發送和接收來自Xcode（目標c）的數據到php
目標C代碼：
//我已經設置警報視圖，以及設置兩個按鈕（繼續= buttonIndex == 0和取消= buttonIndex == 1）
// The user continues from the alert view
if(buttonIndex==0)
{
NSString* username = @"123456";
NSString* pass = @"123456";
// I combine the two strings to send to the php page, and insert a : between the two strings
NSString* combined = [NSString stringWithFormat:@"%@:%@", username, pass];
NSString *post = combined;
// Now I attempt to post the data to the php page
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
NSURL *url = [NSURL URLWithString:@"http://www.sulaimanmajeed.com/login.php"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
[theRequest setHTTPMethod:@"POST"];
[theRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPBody:postData];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if(theConnection)
{
webData = [[NSMutableData data] retain];
}
else
{
}
}
}
現在，我也有需要被調用執行後，當其他方法：
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[webData setLength: 0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[webData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
[connection release];
[webData release];
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSString *loginStatus = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];
// NSLog(loginStatus);
dataOutput.text = loginStatus;
[loginStatus release];
[connection release];
[webData release];
}
我的PHP代碼是非常簡單的：
<?php
$usernameEntered = $_GET['user']; $passwordEntered = $_GET['pass']; $full = 'Choose';
$username = array(
"123456", "234567", "345678", "456789");
$password = array(
"123456", "234567", "345678", "456789");
$accounts = array(
"Chequings-874576",
"Savings-793756",
"Visa-018375",
"Mastercard-375836");
$b = 0; $elementsInArray = count($accounts);
$isTrue = "FALSE";
if (($usernameEntered== $username[0]) && ($passwordEntered == $password[0])) {
$isTrue = "TRUE"; } elseif ((usernameEntered == $username[1]) && ($passwordEntered == $password[1])) {
$isTrue = "TRUE"; } elseif ((usernameEntered == $username[2]) && ($passwordEntered == $password[2])) {
$isTrue = "TRUE"; } elseif ((usernameEntered == $username[3]) && ($passwordEntered == $password[3])) {
$isTrue = "TRUE"; } else {
$isTrue = "FALSE"; }
if($isTrue == "TRUE") { for ($i=0; $i < $elementsInArray; $i++) { $b = $i; $full = $full . ':' . $accounts[$b] ; }
echo $full;
}
if($isTrue == "FALSE") {
echo "error:error 2:test 1:test 2:test 3";
}
?>
所以，dataOutput.text應該返回一個「真」值，因爲我提供的用戶名和密碼是默認的「123456」。但dataOutput.text只返回網站的完整源代碼。有人能幫助我找出它爲什麼不會輸出真實信息，以及我的代碼出錯的地方嗎？我一直在爲此工作2天，而且我很難過。先謝謝你。
P.S.
我收到DataOutput中的輸出是：

如果您粘貼的是您的PHP代碼，則會出現嚴重的語法問題。您只需簡單地讓腳本無誤地運行就可以開始。 –
他說什麼......用'$ password [0]'而不是'password（0）'和'$ result_array [0]'而不是'$ result_array（0）'....'和'$ username [ 0]'而不是'username（0）'等等。 – glomad
仍然會得到一些[語法錯誤]（http://codepad.viper-7.com/ONSEkI），請先調試一下。 並且一個php代碼以'<？php'開頭而不是'
