UPDATE無法從iOS的
添加進入的MySQL儘管不同的崗位在這裏,我還沒有找到一個解決方案,加入我的MySQL表中的條目。我從iOS應用發佈了一個json字典,我想將其輸入到數據庫中。它由一個有4個字段(名字,姓氏...)的條目組成。下面是在服務器端的PHP代碼(與MAMP本地運行):
<?php
DEFINE('DB_USERNAME', 'root');
DEFINE('DB_PASSWORD', 'root');
DEFINE('DB_HOST', 'localhost');
DEFINE('DB_DATABASE', 'syncList');
$mysqli = new mysqli(DB_HOST, DB_USERNAME, DB_PASSWORD, DB_DATABASE);
if (mysqli_connect_error()) {
die('Connect Error (' . mysqli_connect_errno(). ') ' . mysqli_connect_error());
}
$body = file_get_contents('php://input');
$jsonArray = json_decode($body);
echo json_encode($jsonArray); // ---> send back for testing.
$firstname = $jsonArray['firstname'];
$firstname = $mysqli->real_escape_string($firstname);
$lastname = $jsonArray['lastname'];
$lastname = $mysqli->real_escape_string($lastname);
$eds = $jsonArray['eds'];
$dateOfBirth = $jsonArray['dateOfBirth'];
$sql = "INSERT INTO tbl_syncList (firstname, lastname, EDS, dateOfBirth) VALUES ('$firstname', '$lastname', '$eds', '$dateOfBirth')";
if ($mysqli->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $mysqli->error;
}
$mysqli->close();
?>
這個問題似乎是我的json_array [關鍵](如「$姓」)無法識別,因爲當我寫我json_array到文件,我看,關鍵是方括號裏面一樣,如果它是一個元素的數組:
stdClass Object
(
[firstname] => Robert
[eds] => 1234567
[lastname] => Redford
[dateOfBirth] => 12.01.1965
)
這是一個正常的發現或可能解釋爲何我不能在我的SQL提取值聲明?即使我使用json_decode($ body,TRUE),我無法返回數組對象而不是stdClass對象。
我添加用POST方法發送我的字典的obj-C代碼。這是調用上面的PHP腳本。
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate:nil delegateQueue: [NSOperationQueue mainQueue]];
NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] init];
[dictionary setValue:@"Robert" forKey:@"firstname"];
[dictionary setValue:@"Redford" forKey:@"lastname"];
[dictionary setValue:@"1234567" forKey:@"eds"];
[dictionary setValue:@"12.01.1965" forKey:@"dateOfBirth"];
NSError *error;
//serialize the dictionary data as json
NSData *data = [NSJSONSerialization dataWithJSONObject:dictionary options:0 error:&error];
NSString *urlString = @"http://192.168.1.106:8888/postPerson.php";
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setHTTPBody:data]; //set the data as the post body
[urlRequest addValue:@"postValues" forHTTPHeaderField:@"METHOD"];
[urlRequest setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[urlRequest setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[urlRequest addValue:[NSString stringWithFormat:@"%d",data.length] forHTTPHeaderField:@"Content-Length"];
NSURLSessionDataTask *dataTask =[defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *dataRaw, NSURLResponse *response, NSError *error) {
NSDictionary *json = [NSJSONSerialization
JSONObjectWithData:dataRaw
options:kNilOptions error:&error];
NSString *result = [NSString stringWithFormat:@"%@", json];
if (error) {
UIAlertView * av = [[UIAlertView alloc] initWithTitle:[NSString stringWithFormat:@"Got error %@.\n", error] message:nil delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[av show];
}
UIAlertView *av = [[UIAlertView alloc] initWithTitle:result message:nil delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[av show]; // --> this is to check the array sent with POST-method which is json_encode() in the php script above.
我希望這可能是有用的...
感謝您的回覆,但不幸的是這並沒有成功。我在直接傳遞字符串時也遇到了同樣的問題(比如VALUES('string1','string2'等),它似乎在瀏覽器中運行腳本時工作,但不能從我的應用程序中運行...我以爲是一個obj-C錯誤,但我收到我的應用程序中的json_encode()響應,所以腳本也被執行了。我瘋了... – Trichophyton 2015-03-09 17:16:50
實際上,它看起來像php://中的$ body(form POST方法)輸入是正確的,因爲它產生一個數組我可以json_encode()並返回到我的應用程序(我在UIAlertView中看到的結果),但這聽起來像sql語句不被調用,因爲它不工作。不是隻從我的應用程序調用,因爲我可以從默認字符串(VALUES('string1'...)我的瀏覽器添加mySQL數據庫中的條目我找不出什麼問題... – Trichophyton 2015-03-09 17:25:17
@Trichophyton你'如果你可以發佈更多的代碼並且相對於你剛纔所說的話,它會幫助我或者其他跟蹤你的問題的人,希望給你正確的解決方案。 – 2015-03-09 17:27:10
