Http send() 请求不返回任何值

Question

我想知道为什么我的更新没有填充本地 Sqlite 数据库。昨天数据库应用程序中很少有记录正常工作。今天在插入另外 10 条记录后。两种发送方法似乎都可以正常工作，但它们不返回数据。它只更新 IngredientDB 而不是 RecipeID Request 。这是我的更新动作脚本代码，

 dishName.addEventListener("Success", dishName_resultHandler);
dishName.addEventListener("...", faultHandler);
dishName.send();
dishIngs.addEventListener("Success", ingredients_resultHandler);
dishIngs.addEventListener("...", faultHandler);
dishIngs.send();
protected function dishName_resultHandler(event:ResultEvent):void
{
externalRecipes=event.result.recipes.recipe;
}

protected function ingredients_resultHandler(event:ResultEvent):void{
externalIngredients=event.result.ingredients.ingredient;
}

这是我的第一个表的 php 脚本

$mysql_host = "...";
$mysql_database = "...";
$mysql_user = "...";
$mysql_password = "....";

$conn = mysql_connect("...", "...","...") or      die(mysql_error());
mysql_select_db("....", $conn);

$sql = 'SELECT * FROM `RecipeDB`';
$res = mysql_query($sql);

$xml = new XMLWriter();

$xml->openURI("php://output");
$xml->startDocument();
$xml->setIndent(true);

$xml->startElement('recipes');

while ($row = mysql_fetch_assoc($res)) {
$xml->startElement("recipe");

    $xml->writeElement('RecipeID', $row['RecipeID']);
    $xml->writeElement('Name', $row['Name']);
    $xml->writeElement('Category', $row['Category']);
    $xml->writeElement('Origin', $row['Origin']);
    $xml->writeElement('Recipe', $row['Recipe']);
    $xml->writeElement('Favorite', $row['Favorite']);
    $xml->writeElement('Image', base64_encode($row['Image']));



$xml->endElement();
}

$xml->endElement();

$xml->flush();

第二个类似

$conn = mysql_connect("...", "..","...") or die(mysql_error());
mysql_select_db("....", $conn);

$sql = 'SELECT * FROM `IngredientDB`';
$res = mysql_query($sql);

$xml = new XMLWriter();

$xml->openURI("php://output");
$xml->startDocument();
$xml->setIndent(true);

$xml->writeRaw('<?xml version="1.0"?>');
$xml->startElement('ingredients');

while ($row = mysql_fetch_assoc($res)) {
$xml->startElement("ingredient");

    $xml->writeElement('rowid', $row['rowid']);
    $xml->writeElement('RecipeID', $row['RecipeID']);
    $xml->writeElement('Ingredient', $row['Ingredient']);
    $xml->writeElement('Quantity', $row['Quantity']);



$xml->endElement();
}

这是我对服务器的调用

 <s:HTTPService id="dishName"
 url="http://.../dish.php"
 result="dishName_resultHandler(event)"
 fault="faultHandler(event)"/>

 <s:HTTPService id="dishIngs"
 url="http://.../Ingedient.php" 
 result="ingredients_resultHandler(event)"
 fault="faultHandler(event)"/>

这是我的数据库结构

CREATE TABLE `RecipeDB` (
`RecipeID` int(5) NOT NULL AUTO_INCREMENT,
`Name` varchar(20) COLLATE latin1_general_ci NOT NULL,
`Category` varchar(20) COLLATE latin1_general_ci NOT NULL,
`Origin` varchar(20) COLLATE latin1_general_ci NOT NULL,
`Recipe` varchar(2000) COLLATE latin1_general_ci NOT NULL,
`Favorite` tinyint(1) NOT NULL,
`Image` blob NOT NULL,
 PRIMARY KEY (`RecipeID`)
)

CREATE TABLE `IngredientDB` (
`rowid` int(5) NOT NULL AUTO_INCREMENT,
`RecipeID` int(5) NOT NULL,
`Ingredient` varchar(20) COLLATE latin1_general_ci NOT NULL,
`Quantity` varchar(100) COLLATE latin1_general_ci NOT NULL,
 PRIMARY KEY (`rowid`)
)

Answer 1

您如何配置您的网络服务器？也许这是您脚本上的 php 错误，而您没有得到答案，因为服务器（或 mayeb php）配置为不显示错误。

你检查过你的错误日志吗？您也可以尝试直接执行 php 文件，而不是通过 Flash 执行，以确保 URL 正确且答案格式正确。

希望这会有所帮助！
