NuSOAP - 函数参数未正确映射

发布于 2024-12-01 23:39:32 字数 1129 浏览 0 评论 0原文

我正在 PHP 中使用 NuSOAP 编写一个 Web 服务。为了测试它，我编写了服务器和客户端。在服务器端，我像这样注册该函数：

$server->register(
    "testFunction",
    array("param1" => "xsd:string", "param2" => "xsd:string"),
    array("result" => "xsd:string"),
    "http://localhost/testApp"
);

在客户端看起来像这样：

require_once("./lib/nusoap.php");

$client = new soapclient("http://localhost/testApp/server.php");
$function = $_GET["function"];
unset($_GET["function"]);
$result = $client->call($function, $_GET);

echo "<pre>". print_r($result, true) ."</pre>";

当我调用它时，

http://localhost/testApp/client.php?function=testFunction&param1=value1&param2=value2

它工作正常，但如果我切换 param1 和 param2 并说，

http://localhost/testApp/client.php?function=testFunction&param2=value2&param1=value1

然后 param1 获取值 value2 并且 param2 获取值 value1。显然，它只是按照参数的顺序，而不是名称。

我认为，由于我使用特定的参数名称注册了该函数，然后调用该函数并指定了这些参数名称，因此它们将被相应地分配。

我错过了什么吗？如果参数名称将被丢弃并按您输入的任何顺序分配，那么指定参数名称有何意义？有没有办法让我可以按任何顺序输入参数并让它们正确映射？

I'm writing a web service using NuSOAP in PHP. To test it, I have written both a server and a client. On the server end, I register the function like so:

$server->register(
    "testFunction",
    array("param1" => "xsd:string", "param2" => "xsd:string"),
    array("result" => "xsd:string"),
    "http://localhost/testApp"
);

And on the client looks like this:

require_once("./lib/nusoap.php");

$client = new soapclient("http://localhost/testApp/server.php");
$function = $_GET["function"];
unset($_GET["function"]);
$result = $client->call($function, $_GET);

echo "<pre>". print_r($result, true) ."</pre>";

When I call it like

http://localhost/testApp/client.php?function=testFunction¶m1=value1¶m2=value2

it works fine, but if I switch param1 and param2 and say

http://localhost/testApp/client.php?function=testFunction¶m2=value2¶m1=value1

then param1 gets the value value2 and param2 gets the value value1. So obviously, it just goes by the order of the parameters, not the names.

I figured that since I registered the function with specific parameter names and then called the function, specifying those parameter names, that they would be assigned accordingly.

Am I missing something? What's the point of specifying the parameter names if they will just be thrown out and assigned in whatever order you entered them? Is there a way to make it so that I can enter the parameters in any order and have them map correctly?

也许在客户端中使用默认地图：

    $default = array(
        'param1' => '',
        'param2' => 'test',
    );
    $params = $defaults;
    foreach ( $_GET as $param_name => $param_value ) {
        if ( isset( $params[ $param_name ] ) ) $params[$param_name] = $param_value;
    }
    $client->call( $function, $params );

简单的黑客，即使它并没有“真正”回答您的问题。

请注意，如果您希望客户端了解有关所进行的调用的格式的任何信息，则传递给客户端的 url 必须是 SOAP WSDL。是你的吗？（我已经使用 nuSoap 很长时间了，但我记得只需将“?wsdl”参数添加到服务器 url 就足以让服务器响应有效的 wsdl ）

maybe go for a default map in the client:

    $default = array(
        'param1' => '',
        'param2' => 'test',
    );
    $params = $defaults;
    foreach ( $_GET as $param_name => $param_value ) {
        if ( isset( $params[ $param_name ] ) ) $params[$param_name] = $param_value;
    }
    $client->call( $function, $params );

Simple hack, even though it doesnt "really" answer your questions.

One note, the url you're passing to the client MUST be a SOAP WSDL if you expect the client to know anything about the format of the calls being made. Is yours ? ( It's been a long time I've used nuSoap, but i recall simply adding "?wsdl" param to the server url was enough to have the server respond with a valid wsdl )
