我无法访问我的自定义Magento API？

Question

我是Magento的新手。我创建了自定义的Magento API以遵循 Marius说明.

我的代码是：

app/code/local/course/mca/etc/api.xml- API声明文件。

 <?xml version="1.0"?>
<config>
    <api>
        <resources>
            <mca_mca translate="title" module="mca">

        $result = Mage::helper('api')->wsiArrayPacker($result);
        return $result;
    }

}

它正在显示SOAP/XML-RPC列表以及WSDL，我创建了用户名和API，以允许访问MCA API。

最后，我调用我的PHP文件，它正在返回错误。

我的PHP代码是：

 <?php 
//$proxy = new SoapClient('http://localhost/ics/index.php/api/soap?wsdl'); //edit the address and put the url to your magento here
//$proxy = new SoapClient('http://localhost/ics/index.php/api/?wsdl');
try
{

$proxy = new SoapClient('http://localhost/ics/index.php/api/v2_soap?wsdl');
$sessionId = $proxy->login("magento","magento@123"); // put in the info for your user here
echo "Login ID : $sessionId";

echo '<br/>';

//$params = array('param1'=>'Dotnet','param2'=>'Php','param3'=>'9676588589');

//v1
//$result = $proxy->call($sessionId, 'mca.create',$params);

//v2
$result = $proxy->mcaMcaCreate($sessionId, 'Dotnet','Php','9676588589');

print_r($result); 


$proxy->endSession($sessionId);
} catch (Exception $e) {
    echo '<h1>Error</h1>';
    echo '<p>' . $e->getMessage() . '</p>';
}

错误是：

提前致谢。

Answer 1

这是一种错误，表明Magento找不到API的方法。因此，您有一个问题，如何在API.xml中定义此方法。顺便说一句，我看到了几个潜在的问题。见下文

• 您无需再次创建公共功能 create 在你的班上 Course_Mca_Model_Mca_Api_V2 因为你扩展 Course_Mca_Model_Mca_Api 而且这个方法具有相同的方法。
• 您的方法 Course_Mca_Model_Mca_Api::create 在WSDL定义中，您期望字符串作为参数和字符串作为返回的值，您定义了一种数组（无论如何，这是错误定义的）。为了您的测试目的，并允许您进行逐步编码，请执行：

替换为wsdl.xml

<message name="mcaMcaCreateRequest">
    <part name="sessionId" type="xsd:string" />
    <part name="data" type="typens:mcaMcaCreateEntity" />
</message>
<message name="mcaMcaCreateResponse">
    <part name="result" type="xsd:int"/>
</message>

和

<message name="mcaMcaCreateRequest">
    <part name="sessionId" type="xsd:string" />
    <part name="data" type="xsd:string" />
</message>
<message name="mcaMcaCreateResponse">
    <part name="result" type="xsd:string"/>
</message>

• 您还必须像wsdl.xml文件一样更新wsi.xml文件
• 进入api.xml，您也许也有一些问题，请执行以下操作：

代替

    <resources_alias>
        <mca>mca_mca</mca>
    </resources_alias>
    <v2>
        <resources_function_prefix>
            <mca>mcamca</mca>
        </resources_function_prefix>
    </v2>

和

    <resources_alias>
        <mca>mca_mca</mca>
    </resources_alias>
    <v2>
        <resources_function_prefix>
            <mca>mcaMca</mca>
        </resources_function_prefix>
    </v2>

然后在您的测试代码中使用V2 SOAP版本

$proxy = new SoapClient('http://localhost/ics/index.php/api/v2_soap?wsdl');
$sessionId = $proxy->login('magento', 'magento@123');
$result = $proxy->mcaMcaCreate($sessionId, 'my text test');
print_r($result);

Answer 2

这是你的问题。
在 api.xml 你有这个：

<resources>
    <mca translate="title" module="mca">
        <title>Mca API</title>
        ....

应该是

<resources>
    <mca_mca translate="title" module="mca">
        <title>Mca API</title>
        ....

如果您仔细观察我给的示例 这里, ，在api.xml中有这个

<api>
    <resources>
        <portfolio_project translate="title" module="portfolio">

所以标签 <resources> 应该 <[module]_[entity]>. 。在您的情况下，模块和实体具有相同的名称 mca, ，所以应该是 <mca_mca>
