使用 ZendFramework2 请求 Random.org API

Request to Random.org API with ZendFramework2

我是 ZF2 的新手,我想创建一些利用外部 API 的应用程序。我已经成功创建了向 random.org API 发送请求的方法,但作为响应,它向我发送了一个与解析相关的错误。我不知道我做错了什么,也不知道如何改进我的方法以获得正确的响应数据。

这是我用来发送请求的方法(我有意更改了 api 密钥,在我的应用程序中我使用了正确的密钥):

public function makeRequest()
{
    $data = array(
        'jsonrpc' => '2.0',
        'method' => 'generateIntegers',
        'params' => array(
            'apiKey' => '00000000-0000-0000-0000-000000000000',
            'n' => 10,
            'min' => 1,
            'max' => 10,
            'replacement' => true,
            "base" => 10),
        'id' => 23866,
    );

    $client = new Client('https://api.random.org/json-rpc/1/invoke', array(
        'adapter' => 'Zend\Http\Client\Adapter\Curl'
    ));
    $client->setEncType(Client::ENC_FORMDATA);

    $request = new Request();
    $request->setUri('https://api.random.org/json-rpc/1/invoke');
    $request->setMethod('POST');
    $request->getPost()->fromString(json_encode($data));
    $response = $client->send($request);

    return $response;
}

回复内容如下:

["content":protected]=> string(87) "{"jsonrpc":"2.0","error":{"code":-32700,"message":"Parse error","data":null},"id":null}

ZF2 Request Reference,你可以找到 setContent() 函数,你可以尝试用它代替 getPost()->fromString() 吗?

public function makeRequest()
{
    $data = array(
        'jsonrpc' => '2.0',
        'method' => 'generateIntegers',
        'params' => array(
            'apiKey' => '00000000-0000-0000-0000-000000000000',
            'n' => 10,
            'min' => 1,
            'max' => 10,
            'replacement' => true,
            "base" => 10),
        'id' => 23866,
    );

    $client = new Client('https://api.random.org/json-rpc/1/invoke', array(
        'adapter' => 'Zend\Http\Client\Adapter\Curl'
    ));
    $client->setEncType(Client::ENC_FORMDATA);

    $request = new Request();
    $request->setUri('https://api.random.org/json-rpc/1/invoke');
    $request->setMethod('POST');


    //$request->getPost()->fromString(json_encode($data));
    $request->setContent(json_encode($data));

    $response = $client->send($request);

    return $response;
}
