在 PHP 中使用 ->instance_url 的正确方法？(网络接口)

Question

我需要在php curl发送自定义HEADER, post在XML或json，并在web api返回响应。搜索，我发现这个尝试解决我的问题与not found requests:

    $ch = curl_init();
LINE 112    curl_setopt($ch, CURLOPT_URL, $urlCall->instance_url . $request);
    ..

是指:

$urlCall = https://ip.andress/v1/requestActivateCode/;

和$request是一个json参数编码(只是测试):

$params = array("RetailTransactionRequest" =>
    array(
        "code" => "0000002381237220",
        "amount" => $amount,
        "upc" => $upc,
        "transactionID" => "1234",
        "dateTime" => $xIncommDateTime,
        "retailerName" => $retailerName
    )
);
$request = json_encode($params);

好吧…但是结果是:

Notice: Trying to get property of non-object in /home/ubuntu/public_html/ip.adress/public/test.php on line 112
Curl error: Could not resolve host: {"RetailTransactionRequest":{"code":"0000002381237220","amount":"20.00","upc":"799366289999","transactionID":"1234","dateTime":"2015-06-08T09:09

custom HEADER的信息为:bool(false)

我需要在服务器API中张贴数组，并在php文件....中从服务器接收答案为什么不工作?谢谢。

你的代码有两个缺陷:

<<p> 1日/strong>

根据你的说法，$urlCall是string。因此，您不需要通过使用$urlCall->instance_url来检索它的值。只使用$urlCall。

你不能把你的JSON字符串附加到你调用的URL。你需要使用CURLOPT_POSTFIELDS。

因此，您的代码需要如下:

$urlCall = 'https://ip.andress/v1/requestActivateCode/';
$params = array("RetailTransactionRequest" =>
    array(
        "code" => "0000002381237220",
        "amount" => $amount,
        "upc" => $upc,
        "transactionID" => "1234",
        "dateTime" => $xIncommDateTime,
        "retailerName" => $retailerName
    )
);
$request = json_encode($params);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $urlCall); // note the use of $urlCall
curl_setopt($ch, CURLOPT_POSTFIELDS, $request); // this passes the JSON string to the server
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($request))                                                                       
); // this is to tell the server that the request contains JSON
