Paypal-php-sdk中的PayPal模拟响应

Question

如何使用Paypal-php-sdk使用否定测试。我尝试将标头添加到api上下文中，但始终会收到以下响应：

{
    "name": "INVALID_NEGATIVE_TESTING_INPUT",
    "message": "Invalid input found. See the following supported cases.",
    "links": [
        {
            "href": "https://developer.paypal.com/docs/api/nt-rest/",
            "rel": "information_link"
        }
    ],
    "details": [
        {
            "issue": "You must use a valid URL supported by negative testing."
        }
    ]
}

我发送了标头

PayPal-Mock-Response: {"mock_application_codes":"AUTHORIZATION_VOIDED"}

在我的PHP代码中

    $i_header["header"] = "PayPal-Mock-Response";
    $i_header["value"] = json_encode(["mock_application_codes" => "INSTRUMENT_DECLINED"]);

    $o_apiContext->addRequestHeader($i_header["header"], $i_header["value"]);

测试输入的完整列表，网址为 https://developer.paypal.com/docs/api/payments/#errors

有什么建议么？谢谢

这段代码对我来说效果很好：

$apiContext->addRequestHeader("PayPal-Mock-Response", "{'mock_application_codes':'INSTRUMENT_DECLINED'}");
