Question

这段代码在flashplayer 11中有效，但它在flashplayer 14中无效。

AS3代码：

private function savePDF(pdfBinary:ByteArray, urlString:String):void{

try{

    //result comes back as binary, create a new URL request and pass it back to the server
    var header:URLRequestHeader = new URLRequestHeader("Content-type", "application/octet-stream");

    var sendRequest:URLRequest = new URLRequest(urlString);
        sendRequest.requestHeaders.push(header);
        sendRequest.method = URLRequestMethod.POST;
        sendRequest.data = pdfBinary;                
        sendToURL(sendRequest);

    } catch (e:Error) {
        // handle error here
        trace("Error in savePDF "+e.message);
        trace("StackTrace : "+e.getStackTrace());
    }

}

这些是我得到的错误：

Error in savePDF Error #3769: Security sandbox violation: Only simple headers can be used with navigateToUrl() or sendToUrl().
StackTrace : SecurityError: Error #3769: Security sandbox violation: Only simple headers can be used with navigateToUrl() or sendToUrl().

针对此问题的任何修复？

Answer 1

您可以首先使用try和catch开头：

try {
    sendToURL(request);
}
catch (e:Error) {
    // handle error here
}

如果在开发环境中看不到问题，我建议您安装一个Flash调试播放器，您可以在此处下载：Flash Player Downloads以查看您的代码将触发的错误类型。

如果您的代码没问题，那么在dev和prod环境中，您应该调试服务器端脚本。

sendToURL无法在flashplayer 14中工作
