我正在使用 Flutter DIO 库。它在我的 Android 应用程序上运行良好，但在 Web 上出现错误。 Error: DioError [DioErrorType.response]: XMLHttpRequest error.

如果我尝试使用 http 相同的 url，它在 Web 上工作正常。我的 Dio 库代码

Dio dio = Dio();
dio.options.method = "POST";
dio.options.headers["Access-Control-Allow-Origin"] = "*";
    dio.options.headers["Access-Control-Allow-Credentials"] = true;
    dio.options.headers["Access-Control-Allow-Headers"] =
        "Origin,Content-Type,X-Amz-Date,Authorization,X-Api-Key,X-Amz-Security-Token,locale";
    dio.options.headers["Access-Control-Allow-Methods"] =
        "GET, HEAD, POST, OPTIONS";
var response = await dio
        .post('http://45.79.124.182/app_php/PagarGuru_test/requestAdd.php');
