Flutter DIO library XMLHttpRequest error Web

Question

我有工作与扑动DIO库。它在我的安卓应用程序上工作很好，但在网络上给出错误。Error: DioError [DioErrorType.response]: XMLHttpRequest error.

如果我用http尝试相同的url，它的工作很好。我的Dio Library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');

我试过其他论坛的答案，但没有帮助。

我的整个项目是基于Dio库。

我该怎么办?

Answer 1

我也遇到了同样的问题。但是经过一番研究，我找到了一个可行的解决方案:

1. 转到flutterbincache
2. 找到一个名为flutter_tools.stamp的文件，将其压缩为zip文件或其他文件以保留副本，然后删除原始文件。
进入flutterpackagesflutter_toolslibsrcweb并在编辑器中打开chrome.dart文件。
3. 查找'--disable-extension'
4. 注释掉并替换为--disable-web-security

快乐编码

如果你看到这个'你正在使用一个不支持的注释行标志:——disable-web-security。稳定和安全将受到影响在您的浏览器假定它。它只在本地环境中这样做，无需担心
