remain to be solved，My solution is for users to upgrade their phone system to the latest version

Can upgrading the user's iOS system to the latest version solve this problem? We also have macOS and Windows users here who encounter this problem. Once it occurs, they cannot access any network

The users I have encountered with problems are the older iOS version, such as the situation that the version has not been updated for several years, but some users are still unwilling to update the version, so this part of the use is still unable to use

same issue

[xiongzhaoxu]

I found my problem. It was because I set options.headers['deviceName'] = "xxxx". This place should be encoded.
options.headers['deviceName'] =
Uri.encodeComponent(info["deviceName"]!); // Encode the device name to prevent non-ASCII characters

Thanks！I will try it

抛出的异常里没有解释为什么异常？

抛出的异常里没有解释为什么异常？

我当时并没有去注意这个异常，后面找了几个用不了的用户，专门来打印异常信息看到， 是因为他们是旧版本的ios系统，还有windows系统，他们可以设置中文的设备名称，而中文的信息传递到options.headers，就会报错“ Non-ASCII characters in headers might cause exceptions thrown with DioExceptionType.unknown”
