A Native Collection has not been disposed, resulting in a memory leak. Enable Full StackTraces to get more details.
原因：
数据请求提交过程中，UnityWebRequest 不时出现数据没有释放的情况，偶尔会一部分数据
内存溢出情况：
解决方法：
UnityWebRequest 前加上using
IEnumerator Post(callBack call)
{
WWWForm form = new WWWForm();
form.AddField("name", "myData");
form.AddField("id", "myData");
form.AddField("message", "myData");
using UnityWebRequest www = UnityWebRequest.Post(HttpConfig.goServer_url+postUrl, form);
yield return www.SendWebRequest();
if (www.result != UnityWebRequest.Result.Success)
{
Debug.Log(www.error);
}
else
{
Debug.Log("Form upload complete!");
Debug.Log(www.downloadHandler.text);
}
}Curl error 28: Failed to connect to 10.110.83.193 port 1880 after 21043 ms: Timed out

许可证问题。
解决方法：
unity hub登出。

WebGL跨域问题
开发webgl的项目，在编译器里用get和post请求没问题，但是打包出来以后就出现问题了。
from origin 'file://' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
这种错误就是出现了跨域问题。一般这种问题我们都是交给写后端接口的同事来处理。
当然我们也有另外的处理方法，就是设置谷歌浏览器(chrome)允许跨域。文章来源：https://www.toymoban.com/news/detail-652820.html
直接创建chrome浏览器的快捷方式，在属性中找到打开路径，在…chrome.exe后面加上文章来源地址https://www.toymoban.com/news/detail-652820.html
--args --disable-web-security --user-data-dir="C:/ChromeDevSession"到了这里，关于Unity 爬坑日记（遇到小坑就记录一下）的文章就介绍完了。如果您还想了解更多内容，请在右上角搜索TOY模板网以前的文章或继续浏览下面的相关文章，希望大家以后多多支持TOY模板网！
