blocked by 和 is blocking在项目任务管理中是什么意思

"Blocked by"和"is blocking"是项目管理中常用的术语，用于描述任务之间的依赖关系。

"Blocked by"意味着某个任务无法继续进行，因为它依赖于另一个任务的完成。例如，如果任务B依赖于任务A的完成，则可以说任务B被任务A所阻塞。

另一方面，"is blocking"意味着某个任务阻止其他任务的进行。例如，如果任务A无法开始，因为任务B尚未完成，则可以说任务B正在阻止任务A的进行。

在项目管理中，了解任务之间的依赖关系非常重要，因为这有助于确定任务的优先级和时间表。

from origin 'http://localhost:8081' has been blocked by CORS policy

The CORS (Cross-Origin Resource Sharing) policy is a security measure implemented by web browsers to restrict access to resources (such as APIs) on a different origin (domain, protocol, or port) than the one the web page is served from.

In your case, it seems that you are making a request from 'http://localhost:8081' to a different origin, and the server is blocking that request due to CORS policy restrictions. To resolve this issue, you can try the following solutions:

1. Enable CORS on the server-side: If you have control over the server-side code, you can configure the server to include the appropriate CORS headers in the response. These headers allow the browser to determine if it should allow the request. The minimal required headers are 'Access-Control-Allow-Origin' and 'Access-Control-Allow-Methods'. You can set the value of 'Access-Control-Allow-Origin' to '*' to allow requests from any origin during development. However, in production, it's recommended to set it to the specific origin of your application.

2. Use a proxy server: If you don't have control over the server-side code or enabling CORS is not feasible, you can set up a proxy server that acts as an intermediary between your client-side code and the server. Your client-side code will make requests to the proxy server, and the proxy server will forward those requests to the actual server. Since the proxy server will be on the same origin as your client-side code, you won't face any CORS issues.

3. Disable CORS in the browser: Although not recommended for production environments, during development, you can disable CORS checks in your browser. Keep in mind that this is a temporary solution and should not be used in a production environment. The method to disable CORS varies between browsers, so you need to search for instructions specific to your browser.

Remember to consider security implications when implementing any solution and ensure that proper CORS configurations are applied in a production environment.

此代码是与后端的接口吗A parser-blocking, cross site (i.e. different eTLD+1) script, http://api.map.baidu.com/getscript?v=3.0&ak=dWg6zG5GweG0e7wB14K7bFMGktVG2kzR&services=&t=20230512140248, is invoked via document.write. The network request for this script MAY be blocked by the browser in this or a future page load due to poor network connectivity. If blocked in this page load, it will be confirmed in a subsequent console message. See https://www.chromestatus.com/feature/5718547946799104 for more details.

这个代码是一个警告信息，它告诉您当前网页中有一个脚本文件（http://api.map.baidu.com/getscript），它是通过 `document.write` 方法调用的。它还提醒您，由于网络连接不良，浏览器可能会阻止加载该脚本文件，这可能会影响网页的正常运行。如果该脚本被阻止，将会在后续的控制台消息中进行确认。您可以查看链接 https://www.chromestatus.com/feature/5718547946799104 以获取更多详细信息。这段代码并不是与后端接口有关，它只是一个 JavaScript 脚本文件，可能是用来获取地图或者其他功能。
