我的代码在设备中工作正常，但我在chrome中出现错误，如果有人知道为什么请帮助我

解决方案

CORS实际上指定在AJAX调用时应向服务器发出两个请求（如果适用某些条件，如发送自定义标头）。 / p>

第一个请求（具有 OPTIONS 方法的请求）在飞行前被调用，用于检查它是否是安全地将完整的请求发送到服务器。来自服务器的响应应包含有效的 Access-Control-Allow-Origin 标头，其中包含客户端的URL或 * 。

您的服务器（而不是客户端）是需要支持CORS的服务器。您似乎正在使用.Net，因此您可能需要查看此处配置IIS。

解决方案

CORS actually specifies that two requests should be made to the server on an AJAX call (if certain conditions apply, like sending custom headers).

The first request (the one with the OPTIONS method) is called pre-flight and is used to check if it's safe to send the full request to the server. The response from the server should contain a valid Access-Control-Allow-Origin header containing the URL of the client or *.

Your server (and not the client) is the one that needs to support CORS. It seems you are using .Net for it, so you may want to take a look here on how configure IIS.
