我看到新的建议(从2019年年中开始)是使用PKCE的代码流,而不是SPA的隐式流。我有一个使用OIDC客户端的angular spa,它工作得很好,直到它调用返回cors错误的/token端点 Access to XMLHttpRequest at 'https://login.microsoftonline.com/xxx/oauth2/token' from origin 'http://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin
我编写了一个Asp.Net核心api,到目前为止它一直运行得很好,但是当我试图发送一个post请求时,它给了我Access to XMLHttpRequest at 'https://localhost:44339/api/drawing/checkout' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-C
我正在运行的角度9项目连接到消防基地。
我和CORS有问题,我有两个方案:
1.从我的防火墙数据库请求图像Url
ERROR: Access to XMLHttpRequest at 'https://firebasestorage.googleapis.com .... from origin 'http://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resour
在一个角7项目中,使用HttpClient,在单击按钮处理程序上有以下简单的代码行:
this.http
.get('http://localhost:30123/api/identity/name/' + this.name)
.subscribe((answer: Identity[]) => {
this.identities = answer; // debug does not get here...
});
这将在VSCode上的Console Debug选项卡上抛出此错误:

我有一个本地(角)客户机运行在端口4200 ()上,一个本地(快递)服务器运行在端口5000 ()上。每当我试图连接到我的服务器时,我都会收到这条消息。

我使用的是google firebase云函数。 当从客户端访问我的云函数时,我得到以下HttpError SyntaxError: Unexpected token S in JSON at position 0

我有.NET核心5.0webapi,我需要从一个角度应用程序中使用,它们都运行在同一台机器上。
我得到的错误是:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:5000/api/Game/GetPossibleMoves. (Reason: CORS request did not succeed).

我正在处理一个平均堆栈项目,同时与节点js调用通信时,我收到了一个错误,如下所示。
Access to XMLHttpRequest at 'http://localhost:5050/user/login' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin'
我有主要网站索引的分析网站。早些时候,我在上使用了PHP,但现在我尝试在上的nodejs中实现它,但我有一个问题。
从url获取文本文件中的数据对php没有任何问题,但是当我尝试使用JavaScript时,CORS策略会出现问题。
我的代码是:
function getText(){
var request = new XMLHttpRequest();
request.open('GET', 'https://www.webcoder.sk/config/devices.txt', true);
我在将Content-Type设置为image/png时,通过PUT请求从本地主机将文件上传到时遇到CORS错误

我第一次尝试在我的angular应用中使用web套接字建立连接。但是它不起作用,它取代了url路径。
我的套接字服务
public initSocket(): void {
this.socket = socketIo('http://11.11.11.111/demo-api/status/');

为什么我要重新考虑Cors Error
Access to XMLHttpRequest at 'http://localhost:5000/api/upload' from origin 'http://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
据我所知。在我的asp.net core web api中的启动类中启用了cors。
这是我
我正在运行angular 2应用程序(使用angular-cli)并进行服务器API调用(其中所有(*)的CORS访问是在API代码中实现的)。
现在,当我试图从angular 2应用程序进行API调用时,有时我从服务器得到的响应完全没有CORS问题,有时我得到了以下问题:
对于Chrome浏览器:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
XMLHttpRequest cannot load https://server.com/api/currenc
请阅读这个问题。我在堆栈溢出上尝试了所有的答案。
错误:
The value of the 'Access-Control-Allow-Origin' header in the response must
not be the wildcard '*' when the request's credentials mode is 'include'.
Origin 'http://localhost:4200' is therefore not allowed access. The
