使用相同的API访问同一环境中的Web API。具体而言，需要确保使用的是相同的scopes和redirectUri，并确保在应用程序注册页面上为相同的应用程序定义了正确的回调URI。以下是代码示例：

var msalConfig = {
    auth: {
        clientId: 'your_client_id',
        redirectUri: 'https://localhost:3000/auth.html',
        authority: 'https://login.microsoftonline.com/common',
        validateAuthority: true,
        navigateToLoginRequestUrl: false,
    },
    cache: {
        cacheLocation: 'localStorage',
        storeAuthStateInCookie: false,
    },
}

// Create the main MSAL instance
var msalInstance = new msal.PublicClientApplication(msalConfig);

// Login using the same scopes and redirectUri for all environments
msalInstance.loginPopup({ scopes: ['user.read'], redirectUri: 'https://localhost:3000/auth.html' })
    .then(function (response) {
        // Use the same access token for all environments
        var token = response.accessToken;
        console.log(token);
        // Call the API using the same scopes and access token for all environments
        callApi('https://your-web-api.com/api/data', token, ['user.read'])
            .then(function (response) {
                console.log(response);
            })
            .catch(function (error) {
                console.log(error);
            });
    })
    .catch(function (error) {
        console.log(error);
    });
