Question

我尝试借助Webrequest，Sharepoint Online中的Button来触发。

第一个Errro代码：

异常调用＆＃34; GetResponse＆＃34;用＆＃34; 0＆＃34;参数：＆＃34;远程服务器返回错误：（403）禁止。＆＃34;

$solutionId = Get-SPOSolutionId -solutionName $solutionName

# Queries the solution's page
$operation = ""
if($activate) 
{ 
    $operation = "ACT" 
} 
else 
{ 
    $operation = "DEA" 
}

$solutionPageUrl = Join-SPOParts -Separator '/' -Parts $context.Site.Url, "/_catalogs/solutions/forms/activate.aspx?Op=$operation&ID=$solutionId"

$c

    # Hookup authentication cookie to request
    $cookieContainer.Add($fedAuth)

    $request.CookieContainer = $cookieContainer
}
else

    # No specific authentication required
    $request.UseDefaultCredentials = $true
}

$request.ContentLength = 0

$response = $request.GetResponse()

    # decode response

您是否已在清单文件中添加了外部端点。您需要添加端点的URL，以便应用程序具有访问外部端点的权限。

这是一个代码示例的链接，如何执行/查询外部端点和其他来源，例如：Web应用程序，主机应用程序或网站集等等。
