使用Angular的Sharepoint API CORS访问

提问于

我会从SharePoint API获取数据 .

当我攻击API时，我收到CORS访问错误 .

这是我的服务 .

public getResults() {
    let url;
    let mockUrl;
    var headers = new HttpHeaders({
      "Content-Type": "application/json",
      "Access-Control-Allow-Credentials": "true",
      "Access-Control-Allow-Origin": "*"
    });

    url ="https://my.sharepoint.api";
    return this.httpClient
    .get(url, headers)      
 }

负责这个项目的团队告诉我他们正在使用其他角度应用程序，他们不需要更改他们的服务器配置（允许localhost调用）

这是我得到的回应：

GET https：//my.api.sharepoint 401（未授权）无法加载https：//my.api.sharepoint：请求的资源上没有“Access-Control-Allow-Origin”标头 . 因此不允许来源'http：// localhost：4200'访问 . 响应具有HTTP状态代码401 .

我怎么解决这个问题？

    我有同样的问题，我通过安装你可以在链接中找到的插件解决了客户端（如果你有铬） . 这是一个只有在你做一些测试时才有用的选项 .

    您需要为SharePoint 2013启用跨域调用（这不适用于SharePoint 2016） .

    并将http://localhost:31699添加到信任站点，以便请求将使用当前用户凭据进行身份验证 .
