SharePoint REST API - 设置欢迎页面

Question

我正在尝试通过REST API设置SharePoint网站的欢迎页面。以下是我的代码：

def request_digest(self, site_url):

    api_call = "/_api/contextinfo"
    url = f"{site_url}{api_call}"

    headers = {
        "Authorization": f"Bearer {str(self.O365_TOKEN)}",
        "Accept": "application/json;odata=verbose"
        }
    
    response = requests.post(url, headers=headers)
    return data['d']['GetContextWebInformation']['FormDigestValue']
    
    

def set_homepage(self, site_url):

    RequestDigest = self.request_digest(site_url)


    api_call = "/_api/Web/RootFolder"

    url = f"{site_url}{api_call}"

    payload = {
                "__metadata": {
                    "type": "SP.Folder"
                },
                "WelcomePage": "SitePages/Home.aspx"
            }
    headers = {
        "X-HTTP-Method":"PATCH",
        "Authorization": f"Bearer {str(self.O365_TOKEN)}",
        "accept-language": "en-GB,en-US;q=0.9,en;q=0.8",
        "Accept": "application/json;odata=verbose",
        "Content-Type": "application/json;odata=verbose",
        "content-length": str(len(json.dumps(payload).encode('utf-8'))),
        "X-RequestDigest": RequestDigest,
        "IF-MATCH": "*"
        }
    
    response = requests.post(url, headers=headers, json=payload)

这是我收到的响应：

{"error": {"code": "-1, Microsoft.SharePoint.Client.InvalidClientQueryException", "message": "无效的请求"}}

希望能得到一些帮助。

我尝试过：

• 搜索资料，但每个来源（其实不多……）都说这个应该可以工作。我甚至用Fiddler检查了请求头和负载，但我发现的唯一不同是我使用的是OAUTH令牌，而不是x-requestdigest。

• 尝试过有和没有X-RequestDigest头，因为不清楚在使用OAUTH令牌时是否需要包含它（https://learn.microsoft.com/en-us/sharepoint/dev/sp-add-ins/complete-basic-operations-using-sharepoint-rest-endpoints#writing-data-by-using-the-rest-interface）

• 用requests.patch替代requests.post

• 其他API调用GET和POST都正常，我可以创建新网站，获取其属性等等……

谢谢，
Ben

你可以使用下面的代码来设置欢迎页面

function SetDefaultPage() {
    $.ajax
        ({ 
            url: _spPageContextInfo.webAbsoluteUrl + "/_api/web/rootfolder",
            type: "POST",
            data: JSON.stringify({
                '__metadata': {
                    // Type that you are modifying.
                    'type': 'SP.Folder'
                },
 
                'WelcomePage': 'SitePages/home.aspx'
            }),
            headers:
        {
            "Accept": "application/json;odata=verbose",
            "Content-Type": "application/json;odata=verbose",
            "IF-MATCH": "*",
            "X-HTTP-Method": "PATCH",
            "X-RequestDigest": $("#__REQUESTDIGEST").val()
        },
            success: function (data, status, xhr) {
                console.log("Success");
            },
            error: function (xhr, status, error) {
                console.log("Failed");
            }
        });
}
