我已经在一个项目上工作了一段时间了。
功能：
问题：
{
"readyState": 4,
"responseText": "{\"error\":{\"code\":\"-1, Microsoft.SharePoint.Client.InvalidClientQueryException\",\"message\":{\"lang\":\"en-US\",\"value\":\"The parameter __metadata does not exist in method GetByTitle.\"}}}",
"responseJSON": {
"error": {
"code": "-1, Microsoft.SharePoint.Client.InvalidClientQueryException",
"message": {
"lang": "en-US",
"value": "The parameter __metadata does not exist in method GetByTitle."
}
}
},
"status": 400,
"statusText": "error"
}
我看了无数的YouTube视频教程，展示了如何解决错误/正确执行CRUD操作的过程，通过大量的堆栈溢出帖子以及sharepoint.stackexchange和MSDN进行了扫描，我很幸运地解决了该错误。我有点被困住了。
这是我的代码（实际的SharePoint baseurl已更改）：
function loadData() { //Initializing the AJAX Request function to load in the external list data from different subsites
//create an array of urls to run through the ajax request instead of having to do multiple AJAX Requests
var urls = ["https://baseurl.sharepoint.com/sites/Projects/USMC/AMMO/_api/web/lists/getbytitle('AMMO Deliverables')/items?$select=Program,Deliverable,To,Date,Approved,Notes",
"https://baseurl.sharepoint.com/sites/Projects/USMC/DARQ/_api/web/lists/getbytitle('Dar-Q Deliverables')/items?$select=Program,Deliverable,To,Date,Approved,Notes",

];

console.log(data);

更新： 所以现在我将PostItem函数更新为：
function PostItem() {
return getFormDigest("https://baseurl.sharepoint.com/sites/Projects/USMC/AMMO").then(function(digestData) {
console.log(digestData.d.GetContextWebInformation.FormDigestValue);
var item = {
"__metadata": { "type": "SP.Data.AMMODeliverablesListItem" },
"Title": "updated title",
"Program": $("#dProgram").val(),
"Deliverable": $("#dDeliverable").val(),
"To": $("#dTo").val(),
"Date": $("#dDate").val(),
"Approved": $("#dApproved").val(),
"Notes": $("#dNotes").val()
};
$.ajax({
async: true, // Async by default is set to “true” load the script asynchronously
// URL to post data into sharepoint list or your own url
url: "https://baseurl.sharepoint.com/sites/Projects/USMC/AMMO/_api/web/lists/getbytitle('AMMO Deliverables')",
method: "PATCH", //Specifies the operation to create the list item
data: JSON.stringify(item),
headers: {
"content-type": "application/json;odata=verbose",
"X-RequestDigest": digestData.d.GetContextWebInformation.FormDigestValue,
"Accept": "application/json;odata=verbose",
"If-Match": "*"
},
success: function(data) {
alert('Success'); // Used sweet alert for success message
console.log(data + " success in updating item");
},
error: function(data) {
alert(JSON.stringify(error));
console.log(data);
}
});
})
}
执行后，它会更改列表名称吗？为什么这样做而不像我试图告诉它那样将项目添加到列表中。此外，控制台不会显示任何错误。
在开发者控制台中的“网络”选项卡上浏览时，底部的请求有效负载还包括我要添加为SharePoint列表中的新项目的所有项目。
