我有一个使用 REST API 和 Angularjs 从多个 SharePoint 2013 列表中获取数据的场景。我能够从 SharePoint 列表之一成功获取数据，但我的要求是从页面加载时的多个列表中获取数据。我正在使用提供商托管的应用程序从主机 Web 获取数据。我有 2 种方法可以调用 2 个单独的列表。我成功地从第一种方法获得结果，但是在执行第一种方法后调用第二种方法时。我收到超时错误。似乎我不能一个接一个地调用这两种方法。下面是我的代码，如果我遗漏了什么或者有任何其他方法可以从多个 SharePoint 列表中获取数据，任何人都可以帮助我。
方法 1：从列表 1 中获取数据
var query = listEndPoint + "/getbytitle('CandidateList')/items?$select=ID,FirstName,MiddleInitial,LastName,EmailAddress,PrimaryPhoneNo,ProfileImage,Address,State,Country,CurrentTitle,CurrentCompany,LastActivityModifiedBy,LastActivityModifiedDate,DeletedStatus&@target='" + hostweburl + "'";
var getCandidates = function (query, queryCandidateNotes)
{
alert('getRequest');
var scriptbase = hostweburl + "/_layouts/15/";
var deferred = $q.defer();
// Load 15hives js files and continue to the successHandler
$.getScript(scriptbase + "SP.Runtime.js",
function () {`enter code here`
$.getScript(scriptbase + "SP.js",
function () {
$.getScript(scriptbase +"SP.RequestExecutor.js",
function () {
var executor = new SP.RequestExecutor(appweburl);
executor.executeAsync({
url: query,
method: "GET",
headers: { "Accept": "application/json; odata=verbose" },
success: successHandler,
error: errorHandler
});
//deferred.resolve();
});
});
});
function successHandler(data) {
var jsonObject1 = JSON.parse(data.body);
deferred.resolve(jsonObject1);
}
function errorHandler(data, errorCode, errorMessage) {
alert('Error1:' + errorMessage + data.body);
}
// Get
return deferred.promise;
//Candidate Details Ends
};
方法 2：从列表 2 中获取数据
var queryCandidateNotes = listEndPoint + "/getbytitle('CandidateNotes')/items?$select=Title,CandidateId&@target='" + hostweburl + "'";
// Get All Candidate Notes
var getCandidateNotes = function (queryCandidateNotes) {
alert('getCandidateNotesRequest');
var scriptbase = hostweburl + "/_layouts/15/";
var deferred2 = $q.defer();
// Load 15hives js files and continue to the successHandler
$.getScript(scriptbase + "SP.Runtime.js",
function () {
$.getScript(scriptbase + "SP.js",
function () {
$.getScript(scriptbase + "SP.RequestExecutor.js",
function () {
var executor = new SP.RequestExecutor(appweburl);
executor.executeAsync({
url: queryCandidateNotes,
method: "GET",
headers: { "Accept": "application/json; odata=verbose" },
success: successHandler,
error: errorHandler
});
//deferred.resolve();
});
});
});
function successHandler(data) {
var jsonObject2 = JSON.parse(data.body);
//var results2 = jsonObject2.d.results;
deferred2.resolve(jsonObject2);
//alert('2nd success:' + jsonObject2);
//return jsonObject2;
}
function errorHandler(data, errorCode, errorMessage) {
alert('Error2 :' + errorMessage + data.body);
}
// Get
return deferred2.promise;
};
方法3：在方法1之后调用方法2
var getRequest = function (query, queryCandidateNotes) {
var deferred = $q.defer();
$.when(getCandidates(query, queryCandidateNotes)).then(function (data) {
alert('Success1:' + data);
$.when(getCandidateNotes(queryCandidateNotes)).then(function (data1) {
deferred.resolve(data);
alert('Success2:' + data1);
});
})
return deferred.promise;
};
return {
getRequest: getRequest
};
}]);
})();
