使用getfilebyserverrelativeurl或getfolderbyserverrelativeurl时的HTTP 400 Bad Request

Question

我一直在尝试设置基本的CRUD操作示例SharePoint 2013 App.

我有一个开发人员模板站点设置(例如reporting.domain.com/sites/dev).在该网站内,我有一个带有文件的"文档库"应用程序/列表设置.我在清单中给出了"web"写入权限.

我需要的是通过REST API执行基本的CRUD操作.现在我只是尝试获取和删除操作.我收到400"错误请求".我完全陷入困境.想法？

<?xml version=\"1.0\" encoding=\"utf-8\"?>
<m:error xmlns:m=\"http://schemas.microsoft.com/ado/2007/08/dataservices/metadata\">
<m:code>-2147024809, System.ArgumentException</m:code>
<m:message xml:lang=\"en-US\">Value does not fall within the expected range.</m:message>
</m:error>

这是我正在使用的javascript代码.gethostWebTitleAndCreated有效,但getReport或deleteReport都不起作用

(function () {
    'use strict';
    var hostweburl,
        appweburl;

    // Function to retrieve a query string value.
    // For production purposes you may want to use
    //  a library to handle the query string.
    function getQueryStringParameter(paramToRetrieve) {
        var params, i, singleParam;
        params = document.URL.split("?")[1].split("&");

        for (i = 0; i < params.length; i = i + 1) {
            singleParam = params[i].split("=");
            if (singleParam[0] === paramToRetrieve) {
                return singleParam[1];
            }
        }
    }

    function gethostWebTitleAndCreated() {
        var url = appweburl + "/_api/SP.AppContextSite(@target)/web?@target='" + hostweburl + "'" + "&$select=title,created";
        $.ajax(
            {
                url: url,

            }
        );
    }

    function deleteReport() {
        var executor = new SP.RequestExecutor(appweburl);
        executor.executeAsync({

    // Load the required SharePoint libraries
    $(document).ready(function () {

        // resources are in URLs in the form:

Answer 1

端点错误http://<sitecollection>/<site>/_api/web/getFileByServerRelativeUrl(serverRelativeUrl):

Value does not fall within the expected range.

serverRelativeUrl无法找到参数指定的文件时发生.

确保serverRelativeUrl正确指定了文件的参数,使用以下格式:

/<web>/<list>/<folder>/<file>

Answer 2

另一个解决方法（我也很惊讶地发现）是删除/主角。

不工作

http://site url/_api/web/GetFolderByServerRelativeUrl('/Shared Documents')

工作中

http://site url/_api/web/GetFolderByServerRelativeUrl('Shared Documents')
