[英]Not able to fetch data from particular list item of site content using React APP WEB-part
我能夠獲取我們在站點內容的登陸屏幕上看到的列表。 但是,當我嘗試通過按標題查找特定項目來獲取數據時,我在 URL 中出現錯誤 CANNOT FIND LIST 'EmployeeList'。
我已經構建了一個 React Web 部件,這里是文件和代碼
ListOfSprintStories.tsx
private _getListData(): Promise<ISPLists> {
return this.props.context.spHttpClient.get(this.props.context.pageContext.web.absoluteUrl + `/_api/web/lists/GetByTitle('EmployeeList')/Items`, SPHttpClient.configurations.v1)
.then((response: SPHttpClientResponse) => {
return response.json();
});
}
private _renderListAsync(): void {
// Local environment
if (Environment.type === EnvironmentType.Local) {
this._getMockListData().then((response) => {
this.setState({ finalList: response.value });
});
}
else if (Environment.type == EnvironmentType.SharePoint ||
Environment.type == EnvironmentType.ClassicSharePoint) {
this._getListData()
.then((response) => {
console.log('======>', response.value)
this.setState({ finalList: response.value });
});
}
}
componentDidMount() {
this._renderListAsync()
}
IListOfSprintStoriesProps.ts
import { WebPartContext } from '@microsoft/sp-webpart-base';
export interface IListOfSprintStoriesProps {
description: string;
context: WebPartContext;
}
ListOfSprintStoriesWebPart.ts
import * as React from 'react';
import * as ReactDom from 'react-dom';
import { Version } from '@microsoft/sp-core-library';
import {
IPropertyPaneConfiguration,
PropertyPaneTextField
} from '@microsoft/sp-property-pane';
import { BaseClientSideWebPart } from '@microsoft/sp-webpart-base';
import * as strings from 'ListOfSprintStoriesWebPartStrings';
import ListOfSprintStories from './components/ListOfSprintStories';
import { IListOfSprintStoriesProps } from './components/IListOfSprintStoriesProps';
import { WebPartContext } from '@microsoft/sp-webpart-base';
export interface IListOfSprintStoriesWebPartProps {
description: string;
context: WebPartContext;
}
export default class ListOfSprintStoriesWebPart extends BaseClientSideWebPart<IListOfSprintStoriesWebPartProps> {
public render(): void {
const element: React.ReactElement<IListOfSprintStoriesProps> = React.createElement(
ListOfSprintStories,
{
description: this.properties.description,
context: this.context
}
);
ReactDom.render(element, this.domElement);
}
protected onDispose(): void {
ReactDom.unmountComponentAtNode(this.domElement);
}
protected get dataVersion(): Version {
return Version.parse('1.0');
}
protected getPropertyPaneConfiguration(): IPropertyPaneConfiguration {
return {
pages: [
{
header: {
description: strings.PropertyPaneDescription
},
groups: [
{
groupName: strings.BasicGroupName,
groupFields: [
PropertyPaneTextField('description', {
label: strings.DescriptionFieldLabel
})
]
}
]
}
]
};
}
}
我已按照文檔進行操作。
https://docs.microsoft.com/en-us/sharepoint/dev/spfx/web-parts/get-started/connect-to-sharepoint
我能夠獲取完整的站點內容列表(文檔庫),但是當我嘗試使用 getByTitle('EmployeeList') 獲取特定列表時,它失敗了。
這是錯誤消息:
{"error":{"code":"-1, System.ArgumentException","message":"List 'EmployeeList' does not exist at site with URL 'https://myTenant.sharepoint.com'."}}
請指教。
已修復的問題:通過從 _getMockListData 獲取數據,WebPart 在本地運行良好。
但是,不是當我嘗試在https://MyOffice365.sharepoint.com/sites/**InCorrectSPSite**/_layouts/15/workbench.aspx上測試 WebPart 時
后來我注意到我指向了錯誤的 SP 站點。
