从SAPUI5访问Northwind OData服务时出现Access-Control-Allow-Origin错误? [英] Access-Control-Allow-Origin error when accessing Northwind OData service from SAPUI5?
问题描述
我已经在在线编辑器中创建了一个示例SAPUI5应用程序
I have created a sample SAPUI5 application in online editor
I am getting this below error -
> XMLHttpRequest cannot load
> http://services.odata.org/V2/Northwind/Northwind.svc/Products?$format=json.
> No 'Access-Control-Allow-Origin' header is present on the requested
> resource.
有人可以帮助我解决此问题-我了解这是CORS问题，可以通过禁用chrome中的安全性来解决.
Can someone help me in solving this issue - I understand that it is CORS issue which can be solved by disabling the security in chrome.
但是-我不会禁用chrome的安全功能.因此，还有其他方法(可能通过传递一些标头)来解决此问题.
However - I don't to disable the security feature of chrome. So, is there any other way (probably by passing some headers) to solve this issue.
提前感谢您的帮助.

推荐答案
如果仅出于测试目的，以下解决方案应该是最简单的.
If this is just for the purpose of testing, the following solution should be the easiest.
使用添加所需标题的代理服务，例如以下内容: https://github.com/Rob--W/cors-anywhere
Use a proxy service which adds the needed headers, for example the following: https://github.com/Rob--W/cors-anywhere
用法非常简单，只需在OData URL之前添加代理服务的URL:
Usage is really simple, just add the URL of the proxy service before your OData URL:
var uri = "https://cors-anywhere.herokuapp.com/https://services.odata.org/V2/Northwind/Northwind.svc/Products?$format=json";
