Calling service API: 呼叫服务API:
const json = request('http://localhost:8080/part/findall').then(response => response.json());
Error: 错误:

I am getting the data from server but while assign to json getting that above error. 我正在从服务器获取数据,但同时分配给json则得到上述错误。 Can you please help me where I am doing mistake.
您能在我做错的地方帮我吗?
My response Json: 我对杰森的回应:
[{"id":485,"orderno":"00605164","type":"typeA","description":"description"},{"id":486,"orderno":"00605164","type":"typeB","description":"description"}]
This sounds like a serverside issue and not dojo related. 这听起来像是服务器端问题,与dojo无关。
I reproduced your example with a sample json : 我用示例json复制了您的示例:
const json = request('https://jsonplaceholder.typicode.com/posts/1')
.then(response => response.json());
and the data is fine. 并且数据很好。
Here is the complete example 这是完整的例子
import request from '@dojo/core/request';
import xhr from '@dojo/core/request/providers/xhr';
request.setDefaultProvider(xhr);
const json = request('https://jsonplaceholder.typicode.com/posts/1')
.then(response => response.json())
.then(data => console.log(data));
Although the xhr
is optional (it is the default, I guess) - this is fine in a browser and if you replace xhr
by node
it works fine in Node.js too. 尽管
xhr
是可选的(我猜它是默认值)-在浏览器中很好,如果用node
替换xhr
,在Node.js中也可以正常工作。
How is your Server transferring the JSON - maybe as html ? 您的服务器如何传输JSON(也许是html)? Also: What exactly is your dojo version?
另外:您的dojo版本到底是什么?
More information for request than on https://dojo.io can be found in https://github.com/dojo/core/tree/master/src/request 可以在https://github.com/dojo/core/tree/master/src/request中找到比https://dojo.io上更多的请求信息。
您有一个数组作为响应,请尝试使用response [0] .json()
