我使用GraphQL-Yoga作为后端。
它返回的错误的格式与文档不匹配。但是我需要他们的翻译。在expected <- tibble(A=c('red','red','red','blue','blue','blue'),
B=c('yes','no','no','no','no','no'),
yes_in_group=c(TRUE, TRUE, TRUE, FALSE, FALSE, FALSE))
actual <- tibble(A=c('red','red','red','blue','blue','blue'),
B=c('yes','no','no','no','no','no'),
yes_in_group=c(TRUE, FALSE, FALSE, FALSE, FALSE, FALSE))
中是否有一个地方可以捕获服务器中的所有错误,并按Notification组件的预期进行处理?

我遇到了环回问题,因为它在错误对象内部而不是直接在响应的message属性中发送错误。我所做的是:
创建自己的httpClient,如用于设置身份验证令牌的文档中所述。
const httpClient = (url, options = {}) => {
// ...
return fetchUtils.fetchJson(url, options);
}
const dataProvider = jsonServerProvider('http://localhost:3000/api', httpClient);
在您的管理组件中:
<Admin dataProvider={dataProvider}>
然后,您需要创建自己的fetchJson实现:
import { HttpError } from 'react-admin';
const fetchJson = async (url, options = {}) => {
const requestHeaders = (options.headers ||
new Headers({
Accept: 'application/json',
})
);
if (!requestHeaders.has('Content-Type') &&
!(options && options.body && options.body instanceof FormData)) {
requestHeaders.set('Content-Type', 'application/json');
}
if (options.user && options.user.authenticated && options.user.token) {
requestHeaders.set('Authorization', options.user.token);
}
const response = await fetch(url, { ...options, headers: requestHeaders })
const text = await response.text()
const o = {
status: response.status,
statusText: response.statusText,
headers: response.headers,
body: text,
};
let status = o.status, statusText = o.statusText, headers = o.headers, body = o.body;
let json;
try {
json = JSON.parse(body);
} catch (e) {
// not json, no big deal
}
if (status < 200 || status >= 300) {
return Promise.reject(new HttpError((json && json.error && json.error.message) || statusText, status, json));
}
return Promise.resolve({ status: status, headers: headers, body: body, json: json });
};
这实际上只是fetchUtils.fetchJson的副本,但请注意:
return Promise.reject(new HttpError((json && json.error && json.error.message) || statusText, status, json));
这是您应该在json响应中设置错误消息的地方。
最后,您只需将fetchUtils.fetchJson更改为您的fetchJson方法:
const httpClient = (url, options = {}) => {
// ...
return fetchJson(url, options); // <--- change this line
}

我的问题是,我没有在DataProvider中正确抛出错误,这是我如何通过react-admin显示HTTP错误:
import { GET_LIST } from "react-admin";
async function providerApi(type, resourceName, params) {
let res;
try {
switch (type) {
case GET_LIST:
res = await MyGetList(resourceName, params);
break;
/* All other methods */
}
return res;
} catch (error) {
const errorMsg = error.toString();
const code = translateErrorMessageToCode(errorMsg);
const errorObj = { status: code, message: errorMsg, json: res };
throw errorObj;
}
}
function translateErrorMessageToCode(errorMsg) {
if (errorMsg.includes('unauthenticated')) {
return 401
}
if (errorMsg.includes('aborted')) {
return 409
}
if (errorMsg.includes('not-found')) {
return 404
}
return 200
}
