I have following code called when loading the page:
var resourceRequest = new WLResourceRequest(
"adapters/adapter-name/rest/init/" + timeStamp,
WLResourceRequest.GET
);
However it returns error in my console:
GET http://localhost:10080/project-name/adapters/adapter-name/rest/init/0 404
(Not Found)
While this code works:
function wlEnvInit() {
console.log("CONNECTING 1111");
WL.Client.connect({c
onSuccess: function(){
console.log("CONNECTED 2222");
},
onFailure: function(error) {
console.log("ERROR IN CONNECTION");
console.log(error);
}
});
}
How to troubleshoot this?
Make sure the adapter is really deployed by visiting the console
Make sure that your application is pointing to an IP address of the host machine where the MobileFirst Server is deployed to
Make sure your adapter call is correct
Example calling:
Client side:https://github.com/MobileFirst-Platform-Developer-Center/ResourceRequestCordova/blob/release80/www/js/index.js#L54
Server side: https://github.com/MobileFirst-Platform-Developer-Center/Adapters/blob/release80/JavaAdapter/src/main/java/com/sample/adapter/JavaAdapterResource.java#L25

I'm trying to follow the example for developing a datasource plugin from Grafana. Ultimately I want my plugin to use Oauth, but even with just the basic Grafana datasource proxy example I seem to be having issues.
I have updated my plugin.json, class and constructor.
I have setup this hard coded example.
in plugin.json
{
"path": "grafana",
"url": "https://github.com"
}
],
And a sample testDataSource()
async testDatasource() {
return getBackendSrv()
.datasourceRequest({
url: this.url + '/grafana/grafana',
method: 'GET',
})
.then(response => {
if (response.status === 200) {
return { status: 'success', message: 'Data source is working', title: 'Success' };
} else {
return { status: 'failure', message: 'Data source is not working: ' + response.status, title: 'Failure' };
}
});
}
When I try and save/test this datasource to call that method, I get in the frontend a
HTTP Error Bad Gateway
And in the logs
t=2021-09-17T14:31:22+0000 lvl=eror msg="Data proxy error" logger=data-proxy-log userId=1 orgId=1 uname=admin path=/api/datasources/proxy/9/grafana/grafana remote_addr=172.17.0.1 referer=http://localhost:3000/datasources/edit/9/ error="http: proxy error: http: no Host in request URL"
I would've expected the request to be routed to the datasource proxy and for that to make the request to github but it seems Grafana is making a request to /api/datasources/proxy/9/grafana/grafana and nothing is picking it up?
Looking up my datasource via API, there's nothing listed for URL.
You will need to render this in your ConfigEditor.tsx
<DataSourceHttpSettings
defaultUrl="http://localhost:8080"
dataSourceConfig={options}
onChange={onOptionsChange}
/>
Which will give you the basic form with URL, whitelist, auth options that you see on most plugins. The URL there I guess should match what you have in your routes.
I am running a vue-project on Chromium 72 on Android v4.4.4 and an API is also running on localhost:8225.
So with the click of a button, I am making a post request using Axios to this localhost API in the project.
var axiosConfig = {
method: "post",
url: "http://localhost:8225/info/update",
data: {},
timeout: 3000,
contentType: "application/json",
headers: {
Authorization: "Basic " + btoa(apiUser + ":" + apiPassword),
},
};
return new Promise(function (resolve, reject) {
axios(axiosConfig)
.then(function (response) {
var result = response;
resolve(result);
console.log("Response", response);
})
.catch(function (error) {
console.log("Error", error);
reject(error);
});
});
But the problem is when I click the button it doesn't hit the API method. It gives Error: timeout of 3000ms exceeded and when I removed the timeout and checked the network tab the request remains in a pending state.
I don't think there is a structural error in the code because the same request works from another application running on the device. When the button is clicked the information gets updated.
Also, I tried all the chromium version till v80 same issue exists. So is there any setting that needs to be changed or enabled on Chromium to handle API requests?
UPDATE:
The API gets hit but when I checked the value of the User(username and password) on HttpListenerContext object, it shows null. I have cross-checked multiple times and I believe the request structure is correct. I am not sure if Chromium is putting some restrictions while sending the requests or the problem is with the backend like CORS issue or maybe something else.
I am using scp2 to copy a file to targetPath. config contains host, username, privateKey, path and port.
const client = require('scp2');
export function scpAsync(config, targetPath) {
return new Promise((resolve, reject) => {
client.scp(config, targetPath, err => {
if (!err){
resolve();
} else {
const errorMessage = err;
reject(errorMessage);
}
});
});
}
When doing so I am getting the error:
Error: Timed out while waiting for handshake
I tried to pass also
promptForPass: false
but it did not change anything. Besides that I used debug mode which told me that I am connected to the server and I put a higher setTimeout but then the error is just coming later. I was checking the documentation of scp2 and their GitHub. I use the function like explained there (https://www.npmjs.com/package/scp2) and regarding the error they could fix it with an higher setTimeout (https://github.com/spmjs/node-scp2/issues/107). I tried with a local ftp server, ngrok and ftp on ec2 instance. All with the same problem.
I would be happy to get help. I asked this question also on superuser but did not get an answer:
https://superuser.com/questions/1576964/error-timed-out-while-waiting-for-handshake
I just implemented my first backend file where I fetch some user data, messages and so on.
Now I wanted to include error handling if there is no network available.
I don´t know if I did it right but this was my approach so far:
import axios from 'axios'
const host = process.env.VUE_APP_URL
export default {
person: async function (currentPerson) {
let params = {
currentPerson: localStorage.getItem("person"),
};
if (user) {
params['currentPerson'] = currentPerson;
}
return axios.get(`${host}/api/currentPerson`, {
params: params
})
//catching network errors
.catch (error => {
if (error.response) {
/*
* The request was made and the server responded with a
4xx/5xx error
*/
console.log(error.response.data);
console.log(error.response.status);
console.log(error.response.headers);
} else if (error.request) {
/*
* The request was made but no response was received
*/
console.log(error.request);
} else {
// Something happened in setting up the request and triggered an Error
console.log('Error', error.message);
}
console.log(error)
});
},
In my mounted() function of my main view I fetch the data from my backend file from above:
backend.matches().then(function (response) {
self.contacts = response.data.persons;
});
I tried to check in console if it is working but all I get is the following:
In the catch block I check for
response errors: like 4xx/5xx
request errors: if my network not responding in time
and any other errors
Would this be the right approach to check if a network is available or not? Or does it degrade the user experience when the user checks the error?
My backend file includes more methods.. do I have to write for each method these kind of requests?
In your backend file you don't react whether there is a network connection or not I think.
And only for reference: that is not the backend, but communicates with the backend - the backend is the part of your code what you communicate with, e.g. Laravel code, an API, ...
Try adding the following at the beginning of your catch part:
if (!error.response) {
//network error
console.log('No network connection');
} else if (error.response) {
//the rest of your code
This should print out No network connection in your console.
Run your application, turn off the internet connection and check the console.
These kind of code should always be located in your backend part.
My answer maybe different from your question.
When i create a .net core API with Angular i used three things to check is there network or not?
subscribe to windows's offline/online event
create signalR hub from layout component to API server
API request failed (it means lot of incident, but if 1. or 2. case is true i know what cause 3. case
I am trying to make a simple windows 8 app but I have a problem.
When I try to make a xhr request to a local webserver it fails with the error code: 0x2efd
Sample code:
WinJS.xhr({ url: "http://192.168.0.30" }).then(
function completed(response) {
//var json = JSON.parse(response.responseText);
//var list = new WinJS.Binding.List(json.results);
console.log(response.responseText);
},
function error(error) { console.log(error) },
function progress(progress) { }
);
But when I try a remote IP for instance google.com it works.
What is going wrong?
Did you declare the "private network" capability in your project's application manifest? Double click your application manifest file - It is located under the capabilities tab.
