[Solved] Get HTTP error status code

hassansardarlecodeur · March 26, 2020, 6:06pm

How do I get HTTP status code in case of 401?

Here is my code:

var result = HTTP.call("POST", 'http://example.com', { data:{"key": "value"}, headers:{'Content-Type' : 'application/json'}});
console.dir(result );

In case of error i get this exception:

I20200326-22:23:49.080(5)? 'Error: failed [401] {"data":null,"description":"Invalid Password!","status":"ERROR","statusCode":4012}\n' +

How can I get error status code from this?

Wrap it to try{}catch(){} block or use asynchronous version with callback.

try {
  var result = HTTP.call("POST", 'http://example.com', { data:{"key": "value"}, headers:{'Content-Type' : 'application/json'}});
  console.dir(result);
} catch (error) {
  console.log(error);
}

hassansardarlecodeur · March 26, 2020, 9:10pm

@dr.dimitru This is what I get in catch too. Its the same for asynchronous too

dr.dimitru · March 26, 2020, 9:21pm

What exactly are you trying to accomplish? What’s your goal?

hassansardarlecodeur · March 26, 2020, 9:23pm

In case of Error Code 401, I want to apply some logic on the response I received from API. I want to use that response data.

dr.dimitru · March 26, 2020, 9:26pm

Try this:

const processStatusCode = (code) => {
  if (code === 401) {
    // your logic here 
  }
};

try {
  const result = HTTP.call("POST", 'http://example.com', { data:{"key": "value"}, headers:{'Content-Type' : 'application/json'}});
  processStatusCode(result.statusCode);
} catch (error) {
  processStatusCode(error.response.statusCode);
}

hassansardarlecodeur · March 26, 2020, 9:33pm

Its the same. I also want to take some decisions on the response data, not just the error code

dr.dimitru · March 26, 2020, 9:35pm

Well, update and adapt the code I’ve posted to meet your needs.

hassansardarlecodeur · March 26, 2020, 9:36pm

But its not working bro. I am getting the same error.

dr.dimitru · March 26, 2020, 9:37pm

Exception or error?
Exception or error?

hassansardarlecodeur · March 26, 2020, 9:38pm

Exception:

'Error: failed [401] {"data":null,"description":"Invalid Password!","status":"ERROR","statusCode":4012}\n' +

hassansardarlecodeur · March 26, 2020, 9:40pm

FYI, error.statusCode is undefined in catch

dr.dimitru · March 26, 2020, 9:40pm

Is it thrown even being inside try…catch… block?
And even if callback is passed?
On server?

dr.dimitru · March 26, 2020, 9:42pm

What if you console.log(error)?

hassansardarlecodeur · March 26, 2020, 9:49pm

Ok here is the complete scenario:

Code:

try {
  
    var result = HTTP.call("POST", srcUrl, { data:postFields, headers:headersData });

    console.log('-- In Try --');
    console.dir(result);
}
catch (error) {

    console.log('-- In Catch --');
    console.log(error);
    console.log(error.statusCode);
}

Result:

I20200327-02:46:56.570(5)? -- In Catch --
I20200327-02:46:56.572(5)? Error: failed [401] {"data":null,"description":"Invalid Password!","status":"ERROR","statusCode":4012}

So it isn’t throwing exception, it’s caught error.

Updated:

const processStatusCode = (code) => {
  if (code === 401) {
    // your logic here 
  }
};

try {
  const result = HTTP.call("POST", 'http://example.com', { data:{"key": "value"}, headers:{'Content-Type' : 'application/json'}});
  processStatusCode(result.statusCode);
} catch (error) {
  processStatusCode(error.response.statusCode);
}

Nice. It worked like a charm. Thanks for the help bro,
