I am learning nest.js and I am having a hard time setting the response headers..
Here is the code snip
#Controller()
export class AppController {
constructor(private readonly appService: AppService) {}
//#get('users')
#Get()
#Header('Content-Type','text/html')
getHello(): string {
console.log('log')
return this.appService.getHello();
}
}
I can see the log in the terminal running.
When I open the network tab in google chrome to verify the headers, I don't see anything.
I am following this tutorial:: https://youtu.be/F_oOtaxb0L8?t=1530 on youtube
I looked for similar issues on the web and found this :: https://github.com/nestjs/azure-func-http/issues/407
I looked at the documentation and I think I am using everything correctly::
https://docs.nestjs.com/controllers#headers
not sure where I am goofing
You are actually doing it correct. It's not related with nestjs. It's because of your browser's devtools.
You can confirm it by running in your terminal curl -v localhost:3000 (If you don't use linux idk, just send a request without your browser and check the headers)
You should see Content-Type: text/html; charset=utf-8 in headers.
You can also disable persist logs and start a new incognito tab and test in the browser tools. For the first response, dev tools should show you the Content-Type header. For some reason it does not show it more than once.
For detailed explanation probably this is a good question to check.

I was hoping one of you could help me out here. I ran out of ideas already.
I have a script with Cypress.io that basically access a website and clicks on a link for LOGIN. I have reduced the code to only access the LOGIN page directly, which was working perfectly for the past 1-2 months, but in the past week I ran the script and it's no longer working.
When it tries to access the URL https://sso.tce.sp.gov.br/cas-server/login it gives the error below.
The most weird thing is that I can access this URL manually from the other non-automated (EDGE, Chrome), but when I try to do it with the Cypress automated browser it doesn't work.
cy.visit() failed trying to load:
https://sso.tce.sp.gov.br/cas-server/login
We attempted to make an http request to this URL but the request
failed without a response.
We received this error at the network level:
Error: Parse Error: Duplicate Content-Length
Common situations why this would fail:
you don't have internet access
you forgot to run / boot your web server
your web server isn't accessible
you have weird network configuration settings on your computer
Apparently it's doesn't look like a proxy thing nor a code thing, do you guys have any idea of what it could be?
Code:
describe('Test', () => {
it('Access AUDESP Website', function () {
Cypress.config('chromeWebSecurity',false);
//cy.visit('https://www.tce.sp.gov.br/audesp')
//cy.get('.menu-superior-itens > [href="https://sso.tce.sp.gov.br/cas-server/login"]').click()
cy.visit('https://sso.tce.sp.gov.br/cas-server/login')
})
})
Any ideas would be very helpful!!
Thank you!
UPDATE:
Guys, I'm still with this error, but I have found out that the website is sending a duplicate header, but cypress is not able to process it. The browser, outside of Cypress, ignores it apparently... any ideas on how to fix it on Cypress?
I'm working on a CLI with OCLIF. In one of the commands, I need to simulate a couple of clicks on a web page (using the WebdriverIO framework for that). Before you're able to reach the desired page, there is a redirect to a page with a login prompt. When I use WebdriverIO methods related to alerts such as browser.getAlertText(), browser.sendAlertText() or browser.acceptAlert, I always get the error no such alert.
As an alternative, I tried to get the URL when I am on the page that shows the login prompt. With the URL, I wanted to do something like browser.url(https://<username>:<password>#<url>) to circumvent the prompt. However, browser.url() returns chrome-error://chromewebdata/ as URL when I'm on that page. I guess because the focus is on the prompt and that doesn't have an URL. I also don't know the URL before I land on that page. When being redirected, a query string parameter containing a token is added to the URL that I need.
A screenshot of the prompt:
Is it possible to handle this scenario with WebdriverIO? And if so, how?
You are on the right track, probably there are some fine-tunings that you need to address to get it working.
First off, regarding the chrome-error://chromewebdata errors, quoting Chrome DOCs:
If you see errors with a location like chrome-error://chromewebdata/
in the error stack, these errors are not from the extension or from
your app - they are usually a sign that Chrome was not able to load
your app.
When you see these errors, first check whether Chrome was able to load
your app. Does Chrome say "This site can't be reached" or something
similar? You must start your own server to run your app. Double-check
that your server is running, and that the url and port are configured
correctly.
A lot of words that sum up to: Chrome couldn't load the URL you used inside the browser.url() command.
I tried myself on The Internet - Basic Auth page. It worked like a charm.
URL without basic auth credentials:
URL WITH basic auth credentials:
Code used:
it('Bypass HTTP basic auth', () => {
browser.url('https://admin:admin#the-internet.herokuapp.com/basic_auth');
browser.waitForReadyState('complete');
const banner = $('div.example p').getText().trim();
expect(banner).to.equal('Congratulations! You must have the proper credentials.');
});
What I'd do is manually go through each step, trying to emulate the same flow in the script you're using. From history I can tell you, I dealt with some HTTP web-apps that required a refresh after issuing the basic auth browser.url() call.
Another way to tackle this is to make use of some custom browser profiles (Firefox | Chrome) . I know I wrote a tutorial on it somewhere on SO, but I'm too lazy to find it. I reference a similar post here.
Short story, manually complete the basic auth flow (logging in with credentials) in an incognito window (as to isolate the configurations). Open chrome://version/ in another tab of that session and store the contents of the Profile Path. That folder in going to keep all your sessions & preserve cookies and other browser data.
Lastly, in your currentCapabilities, update the browser-specific options to start the sessions with a custom profile, via the '--user-data-dir=/path/to/your/custom/profile. It should look something like this:
'goog:chromeOptions': {
args: [
'--user-data-dir=/Users/iamdanchiv/Desktop/scoped_dir18256_17319',
],
}
Good luck!
I am trying to implement MEAN app for which I made node server
app.get("/posts",(req,res)=>{
posts=[{"title":"a","context":"b"},{"title":"c","context":"d"}]
res.send(posts); // tried even with res.status(200).json(posts)
});
when it checked with api tester it works well output snapshot
output snapshot with apitester
when i try to access with angular services
getposts()
{
var url='http://localhost:3000/posts';
this.http.get<post[]>(url).subscribe(data=>this.posts=data);
console.log(this.posts);
return this.posts;
}
when i do console.log(posts) it returning []
can someone please help i am struggling from last 2 days?
As you have not added the screenshot from the Browser's Inspector => Network Tab, I am guessing this answer will help you in case my guess is right.
Try setting the below in your front-end project (Angular in your case):
Try setting the below in your back-end project (Node in your case):
Also, verify your updates as in the below screengrab in the Browser's Inspector (Chrome in my case):
Please Note: - The mentioned response headers have special meaning, so kindly look for more info with a simple Google search. Use these settings during your development phase on localhost.
Is there a way to log the validation results which get populated in the ResponseStatus when you have the ValidationFeature plugin enabled?
From what i can understand, any requests coming in get validated and if the validation passes then it goes to the service. Using request filters i can log the requests coming in however using the response filters i can only log valid requests.
I trying to log all responses especially HttpStatus 400 (Bad request) which is returned as a result of a validation error.
I have also tried to play a bit with the RequestLog plugin but from what i understood what gets logged are only valid request (i.e requests that went to the service).
I hope you understand what i am trying to say.
Look to see how 7digital have customized ServiceStack's Validation Feature to support logging.
Related Features
The new API supports the concept of a ServiceRunner you can override to add your own event and exception hooks you can read about in the wiki.
There is also the built-in Request Logger that lets you expect details of the more recently processed requests.
Create an issue on the GitHub project if you want to see logging in the validation feature.
A quick way to log errors from the ValidationFeature plugin is simply thus:
public override void Configure(Container container)
{
...etc...
Plugins.Add(new RequestLogsFeature() { etc });
Plugins.Add(new ValidationFeature()
{
ErrorResponseFilter = MyValidationError
});
...etc...
}
public object MyValidationError(ValidationResult validationResult, object errorDto)
{
Container.Resolve<IRequestLogger>().Log(null, null, errorDto, TimeSpan.Zero);
return errorDto;
}
However, in my case, I realized that logging validation errors in the service itself is not the proper place; I instead log these errors in the applications that consume the service.
I am mocking my web service using soapUI.
Now, I also want to test fault. For this, the mock service (=soapUI) should return a HTTP 500.
Does anyone know, how soapUI can do this?
thanks
This can be achieved with the following Groovy code:
mockRequest.getHttpResponse().sendError(500)
Create a mock service.
Create a new mock response.
Open the mock response editor (by double clicking it) and click on the exclamation mark symbol which creates a SOAP Fault response.
If you look at the RAW code of the answer, you see a 500 error code. (HTTP/1.1 500 Internal Server Error)
Btw if you have created two reponses, a successful and a fault response, then when using the mock service service, SOAPUI alternates between the two responses.
Right Click on the MockResponse > Show MockResponse Editor Enter.
Look at MockResponse Properties on the left hand side, bottom
Scroll down to search for "Response HTTP-Status" edit the value to 500.
