Considering this url: http://example.com/users/1/post/2/likes.
How can I correctly define structure of my 404 response, showing which item is not found? user, post or likes?
You can send an HTTP status code using the header() function, by starting the header with the status code number, followed by the message to send to the user.
header("404 " + $message);
The code that processes the parameters can determine which item isn't found, and put that into $message.

my requirement is to sent the error http status and error message in the body.
In Case of error in flow i need to pass the http code in the status field.
I can configure this http listner but don't know how to set this to get into payload. Please guide on that.
I'm expecting the MEL to get the 400 Bad Request
{
'status': "400 Bad Request",
'message': error.description
}
I could think of 2 ways of doing this:
1.You can use RAML and for every status code you can send appropriate responses as per your use case.This I think is the best way of doing it.
2.You can have the value for status and message key of your response body inside error handling block.Configure the 'TYPE' condition of your error handling block to catch a certain HTTP error message , then inside that you can set 2 vars: one with the status value and other with message value.Then use this vars in the Error response section of HTTP listener. You'll be ending up with many such error handling blocks if you want to address multiple status codes.
Let me know if you need further clarifications.Hope it helps.
Say for example, I created a flow for scatter-gather and I want to check if all endpoints are returning same result status code 200 or throw an error if not.
Configure the Response Validator (General > Response > Response Validator) for each HTTP Request so only 200..299 responses are considered valid.
You can use try block for every HTTP request on wrap whole scatter gather. If one fails, capture HTTP status code in on error propogate and log the results.
I suggest you wrap each request into try block, if you already have a global error handler defined, it should pick up status code 500 etc. Otherwise, capture response code into dataweave
We have implemented an error handler for Yii 1. Also we have implemented the mail functionality with this as any error occurred an email will be send to us but the problem is we are not getting the current URL on which error is generating. Like one page controller/action can contain many images favicons etc. So if any image is missing then we are getting the image URL which showing 404 from:
$url = Yii::app()->createAbsoluteUrl(Yii::app()->request->url);
But we are not getting current URL not even in $error = Yii::app()->errorHandler->error.
So we are not getting the page in which image is absent. Please let me know if is there any way to get current page URL as I have tried many ways but all they are returning the missing images URL instead of main page URL for which images are missing.
createAbsoluteUrl() expects route as first argument - it may return random results if you provide URL instead of route (like in your code snippet).
If you want absolute URL of current request, you may use combination of getUrl() and getHostInfo():
$url = Yii::app()->request->getHostInfo() . Yii::app()->request->getUrl();
In case of error you can get current page url using Yii::app()->request->requestUri in Yii 1.
I'm testing a GET request using Jmeter, this request has path parameter:
rest/V1/autobusca/marketplace/product/:productSku
I'm trying to send the parameter in two different locations
Send Parameters With the Request
And I insert a "User Parameters" as productSku and the value.
I noticed the code response is 200, but the body response is "[]", but when I send it using Postman the response body has a lot of information.
If I change the path in the request like this:
rest/V1/autobusca/marketplace/product/${productSku}
I noticed the code response is 404. Can you help me?
Use "//" instead of "/".
Correct URL will be : rest/V1/autobusca/marketplace/product//${productSku}
I am using UseStatusCodePages Middleware to show status code pages on my application but it shows plain text on UI without any other information,
I want to show UI with Status Code Information along with some other helpful information like Customer Support Number with more user-friendly page.
I found out we can use two extension methods to do that which is UseStatusCodePagesWithRedirects and UseStatusCodePagesWithReExecute. Only Difference I found out from Microsoft Docs is,
UseStatusCodePagesWithRedirects : Send 302 to Client.
UseStatusCodePagesWithReExecute : Send Original Status Code and Executes handler for redirect URL.
Is that the only difference?
I think that the main difference is that UseStatusCodePagesWithRedirects is redirecting you to error controller action method while UseStatusCodePagesWithReExecute is just rendering page with out redirecting
Example
Controller actions
[Route("error/404")]
public IActionResult Error404(int code)
{
return View("Error404");
}
[Route("error/{code}")]
public IActionResult Error(int code)
{
return StatusCode(code);
}
Startup Cinfigue
app.UseStatusCodePagesWithRedirects("/error/{0}");
or
app.UseStatusCodePagesWithReExecute("/error/{0}");
Case 1 (404 Error)
Url : https://localhost:5001/notexits_page
1) UseStatusCodePagesWithRedirects
Result:
Url is: https://localhost:5001/error/404
We see Error404 page
2) UseStatusCodePagesWithReExecute
Result:
Url is: https://localhost:5001/notexits_page
We see Error404 page
Case2 (401 Error)
Url : https://localhost:5001/admin/users
1) UseStatusCodePagesWithRedirects
Result:
Url is: https://localhost:5001/error/401
We stack in infinity loop
1) UseStatusCodePagesWithRedirects
Result:
Url is: https://localhost:5001/admin/users
We see default browser error page for 401 error
When Using app.UseStatusCodePagesWithRedirects("/Error/{0}") and invalid request(lets say "/abc/xyz") is raised then;
Status Code 404 is issued, app.UseStatusCodePagesWithRedirects("/Error/{0}") intercepts the request and 302 status code is issued(which means URI of the requested resource has been changed temporarily)
As 302 is issued another get request is issued which results in change of the url from
"/abc/xyz" to "/Error/404".
As the request is redirected to the specific error controller the status code for the request is 200 ok in the browser developer tool.
But When Using app.UseStatusCodePagesWithReExecute("/Error/{0}") and invalid request(lets say "/abc/xyz") is raised then;
app.UseStatusCodePagesWithReExecute("/Error/{0}") middleware intercepts the 404 status code and re-executes the pipeline pointing it to the URL
As the middleware is re executing the pipeline the original URL "/abc/xyz" in the address bar is preserved. It does not change from "/abc/xyz" to "/Error/{0}".
Also the original status Code(404 in this case) is preserved in the developer tool.
