Hi I am trying to make a call to external rest service using httpwebrequest. I am sending some payload with the httpwebrequest. Now I am trying to code the endpoint. I am not able to figure out the how to get the payload that I sent along with httpwebrequest? I may sound stupid but any help would be appreciated.
I figured it out. It is same as making a rest call using any rest client. you can get the payload using "args" parameter.
for example I am sending a Json Object in the payload. Then I can receive it using the following code:
JObject items = args.payload["items"];
Not sure if it helps anybody.

I am submitting a request for data from the Binanance API as follows:
https://api.bscscan.com/api
?module=logs
&action=getLogs
&fromblock=24726622
&toBlock=24726632
&address=0x94084b7a8d80b2c3cc0dccd87cb6ae3cc67d364d
&topic0=0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef
&apikey=JRYDR6FBWRKY5C8NMZJKFB8GEP1QHFQJQT
However, I can't get any data from this URL. I have double-checked, and I know that the parameters are correct.
Here is an example of using Binanace's API, which works well:
https://api.bscscan.com/api
?module=logs
&action=getLogs
&fromBlock=4993830
&toBlock=4993832
&address=0xe561479bebee0e606c19bb1973fc4761613e3c42
&topic0=0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef
&apikey=YourApiKeyToken
Why is that working but mine not working?
I would highly suggest using Postman, which you can use to quickly test requests. I ran your request, with api-key, through Postman and was able to get a 200 response with data. See this screenshot.
Please note I blanked out the api key value. I suggest you do the same in your post unless its fake.
I had to remove the line breaks in the code you pasted. Could this possibly be the issue?
this might be a stupid question but I was unable to find a solution, also no luck with search.
My Node-Red flow gets triggered by a HTTP Input because I want to create a REST Webservice. It works fine so far but I wonder how to verify the content someone send to me.
As I see right now, I can pass any kind of content. There is no verification if the content matches to the content I want as input.
If I set content-type to application/json, it only accepts json data. That's great but I also want to ensure, users can post only a specific json string.
If someone sends data I'm unable to proceed (not the json object I expected), I want to send HTTP 400 as response.
I'm pretty new to Node-Red and also to json. I'm more an old-school programmer using classic webservices and soap. What I'm missing is some kind of WSDL (not sure if it exists when using REST) and some kind of payload validation.
It would be great if someone can point me the way to go.
Best regards
Patrick
There are some nodes available for doing schema validation on JSON objects.
For example, node-red-contrib-json-schema-validator - which uses ajv as the validation engine under the covers. Unfortunately this node doesn't come with much in the way of help. Essentially it lets you provide your schema and if a message fails to validate, it logs an error which can be handled with a Catch node if you want.
I found the issue. It was too bad.
I just forgotten to set HTTP Header content-type to application/json.
node-red-contrib-json-schema-validator works like a charm if content type is set corret
I am trying to write the GET request for the search API. I am writing it like this http://localhost:8280/solr/1.0/search?searchText=abc, but I am getting a 404. If I'll write it as http://localhost:8280/solr/1.0/, I'm able to get the JSON response data.
I wrote it is as /* and getting the response using the URL http://localhost:8280/solr/1.0/.
If I am writing it as /search* I'm not getting the 404 (http://localhost:8280/solr/1.0/search?searchText=abc).
Where am I getting wrong?
enable wirelogs and check what kind of request is sent from AM to Backend. You might be able to find out the reason for this. refer http://mytecheye.blogspot.com/2013/09/wso2-esb-all-about-wire-logs.html to enable and analyze the logs
I am using PostMan as a REST client to test this API method Cisco ACL Analysis API. specifically POST /acl/trace or getAClTracksStd (first go to Policy Analysis)
Here is my PostMan HTTP test call
Does anyone who is familiar with PostMan understand why I am getting this "Request method 'GET' is not supported" error from the server? I am making a POST HTTP request, not GET.(Selected from Drop down menu) It make more sense for me to get a input invalid parameter error or something.
Just to show that the endpoint url works, heres a HTTP test request that works
(same link, host->host API -> GET /host/{startIndex}/{recordsToReturn}
There's two issues that I'm seeing with your REST call. First, the error you're seeing is because the call needs to be preceded by "https://". Second, remove the interface IDs parameter and values. You should get a response with data after making these changes.
Your json looks erronuous (comma after the destIp) - and the server probably always responds with a default confusing error message in this case. (Postman is very well tested and it sends POST).
Does anyone know how to create a proxy service that will handle this sort of thing?
What I'm looking for is a path parameter and a post body being formatted similar to this:
POST www.myurl.com/{123}
Post body:
myId=1&myOtherId=2
I am currently passing in an XML document and I'm doing an insert on the http:relative-URI element in the transport. This seems to work.
I am also currently doing an insert on the http:query-parameters for my post body name/value pairs.
I am inserting these on the outbound variable. When I debug, both are showing up and I'm contacting the REST service. I am getting a 400 -- Bad Request error. This happens when the post body is not configured correctly.
Any ideas how to do this?
If you are just Posting an XML, then while creating Proxy Service, Select Service Type as Any XML.
