kandi X-RAY | JsonPath Summary
JsonPath is a Java implementation of the JSONPath specification. Details about the specification can be found at This implementation is designed to mimic the Java Pattern class and it's lifecycle. A JsonPath expression, specified as a string, must first be compiled into an instance of JsonPath. The resulting instance can then be used to read content from a JSON string. All of the smarts involved in the content reading reside in the JsonPath instance, so content can be read from multiple JSON strings using the same JsonPath instance. Since a JsonPath instance is thread-safe once compiled, multiple threads can use the same shared instance.

QUESTION
I have an AWS Step Functions state machine defined in a json file, in step1 (a lambda task), I saved three parameters in the ResultPath:
ANSWER
Answered 2021-Jun-14 at 16:17As the error message implies, the string you pass to
s3path.$is not valid JSONPath. If you want to pass some static value, you need to name it without.$at the end (simplys3path), otherwise, like in your case, it will be treated and validated as a JSONPath.Static params don't support any kind of string expansion to my knowledge, especially involving JSONPath. I would suggest passing param called
s3BucketNamein addition to year, month and day, and then simply construct S3 URL inside lambda function itself.

QUESTION
I am getting this error which I am not sure what it means:
Type mismatch. Required: session.Expression[Boolean], found: Validation[CheckBuilder[JsonPathCheckType, JsonNode, String] with SaveAs[JsonPathCheckType, JsonNode, String]]
I am trying to retrieve a value called "title" from an API response body for a user's created assessment and save it as "titleSession". Because not every user that is fed into the simulation will have associated created assessments I am trying to make the saving of "titleSession" only occur if there already exists a "title", hence the doIf:
...ANSWER
Answered 2021-Jun-09 at 09:38This is wrong, you can't use doIf there.
You're looking for the optional validation criterion: https://gatling.io/docs/gatling/reference/current/http/check/#validating
QUESTION
Our Security Dept requirement on egress traffic is very strict: Each app inside POD must go through some proxy with mTLS authentication (app-proxy) using dedicated cert for the app. They're suggesting using squid with tunneling to cope with double mTLS (one for proxy and the other one for the specific traffic app-server), but then we forced the app to be ssl-aware. Istio can come in and do the job but using out-of-the-box ISTIO_MUTUAL mode (between istio-proxy and egress gateway) is not the case for us.
So, I've tried using example Configure mutual TLS origination for egress traffic by modifying it a bit as follows (changes marked with #- and #+):
...ANSWER
Answered 2021-Jun-09 at 08:40OK, finally I've solved it. The key point here is the part of DestinationRule spec, which says:
- credentialName -> NOTE: This field is currently applicable only at gateways. Sidecars will continue to use the certificate paths.
So I've modified the following manifests:
client deployment of sleep.yml (to mount certs)

The knative docs describe the following:
To configure DNS for Knative, take the External IP or CNAME from setting up networking, and configure it with your DNS provider as follows
If the networking layer produced an External IP address, then configure a wildcard A record for the domain:
# Here knative.example.com is the domain suffix for your cluster
*.knative.example.com == A 35.233.41.212If the networking layer produced a CNAME, then configure a CNAME record for the domain:
# Here knative.example.com is the domain suffix for your cluster
*.knative.example.com == CNAME a317a278525d111e89f272a164fd35fb-1510370581.eu-central-1.elb.amazonaws.com

The code below is giving be an error I cant really understand

...ANSWER
Answered 2021-Jun-01 at 13:26I think JSONArray doesn't override method equals, and the implementation of equals from Object is called, which simply compares references.
And you create new JSONArray object, passing same arguments, that is the reference to it will be different from the one created by the framework.

Answered 2021-May-31 at 09:42As per PostgreSQL documentation the filter acts as WHERE condition
When defining the path, you can also use one or more filter expressions that work similar to the WHERE clause in SQL. A filter expression begins with a question mark and provides a condition in parentheses:
I managed to achieve what you're looking for using the LATERAL and a LEFT JOIN
QUESTION
I have a JSON document from which I have figured a way of parsing and extracting the values within it using the library of JSON-Path
I have to evaluate rules/expressions using the variables in the parsed JSON.
For example:
{maxAge:25, minAge:20, age:25}
- rule1 : $.maxAge-$.minAge>100 then send alert
- rule2 : $.age<18 then send alert
What libraries are available in Java for the same ?
...ANSWER
Answered 2021-May-25 at 13:47Json Path will only let you parse the JSON file and read the variables within it. You have to use a separate Java library for evaluating the expressions. Take a look at a this post which discuss the same.
Another useful post that I found on purely mathematical expression evaluation is this one.
It would be helpful if you can identify all the operators that will be part of the expression. For ex, Arithmetic Operators ( +, -, /, *. ), Equality and Relational Operators ( =, !=, <, > )
QUESTION
I've got a script with multiple requests sent as resources of a main request. I need to extract value from 1 of the resources requests and pass to another. Since all this requests are executed in parallel I'm looking for an option to suspend execution of one of them until parameter will be extracted.
Here is some part of my request
...ANSWER
Answered 2021-May-27 at 14:24That can't work. resources are by definition asynchronous and executed concurrently so you have no guarantee request_29 completes and you can capture your token before request_34 starts.
You have to execute request_34 sequentially after request_2, out of its resources.

Install JsonPath
You can use JsonPath like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the JsonPath component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
