I have a request payload(JSON format) which has an array with 1000 objects and each object has 6 key value pairs out of which 5 I’m reading from the csv file using parameterization and the 6th key has to be a unique date value of a future date for each of the object in the array.
I tried this with time-shift function which works for 1 iteration but I want to execute it for n- number of iterations.
I checked for groovy code for this but I have no knowledge of groovy and have started learning it.
How can I achieve this in JMeter.
Also, on reading time-shift function from HTTP Request Defaults-Parameters or from the Test Plan-User Defined Variables it does not read different date for each object, it duplicates same date of the first variable in each object.
{
“deviceNumber": “XX”,
“array: [
{
“keyValue1: “${value1_ReadFromCSV}”,
"keyValue2”: “${value2_ReadFromCSV}”,
"keyValue3”: “${value3_ReadFromCSV}”,
"keyValue4”: “${value4_ReadFromCSV}”,
"keyValue5”: “${value5_ReadFromCSV}”,
"keyValue6”: "2020-05-23” (Should be dynamically generated)
},
{
“keyValue7: “value7_ReadFromCSV”,
"keyValue8”: "value8_ReadFromCSV",
"keyValue9”: "value9_ReadFromCSV",
"keyValue10”: "value10_ReadFromCSV",
"keyValue11”: "value11_ReadFromCSV",
"keyValue12”: "2020-05-24” (Should be dynamically generated)
},
.
.
.
.
{
“keyValue995: “value995_ReadFromCSV”,
"keyValue996”: "value996_ReadFromCSV",
"keyValue997”: "value997_ReadFromCSV",
"keyValue998”: "value998_ReadFromCSV",
"keyValue999”: "value999_ReadFromCSV",
"keyValue1000”: "2025–12-31” (Should be dynamically generated)
}
]
}
I have got the partial solution to this, by reading the csv file line by line and storing each line into a variable using groovy. However, I don't want to store directly the line into the variable but to create a JSON object like above from each line of csv file with a unique future date for each object which is in the array.
The csv file is : (Note: I have removed column for date column in csv as I no longer need it.)
deviceNumber,keyValue1,keyValue2,keyValue3,keyValue4,keyValue5,keyValue7,keyValue8,keyValue9,keyValue10,keyValue11,keyValue12,keyValue13,keyValue15,keyValue15,keyValue16

Kindly suggest any reference/example to do this.
I provide only generic instructions:
You can dynamically construct request body using JSR223 PreProcessor
You can read CSV file into memory using File.readLines() function
You can build JSON out of the values from the CSV file using JsonBuilder class

I'm working on a GUI using PyQt5 and a QTableWidget containing CheckBoxes items. I populate the table with data from json file and the user can check/uncheck items.
When I want to retrieve data from my QTableWidget items, I get unexpected error due to some characters : \x19. The character in question is ’ which is well displayed elsewhere.
I don't understand the issue as my input json data is utf-8, I use python3 and when I check my data, I see no encoding issue. This error occurs only when calling text() method on QTableWidgetItem.
As I don't see any other way to retrieve data from my items, I'm quite stuck on it.
with open(filepath) as file:
self.data = json.load(file)
for key, value in self.data.items():
print(key, self.data[key])
keyword_box = QTableWidgetItem(key)
I get no error if I use key to compare with other string for example but when I want to retrieve data (no editing was performed by the user, strings didn't change)
items = self.table.selectedItems()
for item in items:
print(item.text())
I get unknown character in my console and if I try to use the value, I get a \x19 character which fails when I use it to compare with keys in my dictionary.
Could this come from a bug in QTableWidgetItem text() method ?
I have this data in one column in postgresql
{
"geometry":{
"status":"Point",
"coordinates":[
-122.421583,
37.795027
]
},
and i using his query
select * from students where data_json LIKE '%status%' ;
Above query return results but this one does not
select * from students where data_json LIKE '%status:%' ;
How can fix that
Of course the 2nd one doesn't find a match, there's no status: text in the value. I think you wanted:
select * from students where data_json LIKE '%"status":%'
... however, like most cases where you attempt text pattern matching on structured data this is in general a terrible idea that will bite you. Just a couple of problem examples:
{
"somekey": "the value is \"status\": true"
}
... where "status": appears as part of the text value and will match even though it shouldn't, and:
{
status : "blah"
}
where status has no quotes and a space between the quotes and colon. As far as JavaScript is concerned this is the same as "status": but it won't match.
If you're trying to find fields within json or extract fields from json, do it with a json parser. PL/V8 may be of interest, or the json libraries available for tools like pl/perl, pl/pythonu, etc. Future PostgreSQL versions will have functions to get a json key by path, test if a json value exists, etc, but 9.2 does not.
At this point you might be thinking "why don't I use regular expressions". Don't go there, you do not want to try to write a full JSON parser in regex. this blog entry is somewhat relevant.
I would like to use cCSVParse http://michael.stapelberg.de/cCSVParse
in my project. I receive csv data from internet and want to parse it and save to core data. cCSVParse seems to be appropriate class of it. But it can only read csv data from file. When I receive data from internet, I wouldn't like to save it to file. Is there any way to use it for parsing data from NSData or NSString?
One approach is to surround the CSV data (one row at a time) with [] chars and parse it with a JSON parser. (But note that this only works if the non-numeric data items are enclosed in quotes.)
Or you can simply use
NSArray* items = [csvRow componentsSeparatedByString:#","];
if the data items aren't enclosed in quotes.
I have JSON string of following format, which need to be parsed in objective-c
[{"image":"<link_to_image>",
"pic-number":"2862",
"n-lines":5,
"default":"[{"line_1":"one!"},
{"line_2":"two"},
{"line_3":"three"},
{"line_4":"four"},
{"line_5":"five"}]"
},
... ]
The length of default array may vary for each item.
Try TouchJSON which is available in:
http://code.google.com/p/touchcode/
And also go through these

Just found the cause of the problem,
Instead
"default":**"**[{"line_1":"one!"},
{"line_2":"two"},
{"line_3":"three"},
{"line_4":"four"},
{"line_5":"five"}]**"**
The JSON string should has following format otherwise the parsing will fail
"default":[{"line_1":"one!"},
{"line_2":"two"},
{"line_3":"three"},
{"line_4":"four"},
{"line_5":"five"}]
