How to detect end of _find in CouchDB? - bash

Using CouchDB (3.1.1 on windows) I want to iterate on the results of a /db/_find using the bookmark mechanism.
It works pretty well, but I don't know how to end the looping. The code is similar to this:
while true
do
curl -s -X POST $dburl/db/_find -H "Content-Type: application/json" \
-d '{"selector":{bla bla},"bookmark":'$b'}' > result.dat
Extract bookmark from result.dat and assign it to b variable
done
How to end such loop? The result contains a valid bookmark even when there are no more documents to be returned and curl always succeeds.
Thanks for your help!

Thanks for the suggestion RamblinRose!
Here is the solution that works beautifully:
n=200
b=null
while [ $n = 200 ]
do
x=`curl -s -X POST $db/kb/_find -H "Content-Type: application/json" \
-d '{"selector": {bla bla},"limit":200,"bookmark":'$b'}' | tee -a $tmp | jq '.bookmark,(.docs | length)'`
a=($x)
b=${a[0]}
n=${a[1]}
done

Curl for loop issue

for a in {P02183606,P02183608}
do
for b in {PID,PID2}
do
curl -i -H "Authorization:Token sample" "Content-type: application/json" -X GET "http://mastindia//project/push?applicationRefNo=$a&applicationFormId=$b"
done;
done;
Expected Output
Service should call 2 times not 4 times.(Issue is only $a and $ b values should be below)
http://applicationRefNo=P02183606&applicationFormId=PID
http://applicationRefNo=P02183608&applicationFormId=PID2
A nested for loop will always run n*n2 times.
In your case, there is no need to nest the loop, you can just do it like this:
#bin/bash
whatever=("P02183606" "PID" "P02183608" "PID2");
for((i = 0; i<${#whatever[#]}; i=i+2));
do
curl -i -H "Authorization:Token dont share it ffs" "Content-type: application/json" -X GET "http://indiafirstlife.com//onlineInsurance-rest/uploadDocument/uploadDocumentsOmniMannualPush?applicationRefNo=${whatever[i]}&applicationFormId=${whatever[i+1]}"
echo "Accessing: http://indiafirstlife.com/onlineInsurance-rest/uploadDocument/uploadDocumentsOmniMannualPush?applicationRefNo=${whatever[i]}&applicationFormId=${whatever[i+1]}"
done
Output:
Accessing: http://indiafirstlife.com/onlineInsurance-rest/uploadDocument/uploadDocumentsOmniMannualPush?applicationRefNo=P02183606&applicationFormId=PID
Accessing: http://indiafirstlife.com/onlineInsurance-rest/uploadDocument/uploadDocumentsOmniMannualPush?applicationRefNo=P02183608&applicationFormId=PID2

Running Curl POST w/ JSON Payload Sequentially Against File

I am hitting a wall trying to build a script to save myself quite a good bit of time. I am working in a system in which I need to run a curl POST against a list of values. The list is about 400 lines long, so I am hoping to find a way of scripting this in Bash instead of running that call manually for each entry. Below are some details to help understand what I'm trying to accomplish:
If I were to be doing this task manually, each call would be formatted like the below:
curl -X POST --header "Content-Type: application/json" -v 'http://www.website.com:8081/cc/membership' -d #json_payload.json
This points to my JSON in the listed file which shows as the below:
{
"groupId": "12345678987654321",
"type": "serial",
"memberInfo": "apple"
}
If I run the above, the call works, and the expected operation occurs. The issue is that I need to run this against roughly 400 values for that "memberInfo" field in the JSON payload. I'm trying to identify a way to run a single bash script, which will run this curl command over and over, and update the JSON payload to use each row in a file as the below:
memberList.txt
apple
banana
peach
pear
orange
.
.
And then maybe insert a pointer in my JSON for the "memberInfo" field over to this file.
Any and all help/suggestions are greatly appreciated!
.
This will do as you intend. Its a little convoluted but you might polish it a bit.
#!/bin/bash
function getString(){
echo $1 | python3 -c '
import json
import sys
payload="""
{
"groupId": "12345678987654321",
"type": "serial",
"memberInfo": ""
}
"""
obj = json.loads(payload)
obj["memberInfo"] = sys.stdin.read().strip()
print(json.dumps(obj, indent = " "))
'
}
while read member
do
getString "$member" > json_payload.json
curl -X POST --header "Content-Type: application/json" -v 'http://www.website.com:8081/cc/membership' -d #json_payload.json
done <<< "$( cat fruits.txt )"
Hope it helps!
while read member; do
curl -X POST --header "Content-Type: application/json" -v 'http://www.website.com:8081/cc/membership' -d '{"groupId": "12345678987654321","type": "serial","memberInfo": "$member"}'
done <members.txt
This will work if you only care about the memberInfo field, another method could be writing your json line by line to payloads.txt file.
payloads.txt
{"groupId": "12345678987455432","type": "stereo","memberInfo": "apple"}
{"groupId": "34532453453453465","type": "serial","memberInfo": "banana"}
...
then use this as the script
while read payload; do
curl -X POST --header "Content-Type: application/json" -v 'http://www.website.com:8081/cc/membership' -d '$payload'
done <payloads.txt

Loop through list for curl requests in bash

I have a bash script that sends a curl request and displays the response.
#!/bin/bash
token=$(curl -k -X GET \
'https://v.mytesting.io/oauth/token?grant_type=password&username=user1&password=123' \
-H 'Authorization: Basic 12345678' \
-H 'Host: v.mytesting.io.io')
v=$( jq -r ".access_token" <<<"$token" )
ts=$(curl -k -X POST \
https://timeseries.mytimeseries.io/v5/time_series/query \
-H 'Authorization: Bearer '"$v" \
-H 'Content-Type: application/json' \
-H 'Host: timeseries.mytimeseries.io' \
-H 'tenant: 123-123-123' \
-d '{"operation" : "raw","responseFormat" : "kairosDB","startTime": "1d-ago","stopTime": "now","tagList" : [ {"tagId" : "V.S.23164117.AVG.10M"}]}')
p=$(jq '.queries[].sample_size, .queries[].results[].name' <<<"$ts")
echo "$p"
My current output is just a value and the name of the tagId.
My query only allows for 1 tagId ( you can see above )
I want to be able to set a list of tagId's.
Then when I run this script it should loop through the list of tagId's and execute the curl request replacing the V.S.23164117.AVG.10M with each value
in the list.
Then output the entire list of results into a file.
list would be like so - (I would love to be able to enter this list into a seperate file and the bash script calls that file. Sometimes this list can be a few hundred lines.
V.S.23164117.AVG.10M
V.S.23164118.AVG.10M
V.S.23164119.AVG.10M
V.S.23164115.AVG.10M
V.S.23164114.AVG.10M
output would like look so.
value tagId
value tagId
value tagId
100 V.S.23164117.AVG.10M
etc..
thank you for any help
You can loop over list of tags using a small script. I'm not 100% clean of the output format. You can change the 'echo' to match the required format.
Note minor change to quotes to allow variable expansion in the body.
The tags will be stored in a file, for examples, tags.txt
V.S.23164117.AVG.10M
V.S.23164118.AVG.10M
V.S.23164119.AVG.10M
And the script will be use the file
#! /bin/bash
# Use user defined list of tags
tags=tags.txt
token=$(curl -k -X GET \
'https://v.mytesting.io/oauth/token?grant_type=password&username=user1&password=123' \
-H 'Authorization: Basic 12345678' \
-H 'Host: v.mytesting.io.io')
v=$( jq -r ".access_token" <<<"$token" )
for tag in $(<$tags) ; do
ts=$(curl -k -X POST \
https://timeseries.mytimeseries.io/v5/time_series/query \
-H 'Authorization: Bearer '"$v" \
-H 'Content-Type: application/json' \
-H 'Host: timeseries.mytimeseries.io' \
-H 'tenant: 123-123-123' \
-d '{"operation" : "raw","responseFormat" : "kairosDB","startTime": "1d-ago","stopTime": "now","tagList" : [ {"tagId" : "'"$tag"'"}]}')
p=$(jq '.queries[].sample_size, .queries[].results[].name' <<<"$ts")
echo "$tag $p"
done

Replacing IP in curl command with bash variable

I'm currently trying to make a DDNS script that interacts with the Cloudflare API to catch changes in my ip address and automatically fix the ip address change for my web server. Everything is working correctly so far except I can't get $IP to be put properly in the curl statement. I first run a python script from within the bash script to get the ip address, then run the curl statement in the bash script. Here's what the python script looks like (it returns an ip address like "1.1.1.1" with quotations included because the curl command requires the quotations)
#!/usr/bin/python3
import subprocess as sp
def main():
command = "dig +short myip.opendns.com #resolver1.opendns.com";
ip = sp.check_output(command, shell=True).decode('utf-8').strip('\n');
ip_tmp = ip;
ip_tmp = '"' + ip + '"';
ip = ip_tmp;
print(ip);
if __name__ == "__main__":
main();
And the bash script looks like this:
#!/bin/bash
IP=$("./getIP.py")
curl -X PUT "https://api.cloudflare.com/client/v4/zones/zone_id/dns_records/dns_id" \
-H "X-Auth-Email: example.com" \
-H "X-Auth-Key: authkey" \
-H "Content-Type: application/json" \
--data '{"type":"A","name":"example.com","content":$IP,"ttl":120,"proxied":true}'
I've tried to have the python script only return numbers and then added the quotations in the bash script and now vice versa and I can't seem to get it to work. The last line should end up looking like this once the variable replaces with quotations around the ip address:
'{"type":"A","name":"example.com","content":"127.0.0.1","ttl":120,"proxied":true}'
The single quotes around your json structure prevent the variable from expanding.
You have a few options that are readily available.
Ugly quote escaping inside/around your json.
"{\"type\":\"A\",\"name\":\"example.com\",\"content\":$IP,\"ttl\":120,\"proxied\":true}"
Having the python write this data to a file and telling curl to use that file for the source of the post data.
curl -X PUT "https://api.cloudflare.com/client/v4/zones/zone_id/dns_records/dns_id" \
-H "X-Auth-Email: example.com" \
-H "X-Auth-Key: authkey" \
-H "Content-Type: application/json" \
--data #file_you_wrote_your_json_to.json
Using the python requests or urllib modules to issue the request to cloud flare.
Update your main() function to return the IP instead of print it.
my_ip = main()
url = "https://api.cloudflare.com/client/v4/zones/zone_id/dns_records/dns_id"
myheaders = {
"X-Auth-Email": "example.com",
"X-Auth-Key": "authkey",
"Content-Type": "application/json"
}
myjson = {
"type":"A",
"name":"example.com",
"content":my_ip,
"ttl":120,
"proxied":true
}
requests.put(url, headers=myheaders, data=myjson)
Better yet, just do it in bash. Cloudflare DDNS on github.
One shot to fetch the dynamic A-record ID:
curl -X GET "https://api.cloudflare.com/client/v4/zones/**Zone ID** \
/dns_records?type=A&name=dynamic" \
-H "Host: api.cloudflare.com" \
-H "User-Agent: ddclient/3.9.0" \
-H "Connection: close" \
-H "X-Auth-Email: example#example.com" \
-H "X-Auth-Key: "**Authorization key**" \
-H "Content-Type: application/json"
Cron job (* * * * *) to set the dynamic A-record:
#/usr/bin/env sh
AUTH_EMAIL=example#example.com
AUTH_KEY=** CF Authorization key **
ZONE_ID=** CF Zone ID **
A_RECORD_NAME="dynamic"
A_RECORD_ID=** CF A-record ID from cloudflare-dns-id.sh **
IP_RECORD="/tmp/ip-record"
RECORDED_IP=`cat $IP_RECORD`
PUBLIC_IP=$(curl --silent https://api.ipify.org) || exit 1
if [ "$PUBLIC_IP" = "$RECORDED_IP" ]; then
exit 0
fi
echo $PUBLIC_IP > $IP_RECORD
RECORD=$(cat <<EOF
{ "type": "A",
"name": "$A_RECORD_NAME",
"content": "$PUBLIC_IP",
"ttl": 180,
"proxied": false }
EOF
)
curl "https://api.cloudflare.com/client/v4/zones/$ZONE_ID \
/dns_records/$A_RECORD_ID" \
-X PUT \
-H "Content-Type: application/json" \
-H "X-Auth-Email: $AUTH_EMAIL" \
-H "X-Auth-Key: $AUTH_KEY" \
-d "$RECORD"

"Invalid credentials" while doing a curl POST

I have a curl request in below format
curl -v -H "Content-Type:application/json" -H "x-user-id:xxx" -H "x-api-key:yyy" --data '{"logs":"'"${TEST_OUTPUT}"'","pass":"true | false"}' https://razeedash.one.qqq.cloud.com/api/v1/clusters/zzz/api/test_results
This works fine while I do from my MAC terminal. But the same command throws
13:49:26 {
13:49:26 "status": "error",
13:49:26 "message": "Invalid credentials"
13:49:26 }
I saw this post but not sure how else would I send a json body without curly braces. I know that we can save it as a file.json and use the file as body.But for some reasons that cannot be implemented in my scenario
In general, you should avoid trying to build JSON using string interpolation. Use a tool like jq to handle any necessary quoting.
jq -n --argson o "$TEST_OUTPUT" '{logs: $o, pass: "true | false"}' |
curl -v -H "Content-Type:application/json" \
-H "x-user-id:xxx" \
-H "x-api-key:yyy" \
--data #- \
https://razeedash.one.qqq.cloud.com/api/v1/clusters/zzz/api/test_results
However, if you can manage to correctly generate your JSON as you are now, you can just replace the jq command with echo:
echo '{"logs": ...' | curl ...
The #- argument to --data says to read from standard input.
