There are some issues with the <code>curl</code> command here that I would prefer to approach slightly differently.
The first issue is the preparation of the JSON.
With <code>'{&quot;DataArr&quot;:[{&quot;serialno&quot;:'${sNo[i%5]}',&quot;filePath&quot;:'$f'}]}'</code>, the resulting JSON has a problem. The values for <code>serialno</code> and <code>filePath</code> looks likely alphanumeric or may contain spaces, meaning the values would need to be double quoted, eg <code>&quot;filePath&quot;: &quot;/path/to/some where/to/new note&quot;</code>, and this is not handled.
I would suggest to prepare the JSON using <code>jq</code> and store in a shell variable for later use with <code>curl -d</code>. Example,
<pre><code>jq --null-input \
 --arg serialno ${sNo[i%5]} \
 --arg filePath $f \
 '{&quot;DataArr&quot;: [{&quot;serialno&quot;: $serialno,&quot;filePath&quot;: $filePath}]}'
</code></pre>
<code>--null-input</code> is used because we wants to construct JSON data from scratch
<code>--arg name value</code> allows us to pass a string value to <code>jq</code> as a predefined variable.
This will for example gives you the following well formed JSON:
<pre><code>{
 &quot;dataarr&quot;: [
 {
 &quot;serialno&quot;: &quot;ab1&quot;,
 &quot;filepath&quot;: &quot;/home/name/notes1&quot;
 }
 ]
}
</code></pre>
And this well formed JSON can be stored in a shell variable for later use:
<pre><code>prepared_payload=$( jq --null-input \
 --arg serialno ${sNo[i%5]} \
 --arg filePath $f \
 '{&quot;DataArr&quot;: [{&quot;serialno&quot;: $serialno,&quot;filePath&quot;: $filePath}]}' )
</code></pre>
Now we can use this <code>prepared_payload</code>, like <code>curl -d &quot;${prepared_payload}&quot;</code>
The next issue is the inappropriate usage of single and double quotes in <code>curl</code> header options <code>-H &quot;'Content-Type: application/json'&quot;</code> and <code>-H 'Authorization: '$token''</code>
There are related past questions/answers, that can be helpful to take a deeper look at,
<a href="https://stackoverflow.com/questions/6697753/difference-between-single-and-double-quotes-in-bash">Difference between single and double quotes in Bash</a>
<a href="https://www.gnu.org/software/bash/manual/html_node/Single-Quotes.html" rel="nofollow noreferrer">https://www.gnu.org/software/bash/manual/html_node/Single-Quotes.html</a>
<a href="https://www.gnu.org/software/bash/manual/html_node/Double-Quotes.html" rel="nofollow noreferrer">https://www.gnu.org/software/bash/manual/html_node/Double-Quotes.html</a>
The preferred approach would be <code>-H &quot;Content-Type: application/json&quot;</code> and <code>-H &quot;Authorization: $token&quot;</code>
The end <code>curl</code> command would thus looks as follows:
<pre><code>prepared_payload=$( jq --null-input \
 --arg serialno ${sNo[i%5]} \
 --arg filePath $f \
 '{&quot;DataArr&quot;: [{&quot;serialno&quot;: $serialno,&quot;filePath&quot;: $filePath}]}' )

curl -d &quot;${prepared_payload}&quot; -H &quot;Content-Type: application/json&quot; \
 -H &quot;Authorization: $token&quot; \
 http://localhost:8080/create
</code></pre>

I am trying to send a post request using curl command in shell script.
When i run this curl command in terminal, it is working fine.
<pre><code>curl -d '{&quot;DataArr&quot;:[{&quot;serialno&quot;:&quot;ab1&quot;,&quot;filePath&quot;:&quot;/home/name/notes1&quot;}]}' -H 'Content-Type: application/json' -H 'Authorization: tasfdgfdhh...' http://localhost:8081/create 
</code></pre>
The same I am trying to run this as shell script file, it is hitting the server but the data format is not expected. The array bracket is converting as :&quot; or something like :{ . I tried so many times with different possibilities but i do not understand how to prepare correct request. Below is the code and the response at server side.
I am using looping statement to simulate multiple requests,
<pre><code>
code:
#!/bin/bash
echo &quot;hello welcome to testing&quot;;
token=asdghadjakalskl.....

requestNo=10
i=0
sNo=(ab1 ab2 ab3 ab4 ab5)
fn=(notes1 Pictures/crop.jpeg Pictures/cat.jpeg Pictures/mountain.jpg Pictures/magic.jpeg Pictures/tree.jpg)

echo $1

for (( i=0; i&lt; $1;i++ ))
do
 # echo &quot;welcome inside the loop $s&quot;
 
 echo ${sNo[i%5]} ${fn[i%6]}
 f=&quot;/home/name/${fn[i%6]}&quot;
 # echo $token
 echo file $f
 echo $i request sent
 
 curl -d '{&quot;DataArr&quot;:[{&quot;serialno&quot;:'${sNo[i%5]}',&quot;filePath&quot;:'$f'}]}' -H &quot;'Content-Type: application/json'&quot; -H 'Authorization: '$token'' http://localhost:8080/create

 
done
</code></pre>
At server side,
<pre><code>{&quot;{\&quot;qualityDataArr\&quot;:&quot;:{&quot;{\&quot;serialNumberCustomer\&quot;:ab1,\&quot;filePath\&quot;:/home/name/notes1}&quot;:&quot;&quot;}}

</code></pre>
Please guide me.
Thank you!
