Bulk POST/PUT API Requests Using POSTMAN Or Any Other Means


Answer :

Never mind I figured out a way to use postman's collection runner to accomplish the same. For those who struggled like the way I did, here is how to use that feature and its even easier to substitute values to your url on the go.

First create a request in Postman:

Below is a screenshot for Example:

enter image description here

Now the requirement is to post the below url: https://someApiPOSTRequest/clientAssign?auth=123|asdf&otherParamsList=123Params&someOtherParams={{VariableFromFile}}&additionalParams=hardcodedOnURL

with values being substituted for {{VariableFromFile}} from the csv file you will need to upload. Your csv should be formatted as below, where the header should have the same variable name used on your url:

enter image description here

Click on the '>' button shown below beside Example folder and click on 'Run' to open the same on Collection runner window of postman:

enter image description here

Once the Collection Runner window opens up, click on select file option to upload your csv file, and the Iterations field is pre-filled with the number of records on the csv file by default. You can change the number and when you do make sure of the number of iterations you want to run as its directly related to number of rows in your uploaded csv.

enter image description here

You can also preview your uploaded csv file:

enter image description here

If you click on Run Example button, the collection runner posts the url 9 times with {{VariableFromFile}} being substituted with value from csv file for each iteration.

You can have more variables substituted by just having one more column with the relevant variable name and using the same on your api call. Its just that simple. It did reduce a lot of manual work for me!!

You can also refer to the below link which guided me to use this feature in Postman. Link

Hope this will be helpful for someone.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
