PHP – How to Convert a Postman Request to cURL

curlphppostman

I am calling my Java webservice (POST request) via Postman in the following manner which works perfectly fine (i.e. I can see my records getting inserted into the database):

And, here's how the contents inside the Headers(1) tab look like:

Instead of calling it via Postman, I have to call the same request in PHP using cURL. I am wondering if there's a way to export this command to a curl command so that I could use it in my PHP code? I have found the opposite approach at many places online where someone is asking to convert a curl based request to Postman but couldn't figure out how to do the opposite.

I found this question for curl to Postman: Simulate a specific CURL in PostMan

You can see the button </> Code icon in right side of the Postman app (attached screenshot).
Press it and you can get your code in many different languages including PHP cURL

PHP – How to Simulate cURL Request Using Postman

When using cURL, the -u option (or --user) is used to supply the credentials for HTTP Basic authentication. This sets the Authorization header to contain the necessary data to authenticate with the server.

_{^{These steps apply to Postman's packaged app. For steps for the legacy app, view this of revision this answer.}}

To use HTTP Basic authentication as you were in your cURL command, click the Authorization tab and enter your credentials. Clicking Update Request will add the necessary Authorization header for you.

To submit the JSON data in the same way that you did with cURL, use a POST request, select raw under the Body tab, and enter your data like so:

Postman's Body tab

To debug this I used Fiddler - a free web debugging proxy.

I used cURL's --proxy option to make it send its requests through Fiddler like so:

curl \
--proxy http://localhost:8888 \
-u foo:bar \
-d "{\"jsonrpc\": \"2.0\", \"method\": \"feed.list\", \"id\": 1}" \
http://localhost

Now that the request goes through Fiddler, I can select it from the session list, and use the "raw" inspector to see the raw request:

Fiddler's "raw" inspector

This shows me that the cURL is making a POST request with HTTP Basic authentication and application/x-www-form-urlencoded content. This type of data normally consists of keys and values, such as foo=bar&hoge=fuga. However, this cURL request is submitting a key without a value. A call to var_dump($_POST) will yield the following:

var_dump output

With a = at the end of the data (like so: {"jsonrpc": "2.0", "method": "feed.list", "id": 1}=) the var_dump will yield the following:

var_dump output

However, it seems that JsonRPC will use file_get_contents('php://input') in your case. This returns the data that was submitted with the request, including a =, if the data ends with it. Because it will try to parse the input data as a JSON string, it will fail if the string ends with a =, because that would be invalid JSON.

Using the FoxyProxy extension for Chrome, I created a proxy configuration for Fiddler (127.0.0.1:8888), which allowed me to easily debug the data being sent by Postman's POST request. Using x-www-form-urlencoded with a key of foo with no value, the data sent was actually foo=, which would result in your JSON string being invalid.

However, using "raw" input will allow for the specified data to be sent without a = being added to the end of it, thus ensuring the data is valid JSON.
