Making A Post Request With A Json Payload Using Curl Tecadmin

The curl command line utility is a powerful tool for making HTTP requests. It can be used to send a variety of different HTTP requests, including POST requests with a JSON body. Here’s how you can use curl to send a POST request with a JSON body:

Create a JSON fileCreate a JSON file that contains the data you want to send in the request body. For example, let’s say you have a file named data.json with the following contents: { “name”: “John Doe”, “age”: 25 }1234{  “name”: “John Doe”,  “age”: 25} Curl POST DataUse the curl command to send a POST request with the JSON data. The -X option specifies the request method (in this case, POST), and the -H option adds an HTTP header (in this case, Content-Type: application/json to specify that the request body is in JSON format). The -d option specifies the request body, and the @ symbol tells curl to read the data from a file.Here’s the command to send the POST request with the JSON data:curl -X POST -H “Content-Type: application/json” -d @data.json http://example.com/endpoint Curl POST Data with Response HeaderIf the request is successful, the server will return a response. You can use the -i option to include the response headers in the output, or the -o option to save the response to a file.Here’s an example of using the -i option to print the response headers:curl -X POST -H “Content-Type:application/json” -d @data.json http://example.com/endpoint -i And here’s an example of using the -o option to save the response to a file:curl -X POST -H “Content-Type: application/json” -d @data.json http://example.com/endpoint -o response.txt

That’s all there is to it! With these simple commands, you can use curl to send a POST request with a JSON body to a server.

Here’s the command to send the POST request with the JSON data: Here’s an example of using the -i option to print the response headers: And here’s an example of using the -o option to save the response to a file: Keep in mind that the JSON data in the request body must be properly formatted and valid, or the request may fail. You can use a tool like JSONLint (https://jsonlint.com/) to validate your JSON data before sending it in the request.
