#Curl json helper how to#
I hope this tutorial has been helpful in showing you how to use `curl` to send a POST request with a JSON body. You can use a tool like JSONLint () to validate your JSON data before sending it in the request.
Keep in mind that the JSON data in the request body must be properly formatted and valid, or the request may fail. 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 an example of using the `-i` option to print the response headers: curl -X POST -H "Content-Type:application/json" -d data.json -iĪnd 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 -o response.txt 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. If the request is successful, the server will return a response. Here’s the command to send the POST request with the JSON data: curl -X POST -H "Content-Type: application/json" -d data.json The -d option specifies the request body, and the symbol tells curl to read the data from a file.
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). Use the curl command to send a POST request with the JSON data.
