Overview

The cURL to Go (net/http) Converter translates standard cURL commands into native Go code snippets using the standard library's net/http package. It automatically generates the boilerplate code required for http.NewRequest, configures headers, handles request bodies, and formats the output for direct integration into Go applications.

When to use

When migrating API requests tested in the terminal or Postman into a Go backend service.
When writing integration tests or API clients in Go and needing to replicate specific HTTP headers and payloads.
When debugging API integrations by converting raw cURL commands into structured Go net/http code.

How it works

1Paste your raw cURL command into the input text area.
2Configure options to pretty-print the request body or include explanatory code comments.
3Copy the generated Go code snippet containing http.NewRequest, header assignments, and body handling.

Use cases

Converting a POST request with JSON payload and authorization headers into a Go function.
Generating Go boilerplate code for multipart form data uploads defined in cURL.
Translating complex API requests with custom query parameters and user-agents into native Go code.

Examples

1. Convert a POST Request with JSON Payload

Backend Developer

Background

A developer is integrating a third-party payment gateway and has a working cURL command from the gateway's documentation.

Problem

Manually writing the Go boilerplate for http.NewRequest, setting headers, and encoding the JSON body is tedious and error-prone.

How to use

Paste the cURL command containing the JSON payload and authorization header into the input field, check 'Pretty-print body', and copy the generated Go code.

curl -X POST https://api.stripe.com/v1/charges -H "Authorization: Bearer key" -d "amount=2000&currency=usd"

Outcome

A clean Go code snippet using net/http that sets up the POST request, adds the Authorization header, and passes the URL-encoded body.

2. Convert GET Request with Custom Headers

API Integration Engineer

Background

An engineer needs to fetch user data from an internal microservice that requires specific custom headers for tracing and authentication.

Problem

Replicating the exact headers and query parameters in Go's net/http client requires writing multiple lines of header-setting code.

FAQ

Does this tool support third-party Go HTTP libraries like Resty or Gin?

No, this tool specifically generates native Go code using the standard library's net/http package.

How does the converter handle JSON payloads in the cURL command?

It parses the data payload from the cURL command and formats it as a string reader or byte buffer passed to http.NewRequest.

Can I include comments in the generated Go code?

Yes, you can enable the 'Include comments' option to add explanatory comments to the generated code snippet.

What happens to custom headers in the cURL command?

Custom headers specified with -H or --header are converted into req.Header.Set() calls in the Go code.

Does this tool execute the HTTP request?

No, it only generates the Go source code snippet and does not perform any network requests.

curl -H "X-Request-ID: 12345" -H "Accept: application/json" https://api.internal/users?status=active
