I Have a problem with my API

i have an API

with format API routes look like this

localhost:8081/getdate/param1/:param1/param2/:param2

it was successfully when i just use a paramater with string,

but the problem is when parameter should be like this

REG/112/111

it read as an url ,not a param

how i can solve this?

What I have tried:

search := c.Params.ByName("search")
	client := &http.Client{}
	response, err := http.NewRequest(http.MethodGet, companyhelper.GetHisUrl(cmpId)+"/tregistration/search/"+search, nil)
	if err != nil {
		responseJson.JSONResponse(c, http.StatusBadGateway, gin.H{"tregistration": "Gagal Tersambung"}, gin.H{
			"code":    http.StatusBadGateway,
			"message": "Data Not Found Error Gateway",
		})
	}

The problem is in search parameter

I understand you're encountering an issue with API parameters containing special characters like "/". Here's how to solve it:

1. URL-Encode the Parameter:

Before constructing the request URL, encode the "search" parameter value using a URL encoding function:

import "net/url"

searchEncoded := url.QueryEscape(search)
response, err := http.NewRequest(http.MethodGet, companyhelper.GetHisUrl(cmpId)+"/tregistration/search/"+searchEncoded, nil)

2. Adjust the Route Definition (if necessary):

If you have control over the API route definition, consider removing unnecessary slashes or using more flexible path parameters:

// Example: Allow entire path segment as a parameter
router.GET("/getdate/:param1/:param2", func(c *gin.Context) {
    param1 := c.Param("param1")
    param2 := c.Param("param2")
    // ...
})

3. Reconstruct the URL with a URL Builder (optional):

For complex URLs with multiple parameters, use a URL builder library to ensure proper encoding:

import "net/url"

u, err := url.Parse(companyhelper.GetHisUrl(cmpId) + "/tregistration/search/")
if err != nil {
    // Handle error
}
u.RawQuery = url.Values{"search": {search}}.Encode()
finalURL := u.String()
response, err := http.NewRequest(http.MethodGet, finalURL, nil)
