How to read custom ajaxParams in Golang http.Request object

php editor Xiaoxin will introduce to you how to read the custom ajaxParams in the Golang http.Request object. In Golang, we often use the http package to handle HTTP requests. When we use AJAX to send requests, sometimes custom parameters are carried in the request. How to read these custom parameters on the server side? This article will give you a detailed answer and provide concise and effective code examples. Don’t miss this tutorial to make your Golang development more convenient!

Question content

We have the following ajaxparams:

var ajaxParams = {
        type: 'POST',
        url: '/golang_endpoint',
        dataType: 'json',
        customParam: 'customParam',
        success: onResponse,
        error: onError,
    };

Is it possible for golang to read custom properties that appear as *http.request objects in associated golang handlers?

Solution

These parameters are used to perform ajax requests, they are not the parameters that actually reach the server. You should pass it as data for the post request like this:

var ajaxparams = {
    type: 'post',
    url: '/golang_endpoint',
    datatype: 'json',
    data: {customparam: 'customparam'},
    success: onresponse,
    error: onerror,
};
$.ajax(ajaxparams);

Then, on the go side, you just process the data as needed, like this:

type MyStruct {
    customParam string `json:"customParam"`
}

func HandlePost(w http.ResponseWriter, r *http.Request) {
    dec := json.NewDecoder(r.Body)
    var ms MyStruct

    err := dec.Decode(&ms)
    if err != nil {
        panic(err)
    }

    fmt.Println(ms.customParam)
}

Assume you want the parameter to be a string. Either way, you can convert it to the type you want.
