<h1>JSONP Example</h1>
JSONP is a method that allows cross-domain server calls. You can read more about
it at the <a href="http://json-jsonp-tutorial.craic.com/index.html">JSON versus JSONP Tutorial</a>.
To see this live, run the server locally and open <a href="http://localhost:3999/index.html">http://localhost:3999/index.html</a> (That is, this page.)
<p>
Server:
<pre>
e.Get("/jsonp", func(c *echo.Context) error {
callback := c.Query("callback")
var content struct {
Response string `json:"response"`
Timestamp time.Time `json:"timestamp"`
Random int `json:"random"`
}
content.Response = "Sent via JSONP"
content.Timestamp = time.Now().UTC()
content.Random = rand.Intn(1000)
return c.JSONP(http.StatusOK, callback, &content)
})
</pre>
</p>
<p>
Client:
<pre>
var url = host_prefix + <span class="highlight">'/jsonp?callback=?';</span>
$.getJSON(url, function(jsonp){
$("#jsonp-response").html(JSON.stringify(jsonp, null, 2));
});
</pre>
<input type="button" class="btn btn-primary btn-lg" id="jsonp-button" value="Get JSONP response">
<pre id='jsonp-response'></pre>
</p>
</div>
</body>
