Baidu map JS development, open a blank, bmapgl is not defined, err_ FILE_ NOT_ FOUND

One 、 Find the problem

On Baidu map open platform — Instance Center , The operation is all right .

• Copy , Replace ak
• Keep locally html file
• open html, The interface is blank
• F12 Open the developer console , Error reporting found
• GET file://api.map.baidu.com/api?type=webgl&v=1.0&ak=**************** net::ERR_FILE_NOT_FOUND
• Uncaught ReferenceError: BMapGL is not defined

Two 、 solve the problem

It's obvious , Script script Can't access , Led to BMapGL Undefined .

I'll take a look at this script carefully src, It's strange at first sight .

    <script src="//api.map.baidu.com/api?type=webgl&v=1.0&ak= Your key "></script>

I'll try // I added https:, And then it's all right ...

The solution is in script Medium src Add... At the front https:

    <script src="https://api.map.baidu.com/api?type=webgl&v=1.0&ak= Your key "></script>

Feel good , Just one button three times （ give the thumbs-up + Focus on + Collection ）~
