djq*_*djq 6 javascript png imgur
我正在尝试使用Javascript上传png到imgur.我直接使用了Imgur API 示例中的代码,但我不认为我正在传递png文件,因为我收到一条错误消息file.type is undefined.我认为该文件没问题,因为我尝试了几个不同的png.我的代码如下:
<html>
<head>
<script type="text/javascript">
function upload(file) {
// file is from a <input> tag or from Drag'n Drop
// Is the file an image?
if (!file || !file.type.match(/image.*/)) return;
// It is!
// Let's build a FormData object
var fd = new FormData();
fd.append("image", file); // Append the file
fd.append("key", "mykey"); // Get your own key: http://api.imgur.com/
// Create the XHR (Cross-Domain XHR FTW!!!)
var xhr = new XMLHttpRequest();
xhr.open("POST", "http://api.imgur.com/2/upload.json"); // Boooom!
xhr.onload = function() {
// Big win!
// The URL of the image is:
JSON.parse(xhr.responseText).upload.links.imgur_page;
}
// Ok, I don't handle the errors. An exercice for the reader.
// And now, we send the formdata
xhr.send(fd);
}
</script>
</head>
<body>
<button type="button" onclick="upload('test.png')">upload to imgur</button>
</body>
</html>

该png文件test.png存储在与我的html文件相同的目录中.
