准备

使用方法:

function testorc()

{

var data = {

"appid":"123456abc",

"bucket":"test",

"url":"http://test-123456abc.picsh.myqcloud.com/test.jpg",

};

$.ajax({

type: "POST",

beforeSend: function (xhr) {

xhr.setRequestHeader ("Authorization","N2MXuNZg8kGaJqfIRbkRB3JBetphPTEyNTMzMTA1NDgmaz1BS0lEa2ZVQW1FNmRlV0NoMEJPNHZwYkRhcnd1b2NFbWFOVE4mZT0xNTE1MTTMyJnQ9MTUxMjUxOTEzMiZyPTI3MDQ5NDY0NyZ1PSZmPQ==");

},

url: "http://recognition.image.myqcloud.com/ocr/general",

contentType:"application/json",

data:JSON.stringify(data),

success: function(json) {

var data=eval("("+json+")");

alert(data);

}

});

}

需要注意的地方：

1.获取appid,SecretId,SecretKey

2. 生成 鉴权签名

直接使用AJAX的方式来操作的话，经过测试需要使用V1版本的签名算法。只需要把官方的php的demo代码复制下来，简单修改下对应的超时时间即可。

V1版的生成鉴权签名代码：(需要了解 a k e t r f 分别代表什么 ，V2版本介绍里有)

$expired = time() + 2592000;

$current = time();

$secretKey = 'udBYjjjbVGuNemi';

$srcStr='a=123456abc&k=O4vpbDarwuocEmaNTN&e='.$expired.'&t='.$current.'&r=270494647&u=&f=';

$srcStrOnce='a=2011541224&k=AKID2ZkOXFyDRHZRlbPo93SMtzVY79kpAdGP&e=0&t=1427786065&r=270494647&u=123456

&f=442d8ddf-59a5-4dd4-b5f1-e38499fb33b4';

$signStr = base64_encode(hash_hmac('sha1', $srcStr, $secretKey, true).$srcStr);

$signStrOnce=base64_encode(hash_hmac('sha1',$srcStrOnce,$secretKey, true).$srcStrOnce);

echo $signStr."\n";

echo $signStrOnce."\n";

?>

3.在html的head头中添加Authorization的方法

beforeSend: function (xhr) {

xhr.setRequestHeader ("Authorization","N2MXuNZg8kGaJqfIRbkRB3JBetphPTEyNTMzMTA1NDgmaz1BS0lEa2ZVQW1FNmRlV0NoMEJPNHZwYkRhcnd1b2NFbWFOVE4mZT0xNTE1MTExMTMyJnQ9MTUxMjUxOTEzMiZyPTI3MDQ5NDY0NyZ1PSZmPQ==");

},

4.发送的数据格式要根据官方要求来写

具体参考ajax的写法。
