腾讯API: [https://cloud.tencent.com/document/product/460/9519][https_cloud.tencent.com_document_product_460_9519]

准备

在下面网页中添加图片 [https://console.cloud.tencent.com/ci/bucket][https_console.cloud.tencent.com_ci_bucket]

使用方法:

需要注意的地方：

**1.获取appid,SecretId,SecretKey**

获取地址: [https://console.qcloud.com/capi][https_console.qcloud.com_capi]

**2. 生成 鉴权签名**

生成方法说明: [ https://cloud.tencent.com/document/product/275/3805][https_cloud.tencent.com_document_product_275_3805]

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)

<?php
    
    $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。
