本文介绍在使用Amazon SNS发送短信时遇到的SignatureDoesNotMatch错误及其解决方法，包括正确配置Access Key和Secret Key，确保账号拥有相应权限。

在调用亚马逊发送短信接口的时候，发生了这个错误：
报错信息如下：

Exception in thread "main" com.amazonaws.services.sns.model.AmazonSNSException: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details. (Service: AmazonSNS; Status Code: 403; Error Code: SignatureDoesNotMatch; Request ID: 4d64be74-9b3d-51fd-805f-ede5acd4c416)

    at com.amazonaws.services.sns.AmazonSNSClient.publish(AmazonSNSClient.java:1675)

有三种情况会导致如下错误：

1.项目中没有引入亚马逊的 accessKey 与 secretKey
2.引入了错误的 accessKey 与 secretKey
3.引入的 accessKey 与 secretKey 没有所想使用的权限

以我的代码为例：

发短信的核心代码为：

AmazonSNSClientBuilder.standard().withRegion(“us-east-1”).build().publish(xxx,xxx,xxx);

此时就是没有引入任何的 Key 而直接进行发送，所以是失败的：

解决方案：加一个.withCredentials(new ClasspathPropertiesFileCredentialsProvider()
代码如下：

AmazonSNSClientBuilder.standard().withCredentials(new ClasspathPropertiesFileCredentialsProvider()).withRegion("us-east-1").build().publish(xxx,xxx,xxx);

那么又报错了：

 Unable to load AWS credentials from the /AwsCredentials.properties file on the classpath

此时是因为在resources文件夹中没有 AwsCredentials.properties 的文件。
创建该文件，在里面键入内容：

accessKey=你的iam帐号
secretKey=你的iam密码

再次运行如果还报

Unable to load AWS credentials from any provider in the chain

那么可以查看下自己的帐号是否有权限发送短信（其他权限也是一样）。

通知领导或者自己去添加这部分的权限。
