我正在尝试使用与Native api网关的react-native.相同的代码(纯JS)在ios上运行很好,但在 android上它失败了403错误.

var signedRequest={
  "headers": {
    "Content-Type": "application/json","Accept": "application/json","x-amz-date": "20170918T134411Z","Authorization": "AWS4-HMAC-SHA256 Credential=ASIAIBC7RQ7MFUIRO7QQ/20170918/ap-northeast-1/execute-api/aws4_request,SignedHeaders=accept;content-type;host;x-amz-date,Signature=9fb6d4d4820024097f25aaa70648fxxx7a54a2db1a67d173189693dc073d0a0bac8","x-amz-security-token": "AgoGb3JpZ2luEKn////////xxxG1iKJBHjjvZH0DxcSqE889Wb3Mv+8PwMqrRe/O5dFFmP+9bQj+fSwVIUvmBplKkQB62x/xTelGHoCEOPXpBWLjT2OAUaBXOti7UZyfyMNgg56/Z58yxk4o2/37xPLbhXfODaL8kydFV8IaPJjdbJIX+a0kXycPLBnVIBdukUp9cMVD27mWN41u3w0VP5J8YiMPzrDnwKtb0U37naoIaknMBqNBDkMGQyHal/TBJ3wjJvJWVntrJvex0QKD8rDLHjaoiIYjBd+a04m2pKsBQJ9WQl02TTCPgRp0bb1oARF2hz0Xpi45Ba6a6E9SAL07UcRShTwX6rmxi0dZ38mkSbBMjI45Xg8r/VaRZx6/OyCq3u+nq4bgLCOMKqb/80F"
  },"data": "{"data":{"func":"checkIfFacebookSignupComplete","data":{}}}","method": "POST","url": "https://xxx.execute-api.ap-northeast-1.amazonaws.com/dev/user/user"
}

var apiResponse=await fetch(signedRequest.url,{

  method: signedRequest.method,body: signedRequest.data,headers: signedRequest.headers,})
console.log("Got api response : ",apiResponse)

在iOS上它收到一个http响应200.但是,在android上它失败了：

“我们计算的请求签名与您提供的签名不匹配.请检查您的AWS秘密访问密钥和签名方法.有关详细信息,请参阅服务文档.

The Canonical String for this request should have been
'POST
/dev/user/user

accept:application/json
content-type:application/json; charset=utf-8
host:uihw7hnkn7.execute-api.ap-northeast-1.amazonaws.com
x-amz-date:20170918T134411Z

accept;content-type;host;x-amz-date
6b83b80f2875c2425c28b258886ad98603fd802095e35303a3c2a72528374fb5'

The String-to-Sign should have been
'AWS4-HMAC-SHA256
20170918T134411Z
20170918/ap-northeast-1/execute-api/aws4_request
008853cdfba53255257d9169e1a9c05500d01299da9efd4695ac8c66cb31e5e7'
"

我也尝试过axios.同样的结果. (ios工作正常,android失败)我正在使用react-native 0.42.3.

任何人都知道可能是什么问题？

解决方法

经过大量挖掘后,问题似乎与此处描述的相关： https://github.com/facebook/react-native/issues/14445. android okHttp库(反应原生地使用)将charset = utf = 8添加到请求中.因此解决方案是使用标头计算sig4值,如下所示：

var signedRequest={
  "headers": {
    "Content-Type": "pplication/json; charset=utf-8","Authorization": "Calculated sig4 auth","url": "https://xxx.execute-api.ap-northeast-1.amazonaws.com/dev/user/user"
}
