AWS-amplify在请求中包含cognito Authorization标头

Question

我创建了一个AWS移动中心项目,包括Cognito和Cloud逻辑.在我的API网关中,我为授权者设置了Cognito用户池.我使用React native作为我的客户端应用程序.如何将Authorization标头添加到我的API请求中.

const request = {
  body: {
    attr: value
  }
};

API.post(apiName, path, request)
  .then(response => {
  // Add your code here
    console.log(response);
  })
  .catch(error => {
    console.log(error);
  });
};

默认情况下,API模块aws-amplify将尝试sig4签名请求.如果您的授权人类型是,那就太棒了AWS_IAM.

使用Cognito用户池授权程序时,这显然不是您想要的.在这种情况下,您需要在Authorization标头中传递id_token ,而不是sig4签名.

今天,你确实可以传递一个Authorization标题来放大,它将不再用sig4签名覆盖它.

在您的情况下,您只需要将headers对象添加到request对象.例如:

async function callApi() {

    // You may have saved off the JWT somewhere when the user logged in.
    // If not, get the token from aws-amplify:
    const user = await Auth.currentAuthenticatedUser();
    const token = user.signInUserSession.idToken.jwtToken;

    const request = {
        body: {
            attr: "value"
        },
        headers: {
            Authorization: token
        }
    };

    var response = await API.post(apiName, path, request)
        .catch(error => {
            console.log(error);
        });

    document.getElementById('output-container').innerHTML = JSON.stringify(response);
}

使用aws-amplify0.4.1进行测试.
