当我使用 GET 方法获取时,我收到错误 502

When I fetch using GET method I receive an error 502

当我尝试使用 GET 获取时收到错误 502,但是当我使用 POST 获取时收到响应。

拉姆达:

const headers = {'Content-Type':'application/json'}


exports.handler = async function(event) {
    return {
      statusCode: 200,
      headers: {
        headers
      },
      body: JSON.stringify({"ok":"ok"})
    }
};

获取:

fetch("https://n3bvznv385.execute-api.us-east-2.amazonaws.com/dev/juegos", {
            method: 'GET',
            headers: {
                'Content-Type': 'application/json',
                'Accept': 'application/json',
                'authorizationToken' : '123',
            }
        }).then(response => response.json())
            .catch(error => console.error('Error:', error))
            .then(response => console.log(JSON.parse(response.body)));

Error using GET Success using POST

API 使用代理集成时来自 Lambda 的网关 expects the following response format

{
    "isBase64Encoded": true|false,
    "statusCode": httpStatusCode,
    "headers": { "headerName": "headerValue", ... },
    "multiValueHeaders": { "headerName": ["headerValue", "headerValue2", ...], ... },
    "body": "..."
}

但是,您将嵌套的 object 作为 headers 传递,因为您的代码解析为:

headers: { {'Content-Type':'application/json'} }.

尝试像这样包含可能的 headers:

exports.handler = async function(event) {
    return {
      statusCode: 200,
      headers: headers,
      body: JSON.stringify({"ok":"ok"})
    }
};
