使用APIG触发器调用一个返回String的FunctionGraph函数,报500错误,该如何解决?
FunctionGraph函数对来自APIG调用的返回结果进行了封装,APIG触发器要求函数的返回结果中必须包含body(String)、statusCode(int)、headers(Map)和isBase64Encoded(boolean),才可以正确返回。
Node.js函数APIG触发器调用返回结果定义示例如下:
exports.handler = function (event, context, callback) { const response = { 'statusCode': 200, 'isBase64Encoded': false, 'headers': { "Content-type": "application/json" }, 'body': 'Hello, FunctionGraph with APIG', } callback(null, response); }
Java函数APIG触发器调用返回结果定义示例如下:
import java.util.Map; public HttpTriggerResponse index(String event, Context context){ String body = "<html><title>FunctionStage</title>" + "<h1>This is a simple APIG trigger test</h1><br>" + "<h2>This is a simple APIG trigger test</h2><br>" + "<h3>This is a simple APIG trigger test</h3>" + "</html>"; int code = 200; boolean isBase64 = false; Map<String, String> headers = new HashMap<String, String>(); headers.put("Content-Type", "text/html; charset=utf-8"); return new HttpTriggerResponse(body, headers, code, isBase64); } class HttpTriggerResponse { private String body; private Map<String, String> headers; private int statusCode; private boolean isBase64Encoded; public HttpTriggerResponse(String body, Map<String,String> headers, int statusCode, boolean isBase64Encoded){ this.body = body; this.headers = headers; this.statusCode = statusCode; this.isBase64Encoded = isBase64Encoded; } }
