使用apig触发器调用一个返回string的functiongraph函数时，报500错误-j9九游会登录

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 = ""
                  "
"
                  "
this is a simple apig trigger test

"
                  "
this is a simple apig trigger test
"
                  "";
        int code = 200;
        boolean isbase64 = false;
        map headers = new hashmap();
        headers.put("content-type", "text/html; charset=utf-8");
        return new httptriggerresponse(body, headers, code, isbase64);
    }
class httptriggerresponse {
    private string body;
    private map headers;
    private int statuscode;
    private boolean isbase64encoded;
    public httptriggerresponse(string body, map headers, int statuscode, boolean isbase64encoded){
        this.body = body;
        this.headers = headers;
        this.statuscode = statuscode;
        this.isbase64encoded = isbase64encoded;
    }
}
