如何从触发器调用 google 自定义搜索 Web 服务并解析响应以保存在我的 sObject 中

Question

global class CalloutSevicesQuery implements Database.Batchable<sObject>, Database.AllowsCallouts{
    Public String Query;
    Public String ID;
    public string Body;
    global  CalloutSevicesQuery(String QueryID)
    {
        ID = QueryID;
    }

    global Database.QueryLocator start(Database.BatchableContext BC)
    {
           Query='SELECT id, BodyTxt__c,SubjectTxt__c FROM CustomEmailObj__c where id =:ID';
           return Database.getQueryLocator(Query);

    }

    global void execute(Database.BatchableContext BC,List<CustomEmailObj__c> CusEmail)
    {

        String url = 'http://google.com/#q=';

        for(CustomEmailObj__c C : CusEmail){
        Body=C.BodyTxt__c;   
        System.debug('333'+Body);
        }
        Body= EncodingUtil.urlEncode(Body, 'UTF-8');
        // build callout
        url += Body; 
        Http h = new Http();
        HttpRequest req = new HttpRequest();
        req.setEndpoint(url);
        req.setMethod('GET');
        req.setTimeout(60000);
       // system.debug('!2222'+req);

        HttpResponse res = h.send(req);

       Integer statusCode = res.getStatusCode();
      // system.debug('!1111'+statusCode);
       String statusName = res.getStatus();
       //system.debug('!33333'+statusName);

    }
    global void finish(Database.BatchableContext BC)
    {

    }

}

我应该使用什么端点url？因为现在我得到 status 301. 我想解析存储在 body 变量中的字符串到 google 搜索引擎

Answer 1

对我来说，它适用于：

https://www.google.com

当然你也必须在远程站点设置中设置这个端点如果我在开发者控制台中执行以下代码：

String url = 'https://www.google.com/#q=';
String body = 'hallo';
url += Body; 
Http h = new Http();
HttpRequest req = new HttpRequest();
req.setEndpoint(url);
req.setMethod('GET');
req.setTimeout(60000);
HttpResponse res = h.send(req);
Integer statusCode = res.getStatusCode();
system.debug(statusCode);
String statusName = res.getStatus();
system.debug(statusName);

结果是：

Debug | 200
Debug | OK
