Question

在获取Watson Assistant日志时，我需要您的帮助。我收到一个错误“超出速率限制”。根据API文档，我们可以在param中指定游标。当指定了游标时，我们可以每分钟120个请求。如果未指定游标，那么我们只能发出40个请求/ 30分钟。首次启动时，我已将游标属性以空字符串形式传递给“参数”对象，然后将游标值更新为Watson返回的next_cursor值（作为标记的分页属性）。但是，它仍然发出40个请求，并且连接关闭了30分钟。你能告诉我我在做什么错吗？我能够在文本文件中检索40条日志。我正在使用Node JS。我期待着您的回音。

下面是我创建的小样本函数：

const getLogs = () => {
           const params = {
             workspace_id: '50f6598a-a369-45df-9cfb-20bdfe617066',
             cursor: ""
           }
           service.listLogs(params)
           .then(res => {
             if(res.pagination.next_cursor) {
               fs.writeFile("temp.txt", JSON.stringify(res, null, 2), err => {
                 if (err) console.log(err);
                 console.log("Successfully Written to File.");
               });
               params.cursor = res.pagination.next_cursor;
               getLogs()
             } else {
               console.log('no more logs')
             }
           })
           .catch(err => console.log(JSON.stringify(err, null, 2)));
         }
         getLogs();

我认为这可能与递归相关，并且在每次递归开始时将params.cursor设置为“”。您需要做的是将递归与闭包结合起来。因此您的代码将类似于：

 const getLogs = () => {
   const params = {
        workspace_id: '50f6598a-a369-45df-9cfb-20bdfe617066',
        cursor: ""
    }
   function doGetLogs() {
     service.listLogs(params)
     .then(res => {
        if(res.pagination.next_cursor) {
                ...
                params.cursor = res.pagination.next_cursor;
                doGetLogs()
              } 
              ...
            })
           ...
   }
   return doGetLogs();
 }

 getLogs();
