Cosmos db readDocument API在存储过程中不起作用 [英] Cosmos db readDocument api not work in stored procedure

问题描述

使用CosmosDB/DocumentDB中的 readDocument 函数的简单存储过程，但是不起作用.

A simple stored procedure using readDocument function in CosmosDB/DocumentDB, but it does not work.

function testRead() {
    var collection = getContext().getCollection();

    var docId =  collection.getSelfLink() + 'docs/myDocId';

    // Query documents and take 1st item.
    var isAccepted = collection.readDocument(docId, {}, function (err, doc, options) {
        if (err) throw err;

        response.setBody(JSON.stringify(doc));
    });

    if (!isAccepted) throw new Error('The query was not accepted by the server.');
}

它总是显示错误代码400.

it always get error code 400.

{"code":400，"body":"{\" code \:\" BadRequest \，\" message \:\"消息:{\\错误\\":[\\执行Java脚本时遇到异常.异常=错误:创建请求消息时出错\\ r \\ nStack跟踪:错误:在readDocument上创建请求消息时出错\\ n(testRead.js:512:17)\\ n在testRead(testRead.js:8:5)\\ n在__docDbMain(testRead.js:18:5)\\ n位于全局代码(testRead.js:1:2)\\]} \ r \ nActivityId:2fb0f7ef-c192-4b56-b8bb-9681c9f8fa6e，请求URI:/apps/DocDbApp/services/DocDbServer22/partitions/a4cb4962-38c8-11e6-8106-8cdcd42c33be/replicas/1p/，RequestStats:，SDK:Microsoft.Azure.Documents.Common/1.22.0.0 \}"，"activityId":"2fb0f7ef-c192-4b56-b8bb-9681c9f8fa6e"，"substatus":400}

推荐答案

根据迈克尔的建议，我的示例现在可以工作了，下面是代码

According to Michael's suggestion, my sample works now, here is the code

function testRead() {
    var collection = getContext().getCollection();
    var response = getContext().getResponse();

    var docId =  collection.getAltLink() + '/docs/myDocId';

    // Query documents and take 1st item.
    var isAccepted = collection.readDocument(docId, {}, function (err, doc, options) {
        if (err) throw err;

        response.setBody(JSON.stringify(doc));
    });

    if (!isAccepted) throw new Error('The query was not accepted by the server.');
}
