Sql server 在节点/角度应用程序中创建新MSSQL记录的问题

我正试图通过我的节点/角度应用程序在现有Azure MSSQL数据库中创建新行。GET请求正确触发，我用来生成数据的表单根据我所知道的正确生成JSON，但是当POST函数触发时，我得到以下错误：

Trace: { RequestError: JSON text is not properly formatted. Unexpected character 'o' is found at position 1.
    at RequestError (C:\Users\jlea\Desktop\Code\tnplan-boot\node_modules\tedious\lib\errors.js:34:12)

events.js:167
      throw er; // Unhandled 'error' event
      ^

和我的sql路由代码：

const router = require('express').Router();
const TYPES = require('tedious').TYPES;

/* GET reports. */
router.get('/', function (req, res) {

  req.sql("select * from jacksonwaste for json path")
    .into(res, '[]');

});

/* GET single report. */
router.get('/:id', function (req, res) {

  req.sql("select * from jacksonwaste where id = @id for json path, without_array_wrapper")
    .param('id', req.params.id, TYPES.Int)
    .into(res, '{}');

});

/* POST create report. */
router.post('/', function (req, res) {

  req.sql("exec createReport @report")
    .param('report', req.body, TYPES.NvarChar)
    .exec(res)
    console.log(req.body);
});

/* PUT update report. */
router.put('/:id', function (req, res) {

  req.sql("exec updateReport @id, @report")
    .param('id', req.params.id, TYPES.Int)
    .param('report', req.body, TYPES.NvarChar)
    .exec(res);

});

/* DELETE single report. */
router.delete('/:id', function (req, res) {

  req.sql("delete from jacksonwaste where id = @id")
    .param('id', req.params.id, TYPES.Int)
    .exec(res);

});

module.exports = router;

最后，我的mssql存储过程代码：

/****** Object:  StoredProcedure [dbo].[createReport]    Script Date: 8/15/2018 9:13:31 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER procedure [dbo].[createReport](@report nvarchar(max))
as begin
SET NOCOUNT ON
    insert into jacksonwaste (reportuser, reportdate, percentcomp, err, errdate, acquisition, acqdate, pns, pnsdate, bidtabs, bidtabsdate, constructionstart, constartdate, constructionend, conenddate, monitored, monitorready,
    contractoractivity, lastcafsubmission, mostrecentinvoice, phases, phaseupdate, hasoccured, willoccur, issues, tnecdhelp)
    select *
    from OPENJSON(@report) 
            WITH (  
            reportuser nvarchar(128), 
            reportdate date,
            percentcomp int,
            err bit,
            errdate date,
            acquisition bit,
            acqdate date,
            pns bit,
            pnsdate date,
            bidtabs bit,
            bidtabsdate date,
            constructionstart bit,
            constartdate date,
            constructionend bit,
            conenddate date,
            monitored bit,
            monitorready bit,
            contractoractivity bit,
            lastcafsubmission date,
            mostrecentinvoice date,
            phases bit,
            phaseupdate nvarchar(1000),
            hasoccured nvarchar(1000),
            willoccur nvarchar(1000),
            issues nvarchar(1000),
            tnecdhelp nvarchar(1000)
            )
end

编辑：添加了正在传递到sql请求的JSON对象，以显示我看不到任何意外字符：

{ reportuser: 'john',
  reportdate: '2018-08-11',
  percentcomp: '4',
  err: true,
  pns: true,
  pnsdate: '2018-08-04',
  errdate: '2018-08-16',
  constructionstart: true,
  constartdate: '2018-08-29',
  lastcafsubmission: '2018-08-23',
  mostrecentinvoice: '2018-08-24',
  phaseupdate: 'test',
  hasoccured: 'test',
  willoccur: 'test',
  issues: 'test',
  tnecdhelp: 'test' }

我错在哪里了？

记录在案，希望这对将来的人有所帮助：

我最近遇到了一个非常类似的问题（完全相同的

RequestError

），并发现我将JSON作为一个对象传递，而Express4Teduous需要一个字符串

JSON.stringify（req.body）

成功了

换言之，改变你的

req.sql("exec updateReport @id, @report") .param('id', req.params.id, TYPES.Int) .param('report', req.body, TYPES.NvarChar) .exec(res); sql（“exec updateReport@id，@report”） .param（'id'，req.params.id，TYPES.Int） .param（'report'，req.body，TYPES.NvarChar） .exec（res）； 到

sql（“exec updateReport@id，@report”） .param（'id'，req.params.id，TYPES.Int） .param（'report'，JSON.stringify（req.body），TYPES.NvarChar） .exec（res）；

解决了我的问题。

您可能希望在错误中看到这一点：“JSON文本格式不正确。在位置1处发现意外字符“o”，我已尝试过，但当我记录正在发送的req.body时，没有类似的字符。编辑了我的帖子，以包含我启动提交时记录到终端的内容。您可能希望尝试在调试器中查看JSON，而不是将其注销。对。很明显，正在传递的JSON对象的格式不正确，我很难理解它发生的原因/地点。你是如何解决这个问题的？我得到了相同的第一个错误（字符“o”位于位置1）…这也是我的mmsql问题。谢谢 req.sql("exec updateReport @id, @report") .param('id', req.params.id, TYPES.Int) .param('report', req.body, TYPES.NvarChar) .exec(res); req.sql("exec updateReport @id, @report") .param('id', req.params.id, TYPES.Int) .param('report', JSON.stringify(req.body), TYPES.NvarChar) .exec(res);
