Question

下面的说明在curl命令中发送json请求有效负载

https://docs.wso2.com/display/DSS351/JSON+Mapping+Sample。

以下是curl命令：

D:\testing\curl-7.46.0-win64\bin>curl -X POST -H 'Accept: application/json'  -H 'Content-Type: application/json' --data "@article-payload.json" http://8.39.51.27:9763/services/KMTool/insertarticles

错误：

**Error: Getting below error:**

我将文件保存在以下位置：

C:\Users\testUser\Downloads\wso2dss-3.5.1\repository\deployment\server\dataservices\article-payload.json

不确定是什么原因造成的。只需按照wso2dss文档提供的说明进行操作。

似乎参数未正确传递（例如：articleTitle已变为null，但在数据库表中，您已将其定义为非空列）。 article-payload.json文件应该位于您尝试使用curl调用请求的目录中（即在D：\ testing \ curl-7.46.0-win64 \ bin中）

WSO2DSS - JSON格式的REST POST操作调用：异常
