OrientDb：创建边缘时解组JSON内容时出错

Question

I set up this piece of JSON to use with the OrientDb http API at url /batch/db. I am trying to create an edge of class "cef_CONSISTSOF_cef" which is subclassed from "E".

{"transaction":true, 
 "operations":[ 
    {"type":"c", 
     "record":{ 
        "@class":"cef_CONSISTSOF_cef", 
        "out":"#12:37847", 
        "in":"#12:37641"}
       } 
  ]}

In response I get the following:

{ "errors": [ 
   { "code": 500, "reason": 500, 
  "content": 
    "com.orientechnologies.orient.core.exception.OSerializationException: Error on unmarshalling JSON content 
  '{\"transaction\":true,\"operations\":[{\"type\":\"c\",\"record\":
    {\"@class': content must be between { }" } ] }

Any ideas on what I have done wrong?

I tried your case with this following simple dataset and by using Postman and OrientDB 2.1.15

I can give you two options to create the edge througt HTTP request:

1. USING "type" : "cmd" :

2. USING "type" : "script" :

1. USING "type" : "c" :
