Question

我正在尝试使用REST接口将以下内容发送到Neo4j，特别是2.2.9手动教程中给出的关于使用Java的REST，sendTransactional Cypher查询的方法。但是，正如您在下面看到的，我继续收到一个似乎与查询本身无关的错误。

有关如何调试此内容的任何提示？

CREATE (p:player { props }), "parameters" { 
     "props" : { 
          "screen_name" : "testone", 
          "email" : "test.one@gmail.com", 
          "rank" : "-12", 
          "password" : "testonepass", 
          "details" : "test one details", 
          "latitude" : "0.0", 
          "longitude" : "0.0", 
          "available" : "true", 
          "publish" : "true" }}

{"results":[],"errors":[{"code":"Neo.ClientError.Request.InvalidFormat","message":"Unable to deserialize request: Unexpected character ('p' (code 112)): was expecting comma to separate OBJECT entries\n at [Source: HttpInputOverHTTP@10401de; line: 1, column: 66]"}]}

从您发布的代码段中，看起来事务端点的有效内容不完整。您可以在浏览器中尝试此语句。我刚刚复制了你的声明并对其进行了格式化，以便将其发布到浏览器中。然后你至少可以看到它的工作。很明显，数据正在发布，似乎只是归结为格式化。

:POST /db/data/transaction/commit {
"statements": [
    {
        "statement": "CREATE (p:player { props })",
        "parameters": 
            {
                "props" : { 
                    "screen_name" : "testone", 
                    "email" : "test.one@gmail.com", 
                    "rank" : "-12", 
                    "password" : "testonepass", 
                    "details" : "test one details", 
                    "latitude" : "0.0", 
                    "longitude" : "0.0", 
                    "available" : "true", 
                    "publish" : "true" }  
             }
        }
    ]
}

这个Cypher查询有什么问题？
