Question

我从parse.com迁移到托管的ParseSever。大多数事情都有效，但我发现对于一个类，字段不会更新。 HTTP请求在日志中返回200，在Python中，updatedAt字段显示最近的时间戳，但字段不会更改。在下面的python代码及其打印输出中，字段field1和field2继续显示旧值，即使在updatedAt和HTTP响应检出时也是如此。从REST API更新到其他类通常是有效的（没有详尽检查）。 SDK的更新正在运行。在parse.com上完美运行。类和条目的ACL是公共的。

def updateObjectWithId(self,objectId, objectJson):
        self.connection.connect()
        if(objectId == ""):
            self.connection.request('POST','/parse/classes/'+self._className,objectJson,
                    {
                    "X-Parse-Application-Id": self.appId,
                   "X-Parse-Master-Key": self.masterApiKey
                                })
        else:
            print "ParseArchiver.updateObjectWithId: id: ", objectId, " of Class: ", self._className, " with json: ", objectJson
            self.connection.request('PUT','/parse/classes/'+self._className+'/'+objectId,objectJson,
                    {
                    "X-Parse-Application-Id": self.appId,
                   "X-Parse-Master-Key": self.masterApiKey
                                })
        result = json.loads(self.connection.getresponse().read())
        time.sleep(ParseArchiver.ParseSleepTime)
        print "*** ParseArchiver.updateObjectWithId: Result object is:",result

        return

输出：

*** ParseArchiver.updateObjectWithId: Result object is: {u'updatedAt': u'2016-06-22T16:38:55.690Z'}

Answer 1

我发现每个非GET请求现在必须有一个“Content-Type”字段。这在parse.com上不是必需的。我想可能是ParseServer可以设置一个默认的内容类型，允许一个省略这个参数，然后旧的代码将无需修改。修改后的工作代码段如下：

abc

从parse.com迁移到ParseServer后，数据库字段不通过REST API更新
