附加信息

The problem is that setPreRequestCallback does not just intercept the query request, it intercepts other requests and not all of those requests have a where property on the content. Some checks need to be added to the setPreRequestCallback function to ensure a query task request. To test this in the sample app (http://jsbin.com/zisoqib/3/edit?js,output) just surround the var y with an if statement as follows. esriRequest.setRequestPreCallback(function (ioArgs) { var x = ioArgs.url.endsWith("query"); if(ioArgs.content && ioArgs.content.where){ var y = ioArgs.content.where.startsWith("xxx"); } return ioArgs; });

解决办法

Setting a definitionExpression on the layer causes the layer to render in the map. See this in the sample provided at http://jsbin.com/zisoqib/3/edit?js,output. Uncommenting both the definitionExpression within the properties of the layer and the line with the ioArgs.content.where, the layer renders in the map without issues.
