我需要以编程方式为模型运行远程挂钩。我怎样才能做到这一点?
最佳答案
我没有找到任何解决方案并实施了我的解决方案
/**
* Trigger execution of remote hooks of a model
*
* @param app The loopback application
* @param modelName The model name
* @param data The model data
* @param when The possible values are 'before' or 'after'
* @param method The remote method name
* @param ctx The hooks context
* @param next
*/
exports.execHooks = function(app, modelName, data, when, method, ctx, next) {
// Save original context values
var originalData = ctx.args.data || {};
var originalMethod = ctx.method;
// Get shared method
var modelSharedClass = app.remotes().classes().filter(function(item) {
return item.name === modelName;
})[0];
var modelSharedMethod = modelSharedClass.methods().filter(function(item) {
return item.name === method;
})[0];
// Change context data
ctx.args.data = data;
ctx.method = modelSharedMethod;
ctx.methodString = modelSharedMethod.stringName;
// Execute hooks
var remoteObject = app.remoteObjects()[modelName];
app.remotes().execHooks(when, modelSharedMethod, remoteObject, ctx, function(err) {
// Restore context data
var changedData = ctx.args.data;
ctx.args.data = originalData;
ctx.method = originalMethod;
ctx.methodString = originalMethod.stringName;
next(err);
});
};
使用示例:
utils.execHooks(app, app.models.MyModel, model, 'before', 'create', ctx);
