我有一个云代码脚本,可以从服务中提取一些JSON。该 JSON 包括一个对象数组。我想将这些对象保存到 Parse,但要使用特定的 Parse 类。我如何才能做到这一点?
这是我的代码。
Parse.Cloud.httpRequest({
url: 'http://myservicehost.com',
headers: {
'Authorization': 'XXX'
},
success: function(httpResponse) {
console.log("Success!");
var json = JSON.parse(httpResponse.text);
var recipes = json.results;
for(int i=0; i<recipes.length; i++) {
var Recipe = Parse.Object.extend("Recipe");
var recipeFromJSON = recipes[i];
// how do i save recipeFromJSON into Recipe without setting all the fields one by one?
}
}
});
我想我知道该怎么做了。你需要将JSON数据对象中的className属性设置为你的类名。(在 源码)但我只在客户端尝试了一下。
for(int i=0; i<recipes.length; i++) {
var recipeFromJSON = recipes[i];
recipeFromJSON.className = "Recipe";
var recipeParseObject = Parse.Object.fromJSON(recipeFromJSON);
// do stuff with recipeParseObject
}
这个页面的例子 https:/parse.comdocsjsguide
var GameScore = Parse.Object.extend("GameScore");
var gameScore = new GameScore();
gameScore.save({
score: 1337,
playerName: "Sean Plott",
cheatMode: false
}, {
success: function(gameScore) {
// The object was saved successfully.
},
error: function(gameScore, error) {
// The save failed.
// error is a Parse.Error with an error code and message.
}
});
IHMO这个问题并不是重复的。如何使用Parse.Object fromJSON?[重复]
在这个问题中,JSON并不是由Parse.Object.toJSON函数本身生成的,而是来自另一个服务。
const object = new Parse.Object('MyClass')
const asJson = object.toJSON();
// asJson.className = 'MyClass';
Parse.Object.fromJSON(asJson);
// Without L3 this results into:
// Error: Cannot create an object without a className
// It makes no sense (to me) why the Parse.Object.toJSON is not reversible
