幾年前，我爲一個Parse.com移動應用程序編寫了一些後端代碼，並且剛剛被要求添加一個功能。但是，我發現經過小小的調整後，代碼就不會成功。所以，我回到工作副本，下載，然後部署回來，它也不會工作！我想知道這是否是Parse軟件的變化？解析雲代碼保存問題
代碼在保存方法失敗，因爲所有的日誌都很好。錯誤情況的日誌顯示'沒有提供信息'。如果我不使用消息屬性，它只會顯示「{}」，所以我認爲它是空的。在錯誤情況下，我已將承諾解決方案放在調試時停止作業超時。我從來沒有理解的一件事是爲什麼我必須製作兩個Seed對象，然後從一個對象上正確保存。如果我做了一個.save（null，...）它將無法工作。
任何幫助將是太棒了。謝謝！
PS：對於下面的縮進道歉 - 在我的文件中是正確的。
function flush() {
//Clear the previous records from the class.
var Seed = Parse.Object.extend("Seeds");
var _ = require("underscore");
var arr = [];
var query = new Parse.Query(Seed);
return query.find().then(function(oldSeeds) {
_.each(oldSeeds, function(oldSeed) {
arr.push(oldSeed.destroy());
});
return Parse.Promise.when(arr);
});
}
Parse.Cloud.job("fetchjson", function(request, status) {
var url = 'someurl';
flush().then(function() { Parse.Cloud.httpRequest({url: url}).then(function(httpResponse){
var Seed = Parse.Object.extend("Seeds");
var jsonobj = JSON.parse(httpResponse.text);
var _ = require("underscore");
var results = [];
// do NOT iterate arrays with `for... in loops`
_.each(jsonobj.seeds, function(s) {
var p = new Parse.Promise();
results.push(p); // Needs to be done here or when() will execute immediately with no promises.
var seed = new Seed();
var a = new Seed(s);
var image_url = a.get("image")
//Get the JSON.
Parse.Cloud.httpRequest({url: image_url}).then(function(response) {
console.log("Fetching image at URL: " + image_url);
//Create a new image object and save, passing ref through promise.
var file = new Parse.File('thumb.jpg', { base64: response.buffer.toString('base64', 0, response.buffer.length) });
return file.save();
}).then(function(thumb) {
console.log("Attaching thumb to object");
//Set image ref as object attribute.
a.set("imageFile", thumb);
console.log("Parsing views into viewsint");
//Save decimal string as int into another attribute.
a.set("viewsInt", parseInt(a.get("views")));
console.log("Parsing description into descriptionarray");
//Save string as array into another attribute.
var dar = new Array(1);
//dar[0] = a.get("description")
a.set("descriptionarray", [a.get("description")]);
}, function(error) {
console.log("Error occurred :(");
}).then(function(){
console.log("Saving object");
//Save the object and resolve the promise so we can stop.
seed.save(a,{
success: function(successData){
console.log(successData);
p.resolve(successData);
},
error: function(error){
console.log(error.message);
p.resolve(error);
}
});
});
});
// .when waits for all promises to be resolved. This is async baby!
Parse.Promise.when(results).then(function(data){
console.log("All objects saved");
status.success("Updated Succesfully");
});
}, function(error) {
//Oh noes :'(
console.error('Request failed with response code ' + httpResponse.status);
status.error("Update Failed");
});
});
});
