按照关于如何"Write an API“的教程,我似乎被卡住了,除了如何让生成的API键显示在模板中之外,我不能再继续前进了。
我在助手中有一个查询APIKeys.find().fetch()
,它应该正确地反映在html模板中,但它没有。我花了几个小时检查我的代码,没有注意到代码中的任何错误。
我对Meteor并不陌生,这使得它更加令人讨厌!
请帮帮忙!
在模板代码下面找到:/client/main.html
<template name="apiKey">
<div class="row">
<div class="col-xs-12 col-sm-6">
<h4 class="page-header">Your API Key</h4>
<p>To gain access to the Pizza API, use the following API Key.
Make sure to keep it super safe! <strong>If you'd like to
generate a new key, click the "refresh" icon on the field
below</strong>.</p>
<label class="sr-only" for="apiKey">Your API Key</label>
<div class="input-group">
<input type="text" readonly class="form-control" id="apiKey" placeholder="API Key" value="{{apiKey}}">
<div class="input-group-addon regenerate-api-key"><span class="glyphicon glyphicon-refresh"></span></div>
</div>
</div>
在上面的模板中,value="{{apiKey}}"
下的模板中没有呈现任何内容。我不明白为什么会这样。
在我的助手代码下面找到:/client/main.js
import '../imports/api/tasks.js';
Template.apiKey.helpers({
apiKey: function() {
var apiKey = APIKeys.findOne();
if ( apiKey ) {
return apiKey.key;
console.log("Sucessful");
}
else {
console.log("Failed! Can't find: APIKeys.findOne()");
}
}
});
上面的帮助器代码在控制台中呈现这段代码:Failed! Can't find: APIKeys.findOne()
。此外,当我在控制台中查询APIKeys.find().fetch()
时,我得到的结果是:
[]
在我的onCreated代码下面找到:/client/main.js
Template.apiKey.onCreated(function(){
console.log("Your in onCreated!");
this.subscribe( "APIKey" );
});
上面的onCreated代码在控制台Your in onCreated!
中呈现这段代码。
在我的事件代码下面可以找到触发生成新的API键的代码:/client/main.js
import '../imports/api/tasks.js';
Template.apiKey.events({
'click .regenerate-api-key': function( ){
var userId = Meteor.userId();
confirmRegeneration = confirm( "Are you sure? This will
invalidate your current key!" );
if ( confirmRegeneration ) {
Meteor.call( "regenerateApiKey", userId, function( error, response ) {
if ( error ) {
alert( error.reason, "danger" );
}
else {
alert( "All done! You have a new API key: " +response );
console.log("Response is: " +response);
}
});
}
}
});
上面的事件代码使用:All done! You have a new API key: 0
呈现一个弹出框。控制台还会呈现:Response is: 0
。
在下面的regenerateApiKey
方法代码/server/main.js中可以找到
Meteor.methods({
regenerateApiKey: function( userId ){
check( userId, Meteor.userId() );
var newKey = Random.hexString( 32 );
console.log(">>>: " +newKey);
try {
var keyId = APIKeys.update( { "owner": userId }, {
$set: {
"key": newKey
}
});
console.log(">>> newKey : " +keyId);
return keyId;
} catch(exception) {
console.log("FAILED UPDATE")
return exception;
}
}
});
上面的方法代码在终端中呈现以下内容:
>>>: af3233a999308e39f9471b790e121cf5
>>> newKey : 0
我已经将代码中的问题缩小到了以下范围。keyId
变量等于"0“表示APIKeys集合没有更新。有人能解释为什么会发生这种情况吗?
我已经包含了更多的信息,希望它能有所帮助。
在下面的代码中,我订阅了/client/main.js
Router.route('/apiKey', {
template: 'apiKey',
waitOn: function(){
return Meteor.subscribe('APIKey');
}
});
在我发布/server/main.js的代码下面找到
Meteor.publish( 'APIKey', function(){
var user = this.userId;
var data = APIKeys.find( { "owner": user }, {fields: { "key": 1 } } );
if ( data ) {
console.log("User: " +user+ " data is: " +data);
console.log("Was able to find data in Publish APIKey!");
console.log(APIKeys.find().fetch());
return data;
}
return this.ready();
});
上面的发布代码在终端中呈现以下内容:
User: xELzNtMQp7u9FpZib data is: [object Object]
Was able to find data in Publish APIKey!

可以在下面的代码中找到我声明集合imports/api/tasks.js的位置
import { Mongo } from "meteor/mongo";
import { Template } from 'meteor/templating';
import { ReactiveVar } from 'meteor/reactive-var';
global.APIKeys = new Meteor.Collection("apiKeys");
/*
* Allow
*/
APIKeys.allow({
insert: function(){
// Disallow inserts on the client by default.
return false;
},
update: function(){
// Disallow updates on the client by default.
return false;
},
remove: function(){
// Disallow removes on the client by default.
return false;
}
});
/*
* Deny
*/
APIKeys.deny({
insert: function(){
// Deny inserts on the client by default.
return true;
},
update: function(){
// Deny updates on the client by default.
return true;
},
remove: function(){
// Deny removes on the client by default.
return true;
}
});

当您尝试更新数据库时,问题看起来像是数据库中没有任何密钥
尝试用APIKeys.upsert
替换APIKeys.update
,如果不存在键,这将创建一个键。
try {
var keyId = APIKeys.upsert( { "owner": userId }, {
$set: {
"key": newKey
}
});
