Firebase Realtime equalTo不能与"+123"之类的String一起使用. [英] Firebase Realtime equalTo not working with String like "+123"

问题描述

我遇到问题，找不到答案.这是我的示例Firebase数据库，在移动"数据库上有一个索引.:

I have an issue and can't find the answer. Here is my sample firebase database, with an index on "mobile" :

test
 A
  mobile : "+1234567"
 B
  mobile : "+2345678"

现在我要查询所有具有mobile ="+1234567"的节点

Now I want to query all node with mobile = "+1234567"

test.json?orderBy="mobile"&equalTo="+1234567"
returns : { }

但是

test.json?orderBy="mobile"&startAt="+1234567"
returns :
{
  "A" : {
    "mobile" : "+1234567"
  },
  "B" : {
    "mobile" : "+2345678"
  }
}

和

test.json?orderBy="mobile"&startAt="+1234567"&endAt="+1234567"
returns : { }

怎么了?如果我删除所有"+"号，效果很好迹象(数据库+请求中)?！

What's wrong ? It works fine if I remove all "+" signs (in database + requests) ?!

推荐答案

您需要URL编码 + 字符，表示将其显示为％2B .

You'll need to URL encode the + character, meaning show it as %2B.

所以:

test.json?orderBy="mobile"&startAt="+1234567"&endAt="%2B1234567"

在这里查看我的工作示例: https://stackoverflow.firebaseio.com/65924783.json?orderBy=%22mobile%22&Toal==%22%2B1234567%22

See my working example here: https://stackoverflow.firebaseio.com/65924783.json?orderBy=%22mobile%22&equalTo=%22%2B1234567%22
