在后台调用getuserphonenumber接口一直报错,是不能在后台用吗？Calling the getuserphonenumber interface in the background keeps reporting an error. Can it be used in the background?
在后台调用getuserphonenumber接口一直报错,是不能在后台用吗？小程序需要获取手机号，通过界面按钮获取code值后，提交给后台获取手机号：
1、通过接口：https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=""&secret=""获取到access_token值后调用接口：
2、https://api.weixin.qq.com/wxa/business/getuserphonenumber?access_token='+access_token+"&code="+phoneCode，调用后提示：
data format error hint: [Wgdbr7Ore-oEm.7] rid: 62259c4a-7c28684e-6eb764dc
The applet needs to obtain the mobile phone number. After obtaining the code value through the interface button, submit it to the background to obtain the mobile phone number: 1. Through the interface: https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid= "" & Secret = "" get access "_ Token value after calling interface: 2, https://api.weixin.qq.com/wxa/business/getuserphonenumber?access_token= '+access_ Token + "& code =" + phonecode, prompt after calling: data format error hint: [wgdbr7ore OEM. 7] rid: 62259c4a-7c28684e-6eb764dc
回答：
微信的请求都是POST的而且数据是json格式，文档稍微有点误导：
curl -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"code": "e31968a7f94cc5ee25fafc2aef2773f0bb8c3937b22520eb8ee345274d00c144"}' https://api.weixin.qq.com/wxa/business/getuserphonenumber?access_token=ACCESS_TOKENcode不要写在url里面 
群主管理都是支付大佬

需要通过用户触发button按钮返回的code才可以。
