目录获取手机号注意:使用方法前端templatejs后端appsetting配置Startup.csGlobalContext.cs调用获取截图获取手机号 从基础库 2.21.2 开
从基础库 2.21.2 开始,对获取手机号的接口进行了安全升级,以下是新版本接口使用指南。( 旧版本接口 目前可以继续使用,但建议开发者使用新版本接口,以增强小程序安全性)
因为需要用户主动触发才能发起获取手机号接口,所以该功能不由 api 来调用,需用 button 组件的点击来触发。另外,新版本接口 不再 需要提前调用 wx.login
进行登录。
需要将 button 组件 open-type
的值设置为 getPhoneNumber
,当用户点击并同意之后,可以通过 bindgetphonenumber
事件回调获取到动态令牌 code
,然后把 code
传到开发者后台,并在开发者后台调用微信后台提供的 phonenumber.getPhoneNumber 接口,消费 code
来换取用户手机号。每个 code
有效期为5分钟,且只能消费一次。
注: getPhoneNumber
返回的 code
与 wx.login
返回的 code
作用是不一样的,不能混用。
使用getphonenumber获取回调code
//小程序写法
<button open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber"></button>
//uni-app写法
<button class="wx-login" open-type="getPhoneNumber" @getphonenumber="getPhoneNumber">微信用户一键登录</button>
调用服务器的url,消费 code
来换取用户手机号
methods: {
getPhoneNumber: function(e) {
var that = this;
var userPhone = uni.getStorageSync('userPhone');
if(userPhone != '')
{
getApp().globalData.userPhone = userPhone;
uni.navigateTo({
url: 'personal'
});
return;
}
if (e.detail.errMsg == "getPhoneNumber:ok") {
//端口号是由后端服务器生成
wx.request({
url: '后端服务URL',
data: {
code: e.detail.code
},
method: "get",
success: function(res) {
uni.setStorageSync('userPhone', res.data);
getApp().globalData.userPhone = res.data;
uni.navigateTo({
url: 'personal'
});
},
fail: function(res) {
console.log(res.errMsg)
}
})
}
}
}
后端使用.net core配置api
"Wx": {
"appid": "",
"secret": "",
"baseurl": "https://api.weixin.qq.com/",
"getToken": "cgi-bin/token?grant_type=client_credential&appid={0}&secret={1}",
"getuserphonenumber": "wxa/business/getuserphonenumber?access_token={0}"
}
注册HttpClient调用微信API
public void ConfigureServices(IServiceCollection services)
{
services.AddHttpClient("WxClient", config =>
{
config.BaseAddress = new Uri(Configuration["Wx:baseurl"]);
config.DefaultRequestHeaders.Add("Accept", "application/JSON");
});
}
public void Configure(IApplicationBuilder app, IWEBHostEnvironment env)
{
GlobalContext.HttpClientFactory = app.ApplicationServices.GetService<IHttpClientFactory>();
}
获取token方法与获取手机号方法,通过HTTPClient调用获取Token方法,用Token和Code调用 getuserphonenumber获取用户手机号

{

var requestBuild = Configuration["Wx:getToken"];
requestBuild = string.FORMat(requestBuild,

);
using (var wxClient = HttpClientFactory.CreateClient("WxClient"))
{
var httpResponse = wxClient.GetAsync(requestBuild).Result;
var dynamic = JsonConvert.DeserializeObject<dynamic>(
httpResponse.Content.ReadAsStringAsync().Result
);
if (dynamic.errmsg == null)//刷新Token
{
Token = dynamic.access_token;
var expires_in = Convert.ToDouble(dynamic.expires_in);
TimeOutDate = DateTime.Now.AddSeconds(expires_in);
return new Result(Token);
}
else
{
return new Result(errMsg:dynamic.errmsg);
}
}
}
else
{
return new Result(Token);
}
}
public static Result GetUserPhoneNumber(string code)
{
var token = GetToken();
if(!token.isSuccess)
{
return token;
}
//构造请求链接
var requestBuild = Configuration["Wx:getuserphonenumber"];
requestBuild = string.Format(requestBuild, token.data);
//建立HttpClient
using (var wxClient = HttpClientFactory.CreateClient("WxClient"))
{
string content = $"{{\"code\":\"[code]\"}}";
byte[] data = Encoding.UTF8.GetBytes(content);
var bytearray = new ByteArrayContent(data);
var httpResponse = wxClient.PostAsync(requestBuild, bytearray).Result;
var dynamic = JsonConvert.DeserializeObject<dynamic>(
httpResponse.Content.ReadAsStringAsync().Result
);
if (dynamic.errmsg == "ok")
return new Result(dynamic.phone_info.phoneNumber.ToString());
else
return new Result(errMsg: dynamic.errmsg.ToString());
}
}

public Result(string errMsg,bool isSuccess = false)
{
this.errMsg = errMsg;
this.isSuccess = isSuccess;
}
public string data { get; set; }
public string errMsg { get; set; }
public bool isSuccess { get; set; }
}
}
}
[HttpGet]
public string GetPhone(string code)
{
var phone = GlobalContext.GetUserPhoneNumber(code);
if(!phone.isSuccess)
{
//错误处理

return phone.data;
}
