最后有完整代碼
1、獲取code
onShow: function() {
var that = this;
//獲取用戶的本地緩存數(shù)據(jù)，userinfo信息是在用戶授權(quán)登錄時(shí)保存的
var n = wx.getStorageSync("userinfo");
//當(dāng)本地緩存的用戶名稱不為""或者null時(shí)，設(shè)置userinfo信息
if(n.nickName != '' && n.nickName != null){
this.setData({
userinfo: n,
hasUserInfo:true,
canIUseGetUserProfile:true
})
// 通過wx.login獲取登錄憑證（code），然后通過code去獲取我們用戶的openid
wx.login({
success:(res)=>{
console.log(res);
that.getOpenId();
},
})
}
},
2、利用code獲取sessionkey
小程序端：
getOpenId(){
var that=this
wx.login({
success (res) {
if (res.code) {
//發(fā)起網(wǎng)絡(luò)請(qǐng)求
wx.request({
url: '自己的Control路徑',
data: {
code: res.code
},
method: 'get',
header: {
'content-type': 'application/json' //默認(rèn)值
},
success: function(res) { //res就是接收后臺(tái)返回的數(shù)據(jù)
console.log(res.data);
that.setData({
sessionkey:res.data
})
},
})
} else {
console.log('登錄失敗！' + res.errMsg)
}
}
})
},
Java后臺(tái)：
@RequestMapping("名稱") //獲取sessionid
@ResponseBody
public static void getOpenId(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String appId="自己的appid";
String secret="小程序密鑰";
String code=request.getParameter("code");
System.out.println(code);
String url = "https://api.weixin.qq.com/sns/jscode2session?appid=" + appId
+ "&secret=" + secret + "&js_code=" + code + "&grant_type=authorization_code";
//這三個(gè)參數(shù)就是之后要填上自己的值。
//替換appid，appsecret，和code
String requestUrl = url;
//調(diào)用get方法發(fā)起get請(qǐng)求，并把返回值賦值給returnvalue
String returnvalue=GET(requestUrl);
System.out.println(requestUrl);//打印發(fā)起請(qǐng)求的url
System.out.println(returnvalue);//打印調(diào)用GET方法返回值
//定義一個(gè)json對(duì)象。
JSONObject convertvalue=new JSONObject();
//將得到的字符串轉(zhuǎn)換為json
convertvalue=(JSONObject) JSON.parse(returnvalue);
System.out.println("return openid is ："+(String)convertvalue.get("openid")); //打印得到的openid
System.out.println("return sessionkey is ："+(String)convertvalue.get("session_key"));//打印得到的sessionkey，
//把openid和sessionkey分別賦值給openid和sessionkey
String openid=(String) convertvalue.get("openid");
String sessionkey=(String) convertvalue.get("session_key");//定義兩個(gè)變量存儲(chǔ)得到的openid和session_key.
Gson gson=new Gson();
String json = gson.toJson(sessionkey);
Writer out = response.getWriter();
out.write(String.valueOf(json));
out.flush();
}
//發(fā)起get請(qǐng)求的方法。
public static String GET(String url) {
System.out.println("start");//打印發(fā)起請(qǐng)求的url
String result = "";
BufferedReader in = null;
InputStream is = null;
InputStreamReader isr = null;
try {
URL realUrl = new URL(url);
URLConnection conn = realUrl.openConnection();
conn.connect();
Map<String, List<String>> map = conn.getHeaderFields();
is = conn.getInputStream();
isr = new InputStreamReader(is);
in = new BufferedReader(isr);
String line;
while ((line = in.readLine()) != null) {
result += line;
}
} catch (Exception e) {
// 異常記錄
} finally {
try {
if (in != null) {
in.close();
}
if (is != null) {
is.close();
}
if (isr != null) {
isr.close();
}
} catch (Exception e2) {
// 異常記錄
}
}
return result;
}
獲取小程序密鑰：微信公眾平臺(tái)->開發(fā)管理->開發(fā)設(shè)置
3、獲取iv和encryptedData并解密獲取手機(jī)號(hào)
getPhoneNumber(e) {
var that=this;
console.log("手機(jī)號(hào)：")
wx.request({
url: '自己的Control路徑',
data: {
sessionkey: that.data.sessionkey,
iv:e.detail.iv,
encryptedData:e.detail.encryptedData
},
method: 'get',
header: {
'content-type': 'application/json' //默認(rèn)值
},
success: function(res) { //res就是接收后臺(tái)返回的數(shù)據(jù)
console.log(res.data);
},
})
}
java后臺(tái)：
@RequestMapping("decryptS5") //解密獲取手機(jī)號(hào)
@ResponseBody
public static String decryptS5(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String sSrc=request.getParameter("encryptedData");
String encodingFormat="utf-8";
String sKey=request.getParameter("sessionkey");
String ivParameter=request.getParameter("iv");
try {
BASE64Decoder decoder = new BASE64Decoder();
byte[] raw = decoder.decodeBuffer(sKey);
SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES");
IvParameterSpec iv = new IvParameterSpec(decoder.decodeBuffer(ivParameter));
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.DECRYPT_MODE, skeySpec, iv);
byte[] myendicod = decoder.decodeBuffer(sSrc);
byte[] original = cipher.doFinal(myendicod);
System.out.println(new String(original, encodingFormat));
return new String(original, encodingFormat);
} catch (Exception ex) {
return null;
}
}
