微信公众号测试账号页面申请测试账号

第一步：填写服务器配置
URL
http://*******************/wechatLogin/checkSignatureToken
hello
配置授权回调页面域名
体验接口权限表 --> 更多操作网页服务 --> 网页帐号 --> 网页授权获取用户基本信息
houhouhou.nat100.top
第二步：验证消息的确来自微信服务器
/**
* 验证服务器地址的有效性
*/
@Value("${wechat.TOKEN}")
private String TOKEN;
//wechat:
// TOKEN: hello #接口配置信息的TOKEN
@GetMapping("/checkSignature")
public String checkSignature(@RequestParam(value = "signature") String signature,
@RequestParam(value = "timestamp") String timestamp,
@RequestParam(value = "nonce") String nonce,
@RequestParam(value = "echostr") String echostr){
String[] params = new String[]{nonce,timestamp,TOKEN};
Arrays.sort(params);
String signatureResult = DigestUtils.sha1Hex(params[0]+params[1] + params[2]);
//校验签名
if(!signatureResult.equals(signature)) {
throw new RuntimeException("signature is not the same wechat signature is " + signature + " signatureResult is " + signatureResult);
}
return echostr;
}
第三步：依据接口文档实现业务逻辑
控制层
@RestController
@RequestMapping("/wechatLogin")
public class WechatLoginController {
@Autowired
WechatLoginService wechatLoginService;
/**
* 生成用户同意授权页面url
*
* @return
*/
@GetMapping("/authorize")
public String getRequestCodeUrl() {
return wechatLoginService.getRequestCodeUrl();
}
/**
* 微信用户登陆
* @param code
* @return
*/
@GetMapping("/login")
public AjaxResult login(@RequestParam("code") String code) {
return AjaxResult.success(wechatLoginService.login(code));
}
//
/**
* 验证服务器地址的有效性
*/
private static final String TOKEN = "wl123";
@GetMapping("/checkSignature")
public String checkSignature(@RequestParam(value = "signature") String signature,
@RequestParam(value = "timestamp") String timestamp,
@RequestParam(value = "nonce") String nonce,
@RequestParam(value = "echostr") String echostr){
String[] params = new String[]{nonce,timestamp,TOKEN};
Arrays.sort(params);
String signatureResult = DigestUtils.sha1Hex(params[0]+params[1] + params[2]);
//校验签名
if(!signatureResult.equals(signature)) {
throw new RuntimeException("signature is not the same wechat signature is " + signature + " signatureResult is " + signatureResult);
}
return echostr;
}
}
