我试图使用本教程设置Google Recaptcha(https://codeforgeek.com/2016/03/google-recaptcha-node-js-tutorial/),并将recaptcha代码移入它自己的模块中。我得到:res.json不是Node.js模块中的函数
TypeError: res.json is not a function在控制台
当我尝试这种代码:
var checkRecaptcha = function(req, res){
// g-recaptcha-response is the key that browser will generate upon form submit.
// if its blank or null means user has not selected the captcha, so return the error.
if(req.body['g-recaptcha-response'] === undefined || req.body['g-recaptcha-response'] === '' || req.body['g-recaptcha-response'] === null) {
return res.json({"responseCode" : 1,"responseDesc" : "Please select captcha"});
}
// Put your secret key here.
var secretKey = "************";
// req.connection.remoteAddress will provide IP address of connected user.
var verificationUrl = "https://www.google.com/recaptcha/api/siteverify?secret=" + secretKey + "&response=" + req.body['g-recaptcha-response'] + "&remoteip=" + req.connection.remoteAddress;
// Hitting GET request to the URL, Google will respond with success or error scenario.
var request = require('request');
request(verificationUrl,function(error,response,body) {
body = JSON.parse(body);
// Success will be true or false depending upon captcha validation.
if(body.success !== undefined && !body.success) {
return res.json({"responseCode" : 1,"responseDesc" : "Failed captcha verification"});
}
return res.json({"responseCode" : 0,"responseDesc" : "Sucess"});
});
}
module.exports = {checkRecaptcha};
为什么会出现这种情况?我确实在我的app.js中设置了app.use(bodyParser.json());
,res.json()
似乎在我的应用的其他部分中正常工作,而不是此recaptcha模块。
你如何使用/包括您所展示的模块/中间件? (另外,'bodyParser.json()'用于*解析* JSON请求,而不是发送JSON响应) – mscdex
是否有一个特定的行,你会得到错误? – jonathanGB
@jonathanGB我得到第7,23和25行的错误(这取决于google的recaptcha响应)。 –
