Consuming REST API with Java

由 牧云@^-^@ 提交于 2019-12-01 07:34:19
I have a management web application located on a remote server. This app was written using a MEAN stack and I have a list of all the RESTful routes necessary to connect to the web app. I am writing a Java client application that needs to send and receive data from this management app. How do connect the client to the web application if I have the server's IP address and REST routes? I imagine that I need to provide a URL connection to the server and the REST API file and then just call the route functions like PUT and GET . There are plenty of libraries to consume REST applications in Java

I'm running some project on MEAN.js and I've got a following problem. I want to make some user's profile calculation and the save it to database. But there's a problem with method in users model: UserSchema.pre('save', function(next) { if (this.password && this.password.length > 6) { this.salt = new Buffer(crypto.randomBytes(16).toString('base64'), 'base64'); this.password = this.hashPassword(this.password); } next(); }); If I will send a password with my changes, it will change credentials, so user is unable to login next time. I want to delete password from user object before save, but I'm
