我正在尝试使用POST方法将数据插入到表中,因为我有一个角度服务函数
angular.module("productCategoryModule")
.factory("productCategoryService",productCategoryService);
productCategoryService.$inject = ['$http'];
function productCategoryService($http){
return {
createProductCategory:function(productCategory){
console.log("createProductCategory in service called",productCategory);
return $http.post('/api/createProductCategory',
{
categoryName:productCategory.categoryName,
details:productCategory.categoryDetails
}
);
},
getAllProductCategories:function(){
return $http.get('/api/getAllProductCategory');
}
}
}
在服务器端我有
function productCategoryRouteConfig(app){
this.app = app;
this.routeTable = [];
this.init();
}
productCategoryRouteConfig.prototype.init = function(){
var self = this;
this.addRoutes();
this.processRoutes();
}
productCategoryRouteConfig.prototype.processRoutes = function(){
var self = this;
self.routeTable.forEach(function(route){
if(route.requestType == 'get'){
//console.log("requestType",route.requestType)
self.app.get(route.requestUrl,route.callbackFunction);
} else if(route.requestType == 'post'){
//console.log("requestType",route.requestType);
self.app.post(route.requestUrl,route.callbackFunction);
} else if(route.requestType == 'delete'){
}
});
}
productCategoryRouteConfig.prototype.addRoutes = function(){
var self = this;
self.routeTable.push({
requestType: 'get',
requestUrl: '/createProductCategory',
callbackFunction: function(req, res){
res.render('createProductCategory',{title:'Create Product Category'});
}
});
self.routeTable.push({
requestType: 'post',
requestUrl: '/api/createProductCategory',
callbackFunction: function(req, res){
console.log("Post called");
//res.render('createProductCategory');
console.log("req.body",req.body);
var productCategoryDb = require('../database/productCategoryDb');
// console.log("productCategoryDb post",productCategoryDb);
// console.log("hello from createProductCategory post");
// console.log("req.body",req.body);
// productCategoryDb.productCategoryDb.createProductCategory(req.body, function(status){
// if(status)
// res.json(status);
// console.log(status);
// });
}
});
self.routeTable.push({
requestType: 'get',
requestUrl: '/viewProductCategory',
callbackFunction: function(req, res){
res.render('viewProductCategory',{title:'View Product Category'});
}
});
self.routeTable.push({
requestType: 'get',
requestUrl: '/api/getAllProductCategory',
callbackFunction: function(req, res){
console.log("hello from getAllProductCategory");
var productCategoryDb = require('../database/productCategoryDb');
console.log("productCategoryDb",productCategoryDb);
// productCategoryDb.productCategoryDb.getAllProductCategories(
// function (productCategories){
// console.log("productCategories",productCategories);
// res.json({productCategories : productCategories});
// }
// );
}
});
}
module.exports = productCategoryRouteConfig;
当我点击客户端的按钮时,我收到此错误
POST http://localhost:3000/api/createProductCategory 500(内部服务器错误)
我正在使用Node express mysql和angular。
我的数据库文件夹中有三个文件。
1.connectionString.js
var mysqlConnectionString = {
connectionString:{
host:'localhost',
user:'root',
password:'root',
database:'vidzy'
}
}
//module.exports = mysqlConnectionString;
exports.mysqlConnectionString = mysqlConnectionString;
2.connection.js
var mysql = require('mysql');
var mysqlConnectionString = require('/home/ep-3/node-express/yt_tutorial/database/connectionString.js');
var connectionStringProvider = {
getSqlConnection:function(){
var connection = mysql.createConnection(mysqlConnectionString.mysqlConnectionString.connectionString);
connection.connect(function(err){
if(err){
throw err;
} else{
console.log("connection was successful");
}
});
return connection;
},
closeSqlConnection:function(currentConnection){
currentConnection.end(function(err){
if(err){
throw err;
} else{
console.log("Disconnected");
}
})
}
}
exports.connectionStringProvider = connectionStringProvider;
3.productCategoryDb.js
var connectionProvider = require('/home/ep-3/node-express/yt_tutorial/database/connection.js');
var productCategoryDb = {
createProductCategory : function(productCategory, onSuccessful){
var insertStatement = 'INSERT INTO productcategory SET?';
var category = {
categoryName : productCategory.categoryName,
Details : productCategory.details,
isValid : productCategory.isValid,
CreatedDate : new Date()
}
var connection = connectionProvider.connectionStringProvider.getSqlConnection();
if(connection){
connection.query(insertStatement, category, function(err, result){
if(err){
console.log(err);
}
onSuccessful({status : 'Successful'});
console.log(result);
});
connectionProvider.connectionStringProvider.closeSqlConnection(connection);
}
},
getAllProductCategory : function(callback){
var connection = connectionProvider.connectionStringProvider.getSqlConnection();
var selectStatement = 'SELECT * FROM productcategory';
if(connection){
connection.query(selectStatement, function(err, rows, fields){
if(err){ through err; }
console.log(rows);
callback(rows);
});
}
}
}
exports.productCategoryDb = productCategoryDb;

您确定已加入模块body-parser
。
您在此处发布的代码似乎与我一直关注的教程相同。
您的代码似乎没问题,但我不知道app.js
中的代码是什么样的。
我已经确认当我注释掉模块undefined
时,我将 req.body 的控制台响应设为body-parser
。

我遇到了同样的错误,但在我的情况下,有一个节点模块功能,它为我所做的每个POST增加ID,而我忘记在DTO中添加ID。也许这不是您的情况,因为您正在使用mysql,但无论如何我都会发布答案,也许some1将通过此帮助解决他的错误
