Ara*_*oca 6 base64 mongodb node.js angularjs meanjs
我正在使用MEAN.JS框架(MongoDB,ExpressJS,AngularJS和NodeJS).
在frontEnd中使用AngularJS ; 我在一个字段中有一个带有base64编码图像的JSON.
我正在使用RESTful:
控制器:
var article = new Articles ($scope.article);
article.$save(function(response) {
//If all is OK
}, function(errorResponse) {
//Error
});

$scope.article
有一个名为" image " ($ scope.article.image)的字段,其中包含图像的base64字符串.
服务:
(function() {
'use strict';
angular
.module('articles')
.factory('articles', ['$resource',
function($resource) {
return $resource('articles/:articleId', { articleId: '@_id'
}, {
update: {
method: 'PUT'
}
});
}
]);})();

如果JSON在一个字段中没有任何Base64图像工作正常...
但...
如果我们在字段中添加Image的Base64字符串,则服务器响应会显示以下错误:

假设请求实体太大 ......图像大小为84Kb !!!!!
(我尝试使用$ http资源并发生相同的...)
相关答案:
我试图这样做,但不工作,不明白:
app.use(bodyParser.urlencoded({limit: '50mb'}));
app.use(bodyParser.json({limit: '50mb'}));

不推荐使用bodyParser,Base64图像的大小为84kb !!!!!
谢谢!!
尝试使用:
var express = require('express');
var app = express();
var busboy = require('connect-busboy');
app.post("/url_path",
busboy({
limits: {
fileSize: 10 * 1024 * 1024
}
}),
function(req, res, next) {
// check that the request's body was as expected
if (!req.busboy) return next('route'); // or next(new Error('...'));
// ...
});
