MEANJS:413(请求实体过大) [英] MEANJS : 413 (Request Entity Too Large)
问题描述
我使用的是MEANJS栈,我使用 NG流上传图片并保存imgsrc为base64网址。
数据:图像/ PNG; BASE64,iVBORw0KGgoAAAANSUhEUgAAARkAAACzCAYAAAC94GgrA ....
下面是我的猫鼬的模式:
VAR ServiceSchema =新mongoose.Schema({
名称:字符串,
网址:字符串,
描述:字符串,
类别:字符串,
imgsrc:字符串
});
我为大图像碰上了请求实体过大服务器错误。
我可以调整在上传之前的形象,但是这仍然只允许我大小的图像200×200
$ scope.resizeimageforupload =功能(IMG){
VAR帆布=的document.getElementById('画布'); VAR MAX_WIDTH = 200; // 400;过大仍然
VAR MAX_HEIGHT = 200; // 300过大仍然
VAR WIDTH = img.width;
VAR HEIGHT = img.height; 如果(宽>高度){
如果(宽> MAX_WIDTH){
高* = MAX_WIDTH /宽度;
宽度= MAX_WIDTH;
}
}其他{
如果(高度> MAX_HEIGHT){
宽* = MAX_HEIGHT /高度;
高度= MAX_HEIGHT;
}
}
canvas.width =宽度;
canvas.height =高度;
变种CTX = canvas.getContext(2D);
ctx.drawImage(IMG,0,0,宽度,高度); VAR dataURL = canvas.toDataURL(图像/ PNG);
dataURL.replace(/ ^数据:影像\\ /(PNG | JPG)的base64,/,); 返回dataURL;
};
周围或替代的解决方案上的工作任何想法?

您可以添加以下内容前preSS配置:
app.use(bodyParser.urlen codeD({限制:'50MB'}));
app.use(bodyParser.json({限制:'50MB'}));
基本上你需要配置防爆preSS Web服务器接受请求,大大小。你要接受任何MAXSIZE替换 50MB
。
希望这有助于!
I am using a MEANJS stack, I upload an image using ng-flow and save the imgsrc as base64 url.
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAARkAAACzCAYAAAC94GgrA....
Here is my mongoose schema:
var ServiceSchema = new mongoose.Schema({
name : String,
url: String,
description : String,
category : String,
imgsrc: String
});
I run into a Request Entity Too Large server error for large images.
I could resize the image prior to upload but this still only allows me image of size 200 x 200
$scope.resizeimageforupload = function(img){
var canvas = document.getElementById('canvas');
var MAX_WIDTH = 200; //400; too big still
var MAX_HEIGHT = 200; //300 too big still
var width = img.width;
var height = img.height;
if (width > height) {
if (width > MAX_WIDTH) {
height *= MAX_WIDTH / width;
width = MAX_WIDTH;
}
} else {
if (height > MAX_HEIGHT) {
width *= MAX_HEIGHT / height;
height = MAX_HEIGHT;
}
}
canvas.width = width;
canvas.height = height;
var ctx = canvas.getContext("2d");
ctx.drawImage(img, 0, 0, width, height);
var dataURL = canvas.toDataURL("image/png");
dataURL.replace(/^data:image\/(png|jpg);base64,/, "");
return dataURL;
};
Any ideas on a work around or alternate solution ?

You can add following to express config:
app.use(bodyParser.urlencoded({limit: '50mb'}));
app.use(bodyParser.json({limit: '50mb'}));
Basically you need to configure Express webserver to accept bigger request size. Replace 50mb
with whatever maxsize you want to accept.
Hope this helps!!!
