我有一个服务器，可以发送任何大小的响应 . 当我拨打响应大小为1MB的电话时，WSO2 api manger工作正常 . （每分钟1000个请求）当我们进行响应大小为10MB的相同调用时，WSO2 api管理器最初会减小响应的大小，最终变为0大小的响应 . 每分钟有1000个请求，只有前28个请求响应，其他10MB请求响应较小 . 我尝试直接使用10MB响应大小来命令后端服务，所有响应都是10MB .

这是我的server.js（为nodejs编写）

var http = require("http");
var url  = require('url');

var server = http.createServer(function(request, response) {
        var params = url.parse(request.url, true).query;
        var size = parseInt(params.size);
        var buffer = new Buffer(size);
        buffer.fill("a");
        response.write(buffer.toString());
        response.end();
});

server.listen(8083);
console.log("Server is listening");

WSO2使用参数大小命中此服务器 .

我的直接http电话看起来像

wget http://A.B.C.D:8083/?size=10485760

我的WSO2电话看起来像

wget --header="Authorization: Bearer Xobzt7lefiMadwt4u4Vp9q93dR8a" -qO- http://E.F.G.H:8280/loadtest/1.0/?size=10485760
