我正在使用nodejs的mikeal'sawesomerequest模块。我还将它与express一起使用,在这里我将代理调用api以解决旧浏览器的cors问题:
app.use(function(request, response, next) {
var matches = request.url.match(/^\/API_ENDPOINT\/(.*)/),
method = request.method.toLowerCase(),
url;
if (matches) {
url = 'http://myapi.com' + matches[0];
return request.pipe(req[method](url)).pipe(response);
} else {
next();
}
});
在将
request
的响应发送回express
之前,是否有方法可以修改主体? 最佳答案
基于这个答案:Change response body before outputting in node.js我制作了一个在我自己的应用程序上使用的工作示例:
app.get("/example", function (req, resp) {
var write = concat(function(response) {
// Here you can modify the body
// As an example I am replacing . with spaces
if (response != undefined) {
response = response.toString().replace(/\./g, " ");
}
resp.end(response);
});
request.get(requestUrl)
.on('response',
function (response) {
//Here you can modify the headers
resp.writeHead(response.statusCode, response.headers);
}
).pipe(write);
});
欢迎任何改进,希望有帮助!
