C++ libcurl http response code issues

问题 这个问题/怪癖/副作用让我发疯。 在代码底部附近,HTTP 交互的响应代码通过引用传递到 responseCode_。 然而,即使该站点可以以其他方式访问,它也经常显示为 0,并且返回太快而无法超时...... 所有变量都已定义,下面的代码只是类中 C++ 方法的片段。 任何 var_ 变量都是基于实例的。 它在多个线程上运行,但这应该不是问题。 每个使用 libcurl 的类在各自的线程上都有自己的实例。 提前感谢您的任何想法或建议... CURL *curl; curl = curl_easy_init(); //The URL curl_easy_setopt(curl, CURLOPT_URL, url.getURLString().c_str()); //Timeout curl_easy_setopt(curl, CURLOPT_TIMEOUT, &timeout_); //disable signals to use with threads curl_easy_setopt(curl, CURLOPT_NOSIGNAL, 1); //Redirecting curl_easy_setopt(curl, CURLOPT_MAXREDIRS, 5); curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1); /

Serving directory images using Express Js

问题 我有一个应用程序的简单用例; 用户可以将图片上传到服务器并存储在一个目录中,用户可以查看所有上传并存储在该目录中的图片。 第一个标准的功能正在运行,并且应用程序将上传的图像保存到图像目录中。 下一步是返回所有图像。 对于前端,我将使用某种图块库向用户呈现图像。 但是,我的问题与如何通过 express js 最好地将“所有图像”返回给最终用户有关。 本质上,我希望进行目录转储,但对如何执行此操作的优雅(阅读:任何!)解决方案感到困惑。 任何意见或建议最受赞赏。 编辑:澄清一下,路由应该在命中时返回所有图像。 由于未来的实现将根据某些标准过滤图像。 例子: // return the view page for register app.get('/gallery',function(req,res){ // return images here res.send(); }); 回答1 app.use('/images', express.static('path/to/images'))

Decoding the response body from azure functions

问题 我正在尝试天蓝色的功能。 我了解 azure 函数的工作原理以及将这些函数与其他 azure 服务相结合的必要绑定。 设想: 通过请求的主体将 JSON 发布到 azure 函数。 将 JSON 存储在 documentDB 中并返回与响应相同的 JSON。 在 azure 控制台中调用 api 时它可以正常工作。 它也适用于邮递员。 但奇怪的是,它在我的反应应用程序中不起作用。 问题: 在上图中,如您所见,响应是由 react 应用程序中的 azure 函数返回的。 但主体是一个ReadableStream对象。 还有一个锁定的财产。 我已经尝试过功能和匿名授权级别。 两者都给出了相同的结果。 我对这个问题感到困惑。 我的想法: 我应该有一个对象来读取流对象还是授权问题。 它在邮递员和 azure 控制台中运行良好,但在 react 应用程序中运行良好。 我错过了什么? 注册(POST)Azure 函数 此函数获取一些请求正文参数并使用输出绑定将其存储在 documentDB 中。 这是代码: module.exports = function(context, req) { context.log('Node.js HTTP trigger function processed a request. RequestUri=%s', req.originalUrl); if

Django rest framework add dict to serializer

问题 这是我的serializers.py: class SysUserSerializer(serializers.ModelSerializer): pk = serializers.IntegerField(read_only=True) login_id = serializers.CharField(required=False) name = serializers.CharField(required=False) class Meta: model = SysUser fields = ('pk','login_id','name') 这是我的views.py: class GetUserDetail(APIView): def get(self, request, format=None): sysuser = SysUser.objects.get(id=1) serializer = SysUserSerializer(sysuser) serializer.data['gender'] = 'male' # i don't think this line is working return Response(serializer.data, status=200) 但我得到了这个回应: {"pk": 1, "login_id": "john77",

How to use an API with opaque response?

I tried to use this Cat Facts API like so: const URL = "https://catfact.ninja/fact?limit=1" // In browser, this displays the JSON fetch(URL).then(response=> { console.log(response); return response.json(); } ); but I got Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://catfact.ninja/fact?limit=1. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). TypeError: NetworkError when attempting to fetch resource. so after trying with fetch(URL, {mode:'no-cors'}) .then(response=> { console.log(response); return response.json(); } ); I now

Change CloudFront response using lambda@Edge

I have been trying to use lambda@edge to add the CloudFront-viewer-country header to my response, I managed to trigger the function and its working, but I can't see any logs in cloudWatch, cloudWatch is only logging the test which is done on the function page not the real test that got trigged by visiting the website, I googled how to find the logs and found out that its in cloudWatch of the nearest region that received the request, but I could not find any. I have tried two methods to change my response one of them was on stack overflow answers: https://stackoverflow.com/questions/48633610

Disabling IIS Server Response Headers in Case of 404 and 302 Files

I use the following custom headers and rewrite rules to remove server response headers IIS 8.5 but when open the network monitor on Firefox or Chrome and point to any file with status 404 (as well as missing images) or 302 (as well as missing directory or requested file in aspxerrorpath redirection) enables me to see the original headers. For example Microsoft website is hiding this information and headers but visiting a URL like this will let me easily determine the server and IIS version which are: Server Microsoft-IIS/10.0 X-AspNet-Version 4.0.30319 X-Powered-By ASP.NET <system.webServer>

NodeJS SyntaxError: Unexpected token in JSON at position 0

The body of the response from Authorize.net's sandbox API is: { "messages": { "resultCode": "Error", "message": [ { "code": "E00012", "text": "You have submitted a duplicate of Subscription 5777085. A duplicate subscription will not be created." } ] } } but when I go to parse it: try { bodyObj = JSON.parse(body); } catch (ex) { console.error(ex); } I get this error: SyntaxError: Unexpected token in JSON at position 0 And this: console.log(response.headers['content-type']); returns this: application/json; charset=utf-8 What am I doing wrong? I want to parse the JSON into a JS object.
