使用Qt设置http get请求参数

本文介绍了使用Qt设置http get请求参数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在开发一个基本的应用程序在Qt使用REST API从Parse检索数据。我经历了一些类引用和cURL手册，但它仍然不清楚如何设置请求参数。例如，我想要验证用户。下面是Parse提供的curl示例：

curl -X GET \ -HX-Parse- -Id：myappid\ -HX-Parse-REST-API-Key：myapikey\ -G \ --data-urlencode'username = test' \ --data-urlencode'password = test'\ api.parse/1/login

我设置的url和头像这样

QUrl url api.parse/1/login）; QNetworkRequest request（url）; request.setRawHeader（X-Parse-Application-Id，myappid）; request.setRawHeader（X-Parse-REST-API-Key，myapikey）; nam-> get（request）;

当没有参数的时候工作得很好，但是我应该使用什么来实现和curl一样

解决方案

使用--data-urlencode切换？

<不幸的是，QUrl :: addQueryItem（）在qt5中被弃用，但是从那里开始我发现了QUrlQuery类，它有一个addQueryItem（）方法，并且可以产生一个查询字符串，它是QUrl的setQuery（）方法可以接受的，所以它现在看起来像这样和工作正常：

QUrl url（api.parse/1/login）; QUrlQuery查询; query.addQueryItem（username，test）; query.addQueryItem（password，test）; url.setQuery（query.query（））; QNetworkRequest request（url）; request.setRawHeader（X-Parse-Application-Id，myappid）; request.setRawHeader（X-Parse-REST-API-Key，myapikey）; nam-> get（request）;

感谢Chris的提示。

I'm developing a basic application in Qt that retrieves data from Parse using the REST API. I went through some class references and the cURL manual but it's still not clear how you set the request parameters. For example, I'd like to authenticate a user. Here's the curl example provided by Parse:

curl -X GET \ -H "X-Parse-Application-Id: myappid" \ -H "X-Parse-REST-API-Key: myapikey" \ -G \ --data-urlencode 'username=test' \ --data-urlencode 'password=test' \ api.parse/1/login

I set the url and the headers like this

QUrl url("api.parse/1/login"); QNetworkRequest request(url); request.setRawHeader("X-Parse-Application-Id", "myappid"); request.setRawHeader("X-Parse-REST-API-Key", "myapikey"); nam->get(request);

which worked fine when there were no parameters, but what should I use to achieve the same as curl does with the --data-urlencode switch?

Thanks for your time

解决方案

Unfortunately, QUrl::addQueryItem() is deprecated in qt5 but starting from there I found the QUrlQuery class which has an addQueryItem() method and can produce a query string that is acceptable for QUrl's setQuery() method so it now looks like this and works fine:

QUrl url("api.parse/1/login"); QUrlQuery query; query.addQueryItem("username", "test"); query.addQueryItem("password", "test"); url.setQuery(query.query()); QNetworkRequest request(url); request.setRawHeader("X-Parse-Application-Id", "myappid"); request.setRawHeader("X-Parse-REST-API-Key", "myapikey"); nam->get(request);

Thanks for the tip Chris.
