在尝试wikipedia查询时CURLPP 400坏请求
提问于 2015-09-11 11:19:18
我希望使用以下URL提取维基百科页面的摘要：
https://en.wikipedia.org/w/api.php?format=json&action=query&prop=extracts&exintro=&explaintext=&titles=Stack%20Overflow我还利用CURLPP图书馆来实现这一目标：
#include <curlpp/cURLpp.hpp>
#include <curlpp/Easy.hpp>
#include <curlpp/Options.hpp>
#include <curlpp/Exception.hpp>
#include <sstream>
#include <fstream>
#include <iostream>
using namespace std;
int main()
{
string query = "Aldous Huxley";
curlpp::Cleanup myCleanup;
std::ostringstream os;
string url = "https://en.wikipedia.org/w/api.php?format=xml&action=query&prop=extracts&exintro=&explaintext=&titles=";
os << curlpp::options::Url(std::string( url + query));
string asAskedInQuestion = os.str();
cout << asAskedInQuestion << endl;
return 0;
}输出
每次尝试查询Aldous Huxley时，我都会得到以下错误：
<html>
<head><title>400 Bad Request</title></head>
<body bgcolor="white">
<center><h1>400 Bad Request</h1></center>
<hr><center>nginx/1.9.4</center>
</body>
</html>任何其他查询都正常工作。我为什么要犯这个错误？例如，当我尝试无政府主义时，我得到以下输出：
<api batchcomplete="">
<query>
<pages>
<page _idx="12" pageid="12" ns="0" title="Anarchism">
<extract xml:space="preserve">
Anarchism is a political philosophy that advocates stateless societies often defined as self-governed voluntary institutions, but that several authors have defined as more specific institutions based on non-hierarchical free associations. Anarchism holds the state to be undesirable, unnecessary, or harmful. While anti-statism is central, anarchism entails opposing authority or hierarchical organisation in the conduct of human relations, including, but not limited to, the state system. As an anti-dogmatic philosophy, anarchism draws on many currents of thought and strategy. Anarchism does not offer a fixed body of doctrine from a single particular world view, instead fluxing and flowing as a philosophy. There are many types and traditions of anarchism, not all of which are mutually exclusive. Anarchist schools of thought can differ fundamentally, supporting anything from extreme individualism to complete collectivism. Strains of anarchism have often been divided into the categories of social and individualist anarchism or similar dual classifications. Anarchism is usually considered a radical left-wing ideology, and much of anarchist economics and anarchist legal philosophy reflect anti-authoritarian interpretations of communism, collectivism, syndicalism, mutualism, or participatory economics.

您需要对查询字符串进行URL编码。使用，例如。
string query = "Aldous%20Huxley";页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
