Q1:炸群代码


1、 404错误页面的作用是什么

我们的网站会有一些页面被搜索引擎收录但是后来我们将其删除的可能,同样也有可能用户手动输入我们网站的某个页面时出现拼写错误,这样就导致了有许多链接打开后没有对应的页面。404错误页面的作用就是当打开这种不存在的链接页面时跑出来告诉大家:“对不起,您访问的页面不存在!”同时,也是最重要的就是它还会返回出http状态码404,以告知搜索引擎该页面不存在!

简而言之,404错误页面的作用就是告诉用户及搜索引擎该页面不存在!

2、 查询404错误页面的返回状态码

回到刚刚的操作上,当我看到自己的404页面能显示后,我通过IE9进行了状态码的测试(具体操作就不细说了,大家也可以通过该网址检查状态码)。测试出来以后,我都懵了!返回状态码竟然是200。

404错误页面的状态码是200后果很严重

前面我也谈到404错误页面的作用了;然而,当页面返回码是404的时候表示该页面不存在,当状态码是200的时候表示该页面正常。想到这里就已经很恐怖了…

如果网站的自定义404错误页面在url无效时不返回“404”状态码而代之以“200”,搜索引擎会认为这个“根本不存在的”网页在网站内是存在的。

举例来说是两个并不存在的页面,如果搜索引擎得到的回应状态码是“200”,那么,便会将其收录到索引数据库,这样的结果便是这两个不同的url具有完全相同的内容:自定义404错误页面的内容。

站内不同页面重复文本的现象对许多搜索引擎而言都是大忌。更何况网站中不可能只有两个无效链接(不管是站内还是站外总会不可避免的出现比如拼写错误这样的情况),类似的重复内容会更多。这种情况会导致搜索引擎很难信任该站,会停止收录,并且降权,严重的还会K站。

更正404错误页面的状态码的方法

关于怎么更正404错误页面的状态码,网上也有查到一些解决办法,即通过代码申明该页面是404错误页面。可惜的是A服务器提供商虚拟空间所自定义的404页面是静态的htm页面,无法识别该类申明代码。

观察日本军事动向,法国学者语出惊人

    观察日China has set 2020 as the target year to complete the building of a "moderately prosperous society," which requires the eradication of poverty

    本军事The article explained how British photographer, Thomas Child, who had moved to China as an engineer, captured marriage ceremonies during the late Qing dynasty - which spanned from 1644 to 1912法国学"The display of Child's work at the China Exchange, an organization in London, was the first time US-based collector, Stephan Loewentheil, had shared the original images of life during the Qing dynasty in Peking, now known as Beijing

    观察日本军事动向,法国学者语出惊人

    语出"The family rose in importance in Shanghai from the late Qing dynasty into the twentieth century and went through more than 70 years of ups and downs until 1950," he said惊人While Watt's reaction to the never-before-seen photographs was by far the most compelling, the exhibition in Soho's Gerrard Street attracted worldwide attention, making headlines in the UK, the US, Europe and China观察日"The success of the show reflected the increasing global interest in China's people and culture, as well as the interest of the people of China in preserving and studying their own history," said Loewentheil, who's Historical Photography of China Collection is the largest holding of late Qing dynasty photographs of China in private hands本军事"My great, great grandfather was Zeng Guofan," Watt said法国学The 79-year-old never expected when he was browsing the internet that day that he would uncover a piece of family history dating back some 140 years

    语出"It was a picture I had never seen before and my instinct told me that the subjects could be my great grandparents," he told China Daily惊人According to Watt, the unique wedding photograph documents the moment of the start of the prominent Nie family in China观察日And she was the first South Korean citizen to gain permanent residency in China in 2006

    本军事"Now I often accompany Hefei officials to South Korea for business recruitment and students for educational exchanges," Cho said法国学In recent years, I have received numerous awards from the Chinese government语出I believe that in the coming five years, the gap between coastal and inland regions will be narrowed惊人"My husband and I came to China - to Hefei - to fulfill my elder son's dream

    In 2000, with Cho's help, the Banyang Elementary School - in which she had studied - began teaching ChineseCho's brothers and sisters also brought their children to Hefei

    观察日本军事动向,法国学者语出惊人

    cn  Cho Sung-hye talks with her students at Hefei University in Anhui provinceA remarkable South Korean teacher took up residence in Hefei, Anhui province, at the urging of her young son and never looked backWhat do you think China will be like in five years' time? How do you view China's longer-term future? Chinese people's incomes have increased significantly in recent years and they will become richer in the next five yearsHe has been trying his best to achieve what he has vowed to do

    To better promote the educational exchanges, Cho and her husband founded the Handa Cultural Exchange Co in Hefei in 2006, with Cho as presidentShe has played a prominent role in education, business development and friendshipOpening up to the world has brought dramatic changes to the coastal regions, which have been more developed that the inland areas" What do you feel has been China's biggest achievement over the past five years? What's the most notable change you've observed? China has achieved much in many aspects over the last five years

    In 1998, when she was back in her hometown, Cho delivered a three-hour speech to 82 heads of primary schools, trying to persuade them to offer Chinese coursesIn 2010, she was listed as one of the most influential women of the century in Hefei

    观察日本军事动向,法国学者语出惊人

    Officials should all start from basic positions and get promotions graduallyHalf a year later, Park returned to Hefei University and has been there ever since

    "In the early years, transportation between Hefei and South Korea was not convenient"In the five years since the 18th CPC National Congress in 2012, China has invested more than ever before in poverty relief, and President Xi Jinping has vowed to eliminate poverty by 2020," Cho notedSome of the South Korean companies based in the two zones, the largest in the province, were attracted through Cho's effortsThe boy - a great fan of Chinese history who was able to give the names of more than 900 figures in the Chinese classic Romance of Three Kingdoms - was inspired and wanted very much to follow the suggestionDo you believe that some of China's experiences or practices could be used to solve pressing global problems? If so, what are they? China has a very mature and comprehensive system to foster leadershipWhat three words would you use to describe China today? Revitalizing, changing, confident

    Cho said the number of the poverty-stricken students is declining, and they can now get more financial support from the government, rather than relying on occasional social donationsIt's hard to make long-term predictions, but I hope China can keep its own development pace and have its own development patterns

    China is a big country, so officials have to collaborate with each other well" Cho and her husband have also donated hundreds of thousands of yuan to help prevent the children of poverty-stricken rural families in Anhui from dropping out of school

    Also, Xi has been very good at choosing the right people to work with himI became the first South Korean person to receive the Chinese Central Government's Friendship Award in 2002 and the first from my country to get permanent residency in China in 2006

    She herself knew little of the province or its capital at that time, so she decided to have a look before taking her family there"On the visit to Hefei, I found it was not very developed but thought it would have great potentialFor the last five years, the air has been clearing up"I told him that we had just started here and we should at least spend five years in the city before judging whether we should move to another place," Cho said

    First, China is playing an increasingly important role in the world, so some neighboring countries, and especially some developed Western countries may regard China as a challenger to the power they have maintained for many yearsSome of China's practices are also worth learning, such as how it trains its officials

    She is now helping the development area build a China-South Korea Industry Park, and she has already brought in three South Korean companies to invest in the city's high-tech zoneWhat is your impression of President Xi Jinping? I think he is a determined man

    After finishing middle school and high school studies in the city, Cho's elder son was admitted to Peking University for undergraduate studies, and then returned to Hefei later for his MBA at the University of Science and Technology of ChinaThe Obama administration had done everything it could to internationalize the South China Sea issue and had used the Philippines, a US ally, to advance the American strategy

    However, the Pew survey finds that Duterte and his policies are widely popular at home despite concerns expressed by some governments, in particular the US, over Duterte's clashes with drug cartels and alleged human rights violationsA quarter now name China as the world's leading economy, up from 14 percent the last time the Philippines was surveyedAt the same time, 78 percent believe the current economic situation is good, and 57 percent are satisfied with the direction of the country, a 21 percentage-point increase from 2014, the last time this question was asked in the PhilippinesAnd despite the Philippines being the most pro-Trump nation in Pew's spring 37-country survey, confidence in Trump now is lower than it was in then-President Barack Obama in 2015

    The Philippines under Duterte has tried to develop an independent foreign policy rather than being a US puppet most of the timeSince becoming Philippines president in June 2016, Rodrigo Duterte has refused to be used by the US to advance its strategy

    That was certainly not the policy under Obama when he launched the US pivot-to-Asia policy, trying to gang up US allies on ChinaAnd on global economic status, about half of Filipinos (49 percent) say that the US is still the leading economic power, but that is down from 66 percent who said so in 2015

    The survey released on Sept 21 bore a title saying people in the Philippines still favor the United States over China, but that the gap is narrowingThis represents a dramatic shift since that question was last asked in 2015
