400错误请求怎么解决
A 400 Bad Request Error occurs when a request sent to the website server is incorrect or corrupt, and the server receiving the request can’t understand it. Occasionally, the problem is on the website itself, and there’s not much you can do about that. But most of the time, the problem is one you might be able to solve—maybe you typed the address wrong, or maybe your browser cache is causing problems. Here are some solutions you can try.
当发送到⽹站服务器的请求不正确或损坏，并且接收到该请求的服务器⽆法理解时，就会发⽣400错误请求错误。 有时，问题出在⽹站本⾝上，您对此⽆能为⼒。 但是在⼤多数情况下，问题是您可能可以解决的问题-也许您输⼊的地址错误，或者浏览器缓存导致了问题。 您可以尝试以下解决⽅案。
什么是400错误请求错误？ (What Is a 400 Bad Request Error?)
A 400 Bad Request error happens when a server cannot understand a request that’s been made of it. It’s called a 400 error because that’s the HTTP status code that the web server uses to describe that kind of error.
当服务器⽆法理解对它的请求时，会发⽣400 Bad Request错误。 之所以称为400错误，是因为这是Web服务器⽤来描述这种错误的HTTP状态代码。
A 400 Bad Request error can happen because there’s a simple error in the request. Perhaps you’ve mistyped a URL and the server can’t return a , for some reason. Or maybe your web browser is trying to use an expired or invalid . Some servers that are not configured properly can also throw 400 errors instead of more helpful errors in some situations. For example, when you try to upload a file that’s too big to some sites, you might get a 400 error instead of an error letting you know about the maximum file size.
可能会发⽣400错误的请求错误，因为请求中有⼀个简单的错误。 也许您输⼊了错误的URL，并且服务器由于某种原因⽆法返回。 也许您的Web浏览器正在尝试使⽤过期或⽆效的 。 在某些情况下，某些未正确配置的服务器也可能引发400错误，⽽不是更多有⽤的错误。 例如，当您尝试上传对某些站
点太⼤的⽂件时，可能会显⽰400错误，⽽不是让您知道最⼤⽂件⼤⼩的错误。
Just like with  and , website designers can customize how a 400 error looks. So, you might see different looking 400 pages on different websites. Websites might also use slightly different names for this error. For example, you might see things like:
就像和，⽹站设计者可以⾃定义400错误的外观。 因此，您可能会在不同的⽹站上看到外观不同的400页。 ⽹站可能还会对此错误使⽤稍微不同的名称。 例如，您可能会看到以下内容：
400 Bad Request
400错误的要求
400 – Bad request. The request could not be understood by the server due to malformed syntax. The client should not repeat the request without modifications
400 –错误的请求。 由于语法格式错误，服务器⽆法理解该请求。 客户不得在未经修改的情况下重复请求
Bad Request – Invalid URL
错误的请求–⽆效的URL
Bad Request. Your browser sent a request that this server could not understand
错误的请求。 您的浏览器发送了此服务器⽆法理解的请求
HTTP Error 400. The request hostname is invalid
HTTP错误400。请求主机名⽆效
Bad Request: Error 400
错误的要求：错误400
HTTP Error 400 – Bad Request
HTTP错误400 –错误的请求
Often, you can do something to fix getting a 400 error, but figuring out exactly what can be challenging because of the vague nature of the error. Here are some things you can try.
通常，您可以采取⼀些措施来解决出现400错误的问题，但是由于错误的含糊性质，您可以准确地出可能具有挑战性的内容。 您可以尝试以下⽅法。
刷新页⾯ (Refresh the Page)
Refreshing the page is always worth a shot. Many times the 400 error is temporary, and a simple refresh might do the trick. Most browsers use the F5 key to refresh, and also provide a Refresh button somewhere on the address bar. It doesn’t fix the problem very often, but it takes just a second to try.
刷新页⾯始终值得⼀试。 很多时候，400错误是暂时的，只需刷新即可解决问题。 ⼤多数浏览器使⽤F5键刷新，并在地址栏上的某个位置提供“刷新”按钮。 它不会经常解决问题，但是只需⼀秒钟即可尝试。
仔细检查地址 (Double Check the Address)
The most common reason for a 400 error is a mistyped URL. If you typed a URL into your address box yourself, it’s possible you mistyped. If you clicked a link on another web page and were shown a 404 error, it’s also possible that the link was mistyped on the linking page. Check the address and see if you spot any obvious errors. Also, check for special symbols in the URL, especially ones that you don’t see in URLs often.
出现400错误的最常见原因是⽹址输⼊错误。 如果您⾃⼰在地址栏中输⼊了URL，则可能输⼊错误。 如果单击另⼀个⽹页上的链接并显⽰404错误，则也有可能在链接页⾯上键⼊了错误的链接。 检查地址，看看是否发现任何明显的错误。 另外，请检查URL中的特殊符号，尤其是您在URL中通常看不到的特殊符号。
执⾏搜索 (Perform a Search)
If the URL you are trying to reach is descriptive (or if you know roughly the name of the article or page you were expecting), you can use the keywords in the address to search the website. In the example below, you can’t really tell from the URL itself if anything is mistyped, but you can see some words from the name of the article.
如果您尝试访问的URL是描述性的(或者您⼤致了解所期望的⽂章或页⾯的名称)，则可以使⽤地址中的关键字搜索⽹站。 在下⾯的⽰例中，您⽆法真正从URL本⾝判断出是否输错了任何内容，但是可以从⽂章名称中看到⼀些单词。
Armed with that knowledge, you can perform a search on the website with the relevant keywords.
有了这些知识，您就可以使⽤相关的关键字在⽹站上进⾏搜索。
That should lead you to the correct page.
那应该引导您到正确的页⾯。
The same solution also works if the website you are trying to reach changed the URL for some reason and did not redirect the old address to the new one.
如果您尝试访问的⽹站由于某种原因更改了URL并且未将旧地址重定向到新地址，则相同的解决⽅案也可以使⽤。
And if the website you’re on doesn’t have it’s own search box, you can always use Google (or whatever search engine you prefer). Just use the “site:” operator to search only the website in question for the keywords.
⽽且，如果您所在的⽹站没有它⾃⼰的搜索框，则可以随时使⽤Google(或您喜欢的任何搜索引擎)。 只需使⽤“ site：”运算符即可仅在相关⽹站中搜索关键字。
In the image below, we’re using Google and the search phrase “site:howtogeek focal length” to search just the howtogeek site for the keywords.
在下图中，我们使⽤Google和搜索词组“ site：howtogeek焦距”来仅搜索howtogeek⽹站中的关键字。
清除浏览器的Cookie和缓存 (Clear Your Browser’s Cookies and Cache)
Many websites (including Google and YouTube) report a 400 error because the cookies they are reading are either corrupt or too old. Some browser extensions can also change your cookies and cause 400 errors. It’s also possible that your browser has cached a corrupt version of the page you’r
e trying to open.
许多⽹站(包括Google和YouTube)报告400错误，因为它们正在读取的Cookie损坏或过旧。 某些浏览器扩展程序也可能会更改Cookie，并导致400错误。 您的浏览器也可能缓存了您试图打开的页⾯的损坏版本。

To test out this possibility, you’ll have to clear your browser cache and cookies. Clearing the cache won’t affect your browsing experience much, but some websites may a take a couple of extra seconds to load as they re-download all the previously cached data. Clearing cookies means you’ll have to sign in again to most websites.
为了测试这种可能性，您必须清除浏览器缓存和cookie。 清除缓存不会对您的浏览体验造成太⼤影响，但是某些⽹站在重新下载所有先前缓存的数据时可能会花费额外的⼏秒钟时间。 清除Cookie意味着您将不得不再次登录⼤多数⽹站。
To clear the cache in your browser, you can follow which will teach you how to clear your cache on all the popular desktop and mobile browsers.
要清除浏览器中的缓存，您可以按照，将教您如何清除所有流⾏的台式机和移动浏览器上的缓存。
刷新您的DNS (Flush Your DNS)
Your computer might be storing outdated DNS records that are causing the errors. A simple flushing
of your DNS records might help solve the problem. It’s easy to do, and won’t cause any problems to try. We’ve got full guides on how to reset your DNS cache on both and .
您的计算机可能正在存储导致错误的过时DNS记录。 简单刷新DNS记录可能有助于解决问题。 这很容易做到，并且不会引起任何问题。我们已获得有关如何在和上重置DNS缓存的完整指南。
检查⽂件⼤⼩ (Check for File Size)
If you’re uploading a file to a website and that is when you are getting a 400 error, then the chances are that the file is too big. Try to upload a smaller file to confirm if this is causing the issue.
如果您正在将⽂件上传到⽹站，也就是当您遇到400错误时，则可能是⽂件太⼤。 尝试上传较⼩的⽂件，以确认是否是引起此问题的原因。
尝试其他⽹站 (Try Other Websites)
If you’ve been trying to open a single website and getting 400 errors, you should try to open other websites to see if the problem persists. If it does, it might be a problem with your computer or networking equipment rather than the website you’re trying to open.
如果您⼀直试图打开⼀个⽹站并遇到400个错误，则应尝试打开其他⽹站以查看问题是否仍然存在。 如果是这样，则可能是您的计算机或⽹络设备有问题，⽽不是您要打开的⽹站。
重新启动计算机和其他设备 (Restart Your Computer and Other Equipment)
This solution is a hit and miss, but restarting your computer and especially your networking equipment (routers, modems) is a common way to get rid of a lot of server errors.
该解决⽅案是⼀个偶然的选择，但是重新启动计算机，尤其是重新启动⽹络设备(路由器，调制解调器)是摆脱许多服务器错误的常⽤⽅法。联系⽹站 (Contact the Website)
If you’ve tried all the solutions and the error doesn’t seem to go away, then the website itself might be having a problem. Try to contact the website through a contact us page (if that works) or through social media. Chances are, they are already aware of the problem and working on fixing it.
如果您尝试了所有解决⽅案，但错误似乎并未消除，则⽹站本⾝可能有问题。 尝试通过“”页⾯(如果可⾏)或通过社交媒体与⽹站联系。 他们很可能已经意识到了这个问题，并正在努⼒解决。
