Avoiding getting banned crawling web

  • rotate your user agent from a pool of well-known ones from browsers (google around to get a list of them)
  • disable cookies as some sites may use cookies to spot bot behaviour
  • use download delays (2 or higher).
  • if possible, use Google cache to fetch pages, instead of hitting the sites directly
  • use a pool of rotating IPs. For example, the free Tor project or paid services like ProxyMesh. An open source alternative is scrapoxy, a super proxy that you can attach your own proxies to.
  • use a highly distributed downloader that circumvents bans internally, so you can just focus on parsing clean pages.

In this section we implement the login interface for Larabbs small programs

 

In the third tutorial, we’ve added the interface for mobile registration and WeChat login, so Larabbs can use:
Mailbox
Cell phone
WeChat Login Sign in in in three ways.

As mentioned in the previous section, if the public platform is bound to other WeChat applications and small programs, then UnionId can be used to get the only WeChat user, but because we do not have a real WeChat mobile phone app or web application, so do not discuss.

The scenario for a small program to log on is:
Failure to find a user who is bound by the openid of the eprogram jumps to the login page, asks the user to enter the user name (mailbox or phone) and password, and then binds the user to the e-program openid, returning to access-token, and the login is successful. You can find the bound user based on the openid of the esmalle, return directly to access-token, and log on successfully.

WordPress post link not found

One of the most common phenomena is that the initial fixed link is not set up and the fixed link needs to be re-modified to allow the article to be accessed. No additional action is required.    Many cloud platforms are problematic at the beginning of the setup and need to reset the fixed link when using it. Modify method: Select your fixed link structure. In the settings → fixed link, you can select the default format, or you can use the structure label to enter the format you want in the input box of the custom structure. So that each address corresponds to a unique blog. For performance reasons, it is not recommended to use blog types, blog tags, bloggers, blog titles as the beginning of fixed link addresses, which are plain Text properties (field), using them as the beginning of the link, WordPress needs more time to distinguish between article addresses and pages (page) Address, and in order to distinguish between additional information to be stored in the database, it slows down the opening of the article. If you are just using WordPress and there is a phenomenon that the article cannot access, it is most likely because there is a problem with WordPress’s fixed link.
