The things that have been connected to the pits by third parties for so many years ... About MD5 signature and SHA1 certificate of Pit

We often access third-party things, the most commonly used is a variety of logins, what QQ, Weibo and so on. Every time we access it we will find that they need MD5 signature or SHA1 certificate. Here is a big hole, many of the basic children's shoes are not enough to recruit, and then waste a lot of time on useless debugging above.

It is important to make it clear whether the official MD5 signature generation or Cygwin signature generation is based on the certificate of each of your apk certificates when using ant or Gradle packaging, and the certificate concept here refers to KeyStore, Each apk needs to have a certificate installed in the hardware environment, but the certificate we use when we debug is the auto-generated debug.keystore of our environment, and our formal release of the packaged certificate is the Xxxx.keystore we are actively generating. So we debug when the MD5 signature and release when the MD5 signature is not the same. So if you do not pass the verification of the signature once again, you will not be able to pull the third party's call successfully. The same applies to SHA1 certificates. So if you check the code countless times still can not find the reason, it is mostly MD5 signature and SHA1 certificate has not been replaced. You can re-generate a copy of your packaged xxxkeystore.

Follow the habit! Finally spit the trough a bit!!! You open the entrance of the third party!!! The TMD is not for the diversion amount?!!! What the hell can't you write a little bit of an open interface like a product?!!!!! We are giving you the flow!!! Soul Light!!! TX Open platform is 500 error!! The website is not even up!!! The next demo, I can't even run! Or a dependency package is missing! Or just not support as!!!. The most disgusting is the WX open platform Ah!!! Do not do anything to put it out!!! Open Guide Access process TMD is a piece of crap Ah!! Can you write with Dim sum!!! The monkey in a small company can't hurt it,!!!!!!. and BD map is the same AH!!! What a complicated thing to do!!! API write clearly not a bit?!!! By contrast, Ali is good. No problem with smooth access.
