Curl POST to HTTPS url gives SSLRead() error:curl: (56) SSLRead() return error -9806

2015-09-22 10:26 519 查看
当系统升级到OSX 10.10.3的时候，用brew更新软件安装包，出现了curl抛出的错误。
==> Upgrading boost
==> Downloading https://homebrew.bintray.com/bottles/boost-1.58.0.yosemite.bottle.tar.gz 0.7%
curl: (56) SSLRead() return error -9806
Error: Failed to download resource "boost"
起初，以为是宽带的问题，据说某宽带在使用过程中老是插入广告，竟连curl抓取数据包都难免植入广告。如果是宽带的问题，应该说curl获取一切信息都会出错，经尝试，对于http协议的请求都是fine的，那么尝试https协议，发现github也是好的，可以收到数据。但是，一旦请求的https的具体的某一个包的时候，出现curl（56）错误：
error:curl: (56) SSLRead() return error -9806
查询得知：curl（56）错误是----CURL_RECV_ERROR:Failure with receiving network data.意思很明确了：curl接收网络数据失败。最后的最后，只能从网上获取答案：很幸运，有人比我早遇到此类问题：在stackoverflow上有篇名为《osx 10.10 Curl POST to HTTPS url gives SSLRead() error》I just recently upgraded to OSX 10.10 Yosemite and I since the upgrade I can't do Curl POST to a SSL url anymore.I first used wordpress' wp_remote_request call and also tried to use curl in php.Both (as expected) give the same error message:Error Number:56Error String:SSLRead() return error -9806Note: when I curl POST to HTTP it works fine.I reckon it is a setting in PHP.ini or in my apache (I lost my original HTTPD.conf file after upgrade...).Can anyone help me out?这是被采取的答案：
I've seen this error happen when php is compiled with a version of cURL that usesApple's Secure Transport under Yosemiteand the target of the URL request doesn't support SSLv3 (which was probably disabled due to thePOODLE vulnerability). Whatis the output of this command?
$ php -i | grep "SSL Version"
I suspect you'll see this:
SSL Version => SecureTransport
You can overcome this by installing a version of php which uses a version of cURL which uses OpenSSL instead of SecureTransport. This is most easily done withhomebrew. So install that first ifyou don't already have it. If homebrew is installed but you haven't run
brew update
since upgrading to Yosemite, do that first. Also make sure you've installed XCode >= 6.1 and the latest XCode command line tools.
brew doctor
will tellyou if you've done it all right.Add the Homebrew taps below that you will need in order to get brewed php installed. Skip this step if these repos are already tapped. If you're unsure if these repos are already tapped, just run the commands below. Worst case scenario, you'll get a harmless
Warning:
Already tapped!
$ brew tap homebrew/dupes
$ brew tap homebrew/versions
$ brew tap homebrew/php
Then install curl with openssl:
$ brew install --with-openssl curl
Then install php using the curl you just installed and brewed openssl:
$ brew install \
--with-apache \
--with-homebrew-curl \
--with-homebrew-openssl \
--without-snmp php55
if you're running nginx change 
--with-apache
to 
--with-fpm
.the 
--without-snmp
is necessary because ofissue #1311.if using apache, make sure to add 
LoadModule php5_module /usr/local/opt/php55/libexec/apache2/libphp5.so
to your
/etc/apache2/httpd.conf
and restart apache.Install any php extensions you're going to need eg. 
mcrypt
.
$ brew install php55-mcrypt
After you're done, run this again:
$ php -i | grep "SSL Version"
And you should see:
SSL Version => OpenSSL/1.0.1j
And now, re-test your application and the 
SSLRead() return error -9806
should go away.大概意思：先使用命令php -i |grep "SSL Version"看看SSL Version的信息，猜想你看到是：
SSL Version => SecureTransport
那么，就可以按照下面的命令去做：
$ brew tap homebrew/dupes
$ brew tap homebrew/versions
$ brew tap homebrew/php
有可能会出现不伤大雅的警告信息：
Already tapped!
重点来了：
然后使用openssl安装curl，这就是要替换掉原来的curl，命令如下：
[code]$ brew install --with-openssl curl
[/code]
然后使用刚才安装的curl和openssl安装php：
$ brew install \
--with-apache \
--with-homebrew-curl \
--with-homebrew-openssl \
--without-snmp php55
如果你想运行nginx，将 
--with-apache
 
改为--with-fpm
.因为 issue #1311的缘故，
--without-snmp是必须
.如果使用apache，确保添加 
LoadModule php5_module /usr/local/opt/php55/libexec/apache2/libphp5.so到
/etc/apache2/httpd.conf
并重启apache.安装你需要的php的其他扩展，例如 ： 
mcrypt
.
$ brew install php55-mcrypt
完成后，再次运行下面的命令：
$ php -i | grep "SSL Version"
你会看到：
SSL Version => OpenSSL/1.0.1j
好吧，这个问题就这样解决了。
