公钥加密 openssl_public_encrypt(): key parameter is not a valid public key

公钥加密处理报错， openssl_public_encrypt(): key parameter is not a valid public key

1.开启open_ssl扩展

2.转化再加密

下载的公钥形式类似　　'-----BEGIN PUBLIC KEY----- MIGTDVGHWDFNADCBiQKBgQ99XZ6WiHxh94IAKTgSOEev 6tASj3XKVnssChGIZaSvdRXiJshGaR1LNeDbWSDFWE8OjA9sPlwgLJabnP WR283fGu7nRm9/sc4HKRETEF2bj7rcMeEAQAB -----END PUBLIC KEY-----'

去掉 、/，

$str = str_replace(array(" ", " ", " "), "", $str);

$this->public_key = 'MIGTDVGHWDFNADCBiQKBgQ99XZ6WiHxh94IAKTgSOEev6tASj3XKVnssChGIZaSvdRXiJshGaR1LNeDbWSDFWE8OjA9sPlwgLJabnPWR283fGu7nRm9sc4HKRETEF2bj7rcMeEAQAB';

再重新拼接  "-----BEGIN PUBLIC KEY----- " . wordwrap($this->public_key, 64, " ", true) . " -----END PUBLIC KEY-----"用来加密
