yar协议通过http调用，demo中的motan2使用后提示超出允许内存 #1

请描述下你是如何使用的？比如是 PHP Client 调用 Motan2 的服务吗？还是 调用 Yar 协议的服务？

JerryChaox commented 7 years ago

调用的是yar协议的服务 用motan2:// 提示超出允许内存 用http:// 调用提示找不到服务

motan2协议应该是php作为客户端调用了motan协议的端口，这块应该是我弄错了，接口那边没有暴露motan协议。 http协议：我用yarclient是能够请求成功的，不过遇到中文会出现解包错误，unpack error。所以想试一下这边这个组件，但是相同的url提示找不到服务

idevz commented 7 years ago

这个组件只可以调用 Motan2 协议的服务，另外你说的 http 协议的 yarclient 成功的那是 Yar 的服务端吧？是 Motan-Yar 导出的服务吗？ unpack error 是调用 Motan-Yar Server 报的错？还是 PHP-Yar Server ？

php的yarclient 调用 Motan-Yar Server. 没有中文的情况下是可以正常通信的

JerryChaox commented 7 years ago

$client = new Yar_Client("http://localhost:8003/api/merchant"); $result = $client->getMerchant(1);

@Yar(“api/merchant”) class MerchantService ｛ public Merchant getMerchant(int MerchantId); ｝

暴露 demoYar:8003 public Merchant getMerchant(int merchantId) { 数据库查询 }

class Merchant { int id; String name; //有中文的时候出现unpack error }

暴露为motan接口后提示异常：

目前php版本只能使用motan2协议与其他语言版本通信，java端必须也使用motan2协议

JerryChaox commented 7 years ago

motan2协议下出现以下异常：

{"errcode":10001,"errtype":1,"errmsg":"ProviderProtectedMessageRouter handler Error: provider not exist serviceKey=motan-demo-rpc/cn.tata.t2s.ssm.service.merchantService/1.0 requestId=-2620754180148297728 interface=cn.tata.t2s.ssm.service.merchantService method=getMerchant(null)"}

@JerryChaox Motan2 协议使用简单序列化来打包请求和响应，目前简单序列化只支持 3 种简单数据类型，请确认你上面 getMerchant 方法的参数是否正确？ 简单序列化文档地址 相关跨语言调用实例参考motan-examples
