我正在尝试使用 thrift 的 TFileTransport 包装要从 Python 调用的 Java 类。我尝试使用两种协议 TJSON 和 TBinary 但我不断收到此异常
org.apache.thrift.transport.TTransportException: FileTransport error: bad event size

这是我的 Python 客户端的外观:
def __init__(self):
self.outFile=open("../../ThriftFile.in","a")
self.transport = TTransport.TFileObjectTransport(self.outFile)
self.protocol = TJSONProtocol.TJSONProtocol(self.transport)
self.client = sendPyInterface.Client(self.protocol)
self.transport.open()
def send(self,routingKey, message):
self.transport.write(pickle.dumps(self.client.send_send(routingKey, message)))
def configClient(self,configurationDict):
self.transport.write(pickle.dumps(self.client.send_ClientConfig(configurationDict)))
if __name__ == "__main__":
SuroClient=SuroPyClient()
configurationDict={"ClientConfig.LB_TYPE":"static","ClientConfig.LB_SERVER":"localhost:7101"}
SuroClient.configClient(configurationDict)
SuroClient.send("routingKey", "testMessage")
这是我的服务器:
public static void startThriftServer(SendPyInterface.Processor processor) {
try {
File input = new File("src/main/java/com/netflix/suro/client/ThriftFile.in");
if(!input.exists()){
input.createNewFile();
}
File output = new File("src/main/java/com/netflix/suro/client/ThriftFile.out");
if(!output.exists()){
output.createNewFile();
}
TFileTransport inputFileTransport = new TFileTransport(input.getAbsolutePath(), true);
TFileTransport outputFileTransport = new TFileTransport(output.getAbsolutePath(), false);
System.out.println(input.getAbsolutePath());
System.out.println(input.length());
inputFileTransport.open();
outputFileTransport.open();
System.out.println(inputFileTransport.getBytesRemainingInBuffer());
inputFileTransport.setTailPolicy(tailPolicy.WAIT_FOREVER);
System.out.println("Wait ...");
System.out.println(inputFileTransport.getBuffer());
TFileProcessor fProcessor =
new TFileProcessor(processor, new TJSONProtocol.Factory(), inputFileTransport, outputFileTransport);
try {
fProcessor.processChunk();
} catch (TTransportException e) {
e.printStackTrace();
}
System.out.println("File Thrift service started ...");
} catch (Exception e) {
e.printStackTrace();
}
我遵循了这个线程中的示例: 关于如何在 Thrift (Client/Server) 中使用 TFileTransport 的示例
