您好我已用c ++编写代码以使用cURL发布请求。此外，我还编写了一个代码，在groovy中接收此请求。在测试代码时，似乎curl重新发布请求。但我有点不确定，因为它没有反映在我的卷曲痕迹中。另一方面，我的套接字流反映了这一点。我猜不出问题出在哪里。
期望：
服务器端： 如果服务器收到某个特定请求，它会发送一些响应消息，如果不是，它只会发送一些整数（为了测试它现在是整数）。
客户方： 它会偶尔发送请求并获得响应，如果没有要求它只会听取接收消息（例如那些整数）
C ++ Curl Call：
if(curl){
curl_easy_setopt(curl, CURLOPT_DEBUGFUNCTION, my_trace);
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
curl_easy_setopt(curl,CURLOPT_FOLLOWLOCATION, 1);
string Mydata;
char errbuf[CURL_ERROR_SIZE];
chunk.memory = (char*)malloc(1); /* will be grown as needed by the realloc above */
chunk.size = 0; /* no data at this point */
FILE * rfp = fopen("/Users/Uma/request.xml", "r");
if(rfp != NULL){
cout<<"File is opened "<<endl;
}else{
cout<<"File is close"<<endl;
}
curl_easy_setopt(curl, CURLOPT_URL, myUrl);
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, header);
const char* req= "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:blz=\"http://thomas-bayer.com/blz/\"> <soapenv:Header/> <soapenv:Body> <blz:getBank> <blz:blz>50070010</blz:blz> </blz:getBank> </soapenv:Body> </soapenv:Envelope> \n";
curl_easy_setopt(curl,CURLOPT_HTTPPOST, 1L);
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, req);
cout<<"requested posted "<<endl;
curl_easy_setopt(curl, CURLOPT_READFUNCTION, reader);
curl_easy_setopt(curl, CURLOPT_READDATA, rfp);
errbuf[0] = 0;
/* send all data to this function */
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteMemoryCallback);
curl_easy_setopt(curl,CURLOPT_WRITEDATA,(void *)&chunk);
curlCode = curl_easy_perform(curl);
// always cleanup
if(curlCode != CURLE_OK | curlCode != 0) {
std::cout<<" traced data "<<traceData<<std::endl;
size_t len = strlen(errbuf);
fprintf(stderr, "\nlibcurl: (%d) ", curlCode);
if(len)
fprintf(stderr, "%s%s", errbuf,
((errbuf[len - 1] != '\n') ? "\n" : ""));
else
fprintf(stderr, "%s\n", curl_easy_strerror(curlCode));
} else {
std::cout<<"CURl Code "<<curlCode<<std::endl;
/*
* Now, our chunk.memory points to a memory block that is chunk.size
* bytes big and contains the remote file.
*/
std::cout<<"CURL code on error --"<<curlCode<<std::endl;
printf("%lu bytes retrieved\n", (long)chunk.size);
//cout<<"My Response ---"<<response<<endl;
cout<<"My Chunck -- "<<chunk.memory<<endl;
}
curl_easy_cleanup(curl);

def sendMessage(msg, writer) {
println("Sending: >" + msg + "<")

请注意，在我杀死客户端后还会添加一条请求消息。它刚好位于推送消息开始的正上方。
