C++のカールを使用してWebサービスからの応答を受け取ることができます

Question

curlとC++を使用してWebサービスからの応答を取得しようとしています。私は端末からウェブサービスを呼び出そうとしました。それはうまく動作し、私は応答を受け取ることができます。

しかし、私はC++でこれを再現することはできません。コードから

Request.xml 
<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> 


void dataFromWebService :: connectWithWebservice(){  

struct curl_slist *header = NULL; 
header = curl_slist_append (header, "Content-Type:text/xml"); 
header = curl_slist_append (header, "charset=UTF-8"); 
header = curl_slist_append (header, "SOAPAction:urn:getBank"); 

curl = curl_easy_init();  

if(curl == NULL){ 

    cout<<"CURL is NULL"; 
} 

const char *myUrl = "http://www.thomas-bayer.com/axis2/services/BLZService"; 

//const char *myUrl = "http://11.22.33.231:9080/VehicleInfoQueryService.asm"; 
if(curl){ 

    string Mydata; 

    char errbuf[CURL_ERROR_SIZE]; 
    struct MemoryStruct chunk; 

    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("request.xml", "r"); 

    curl_easy_setopt(curl, CURLOPT_URL, myUrl); 

    //curl_easy_setopt(curl, CURLOPT_HTTPGET, 1L); 
    curl_easy_setopt(curl, CURLOPT_READDATA, rfp); 
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, header); 

    curl_easy_setopt(curl, CURLOPT_HTTPGET, 1L); 
    curl_easy_setopt(curl,CURLOPT_FOLLOWLOCATION, 1); 
    curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L); 

    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteMemoryCallback); 

    char *response = NULL; 
    /* passing the pointer to the response as the callback parameter */ 
    curl_easy_setopt(curl, CURLOPT_WRITEDATA, (void *)&chunk); 



    errbuf[0] = 0; 
    cout<< "The result from webservice "<<endl; 

    /* Perform the request, res will get the return code */ 

    curlCode = curl_easy_perform(curl); 

    /* send all data to this function */ 

    curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteMemoryCallback); 

    curl_easy_setopt(curl,CURLOPT_WRITEDATA,(void *)&chunk); 


    cout <<"curl code-- "<<curlCode<<endl; 


    // always cleanup 
    if(curlCode != CURLE_OK | curlCode != 0) { 
     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 { 
     /* 
     * Now, our chunk.memory points to a memory block that is chunk.size 
     * bytes big and contains the remote file. 
     */ 

     printf("%lu bytes retrieved\n", (long)chunk.size); 

     cout<<"My Chunck -- "<<chunk.memory<<endl; 
    } 
    curl_easy_cleanup(curl); 

} 

}

Answer 1

私自身の質問に答えるのは少し恥ずかしいです。

リクエストのファイルポインタではなく、リクエストchar *でHttp Postを使用する必要があります。

次のように動作します。

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>"; 

curl_easy_setopt(curl,CURLOPT_HTTPPOST, 1L); 
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, req); 

「標準SOAPサービスは唯一のHTTP POSTを使用している彼らは、クエリ文字列に含めることができない複雑なSOAPリクエスト（XML）を必要とするため。」ので、これは

理由SOAP only works with POST method even though it is transported by HTTPかもしれないが、私にはありません。。。this example from curl作品
