http客户端发送消息

[dingyaoyang]

客户端发送data

WFFacilities::WaitGroup wait_group(1);
WFHttpTask *task = WFTaskFactory::create_http_task(uuu, REDIRECT_MAX, RETRY_MAX,
[&res,&state,&wait_group](WFHttpTask *task)
{
	state = task->get_state();
	auto *resp = task->get_resp();

	if (state == WFT_STATE_SUCCESS)
	{
              const void *body = nullptr;
              size_t size = 0;
		resp->get_parsed_body(&body, &size);
              res = std::string((char *)body, size);
	}
	
	wait_group.done();
}
);
  
task->get_req()->append_output_body(data);
task->start();

wait_group.wait();

服务拿消息：

WFHttpServer server([](WFHttpTask* task){
      printf("%d\n",task->get_state());
      printf("%d\n",task->get_error());
      const void * body;
      size_t size;
      task->get_resp()->get_parsed_body(&body, &size);
      printf("Get%d: %s\n", size, body);
  });
  server.start(9990);
  while(1){}

返回：

为什么拿不到消息

[xiehan]

你能把client的代码贴完整吗？

[xiehan]

是不是你二进制数据的原因？printf打印的是字符串，不能打印二进制吧。我wget里的示例，是用fwrite输出的。

bool BSConnect::uploadLog(BSLDATA data)
{
    json jstr;
    jstr["businessType"] = data.businessType;
    jstr["businessName"] = UrlEncode(data.businessName);
    jstr["requestData"] = UrlEncode(data.requestData);
    jstr["opResult"] = data.opResult;
    jstr["opReason"] = UrlEncode(data.opReason);
    jstr["useTime"] = data.useTime;
    jstr["requestTime"] = data.requestTime;

    std::string res = CreateTask(uploadUri, jstr.dump());

    // 结果判断
    if(res.empty())
    {
        return false;
    }

    // 解析json
    json jres;
    try
    {
        jres = json::parse(res);
    }
    catch(const json::exception& e)
    {
        return false;
    }

    if(jres["retCode"] == 1)
    {
        return true;
    }
    else
    {
        return false;
    }
}

std::string BSConnect::CreateTask(std::string uri, std::string data)
{
    std::string uuu = url+uri;
    if(uri == uploadUri)
    {
        uuu = "http://127.0.0.1:9990";
    }
    std::string res;
    int state;

	WFFacilities::WaitGroup wait_group(1);
	WFHttpTask *task = WFTaskFactory::create_http_task(uuu, REDIRECT_MAX, RETRY_MAX,
		[&res,&state,&wait_group](WFHttpTask *task)
		{
			state = task->get_state();
			auto *resp = task->get_resp();

			if (state == WFT_STATE_SUCCESS)
			{
                const void *body = nullptr;
                size_t size = 0;
				resp->get_parsed_body(&body, &size);
                res = std::string((char *)body, size);
                size = 123;
			}
			
			wait_group.done();
		}
	);
    
	task->get_req()->append_output_body(data);
	task->start();

	wait_group.wait();
	return res;
}

传的数据"{"businessName":"SDF_OpenSession","businessType":1,"opReason":"test","opResult":1,"requestData":"%7B%22hDeviceHadnle%22%3A1%7D","requestTime":"2024-04-16 19:15:10","useTime":"35"}"

数据长度也没拿到

[xiehan]

server能运行到process，但get_parsed_body()却拿不到你的请求和数据长度？size得到是的多少？

[xiehan]

应该是task->get_req()->get_parsed_body() .... 这是request啊，不是response。

[dingyaoyang]

还有一个问题，我用workflow传数据，java后台(也是http协议，没用workflw)能拿到吗？

[xiehan]

肯定可以啊，要不然协议有什么用。

[dingyaoyang]

好的，谢谢
