多次读取http

服务器，一次性提交数据后，作为客户端的程序，不能一次性读完，而是分两次：
读取结果如下：
第一次：
复制代码
  1. "{\"success\":true,\"errorMsg\":null,\"data\":[{\"uuid\":null,\"whCode\":\"SH-01\",\"whId\":219689,\"orderGroup\":\"B1909270001_1\",\"salesOrderCode\":\"1\",\"skuCode\":\"CC009\",\"skuVolume\":\"0.0\",\"skuEanCode\":\"CC090001001\",\"needSN\":false,\"cellIndex\":\"SO10\",\"qty\":1.0,\"printTypeList\":null,\"remark\":null},{\"uuid\":null,\"whCode\":\"SH-01\",\"whId\":219689,\"orderGroup\":\"B1909270001_1\",\"salesOrderCode\":\"SO201909200001\",\"skuCode\":\"CC002\",\"skuVolume\":\"1.0\",\"skuEanCode\":\"69201705250002\",\"needSN\":false,\"cellIndex\":\"SO1\",\"qty\":3.0,\"printTypeList\":null,\"remark\":null},{\"uuid\":null,\"whCode\":\"SH-01\",\"whId\":219689,\"orderGroup\":\"B1909270001_1\",\"salesOrderCode\":\"SO201909240008\",\"skuCode\":\"CC009\",\"skuVolume\":\"0.0\",\"skuEanCode\":\"CC090001001\",\"needSN\":false,\"cellIndex\":\"SO8\",\"qty\":1.0,\"printTypeList\":null,\"remark\":null},{\"uuid\":null,\"whCode\":\"SH-01\",\"whId\":219689,\"orderGroup\":\"B1909270001_1\",\"salesOrderCode\":\"SO201909240017\",\"skuCode\":\"CC002\",\"skuVolume\":\"1.0\",\"skuEanCode\":\"69201705250002\",\"needSN\":false,\"cellIndex\":\"SO17\",\"qty\":1.0,\"printTypeList\":null,\"remark\":null},{\"uuid\":null,\"whCode\":\"SH-01\",\"whId\":219689,\"orderGroup\":\"B1909270001_1\",\"salesOrderCode\":\"SO201909240020\",\"skuCode\":\"CC002\",\"skuVolume\":\"1.0\",\"skuEanCode\":\"69201705250002\",\"needSN\":false,\"cellIndex\":\"SO20\",\"qty\":1.0,\"printTypeList\":null,\"remark\":null},{\"uuid\":null,\"whCode\":\"SH-01\",\"whId\":219689,\""

第二次：

两次合起来的结果为正确的结果

问题：
为什么就不能一次性读取，我设置了QNetworkReply::setReadBufferSize(qint64 size)，也没什么用，有没有什么好的办法可以解决。

应该是要监听finished槽函数，不过qt的那一套我不用
建议你用libcurl，这个最专业，专业的事情交给专业的库来做
qt就只用来弄来个界面壳

好人啊，改成finished果然就可以了。
