教你如何在mql4中进行数据哈希运算

Alexandr Bryzgalov 2013.09.28 13:01 #21

Reshetov:

问题是，间接费用可以计算，但你无法看到其背后的利润。

我已经盈利了，而且不差钱，这都是加密的问题。

Alexandr Bryzgalov 2013.09.28 13:03 #22

TheXpert:

首先，它不是SHA256，是HMAC SHA512。

它是在BTC-e上

Yury Reshetov 2013.09.28 13:09 #23

sanyooooook:
我已经在获利了，而且不差钱，这只是一个加密的问题。

这条信息之后，再想加密获利就太晚了：敲诈者已经知道了，很快就会停下来。而且他们没花多长时间就找到了：郊区那座没有屋顶的房子就是sanyooooook 加密利润的地方。

明白了。顺便说一句，你不应该害怕。顺便说一下，对于winapi，你必须先编写工作代码，然后将其翻译成mql。而用mql写的东西，是一个独立的程序...意思是什么？

如果你不想学习Sharp，你就必须学习Python。如果你想要钱，你将不得不学习。

你不想学Sharp，就学Python吧。你想要面团，你就得学习。

妈的，看看这个。

1.交换api，以json格式发送一个帖子请求（json不难）。

2.在这个查询中，部分数据是散列的，这里我有一个问题，但这不是一个问题。我想明白了（暂时我通过输入数据的愚蠢散列推迟了代码的实施）。

3.这个东西不会发送任何东西，也许我做错了帖子？

一旦你可以发送请求，你就可以准备好一套交易功能了。

葵花籽，但它不会返回任何东西给我((!

字符串在请求时是正确的，但我一定是使用了错误的POST函数。

所以我说用任何正常的语言来写，并找出问题所在，然后把它翻译成MQL。

实际上，在GET和POST请求中，所有的东西都是以：id=value的形式传递的，也就是说，参数名称和值都有一个等号。另外，所有非拉丁字母和数字的字符都用%（字符代码）进行编码。

也就是说，如果我们假设数组params存储了所传递参数的标识符，那么变量s肯定也应该是一个相同大小的数组，以传递与参数对应的值？
