C ++ std :: string如何格式化带有多个双引号的String文字？

Question

I have a std::string literal with double quotes inside double quotes, inside double quotes. What format do I need to use to make it work? Here is an example:

std:string http_command = "wget --post-data="user=bla password=bla query=select * from bla bla where username="" and name=bla\" http:://example.com"

The following part is failing username=""

Thanks guys.

Update: Fixed my sample, I had one extra double quote there.

Answer 1

std::string http_command = "wget --post-data=\"user=bla password=bla query=\"select * from bla bla where username=\"\" and name=bla\" http:://example.com"

转义除第一个和最后一个（界定您的字符串的那些）之外的所有引号。

Answer 2

std:string http_command = "wget --post-data=\"user=bla password=bla query=\\\"select * from bla bla where username=\\\\\\"\\\\\\" and name=bla\\\" \" http:://example.com"

A bit of a guess, but I think that you have to escape the internal backslahes. Note that I think you were missing a quote at the end of the post data.
