问题

我现在有一个问题，尝试从`system()`函数内部发送一个CURL请求到OpenAI API。我无法使用额外的库，比如libcurl，所以我尝试使用控制台请求来实现这个目标。

这是我的代码：

```c++
int main() {
    std::string command = "curl -X POST -H \"Content-Type: application/json\" -H \"Authorization: Bearer API_KEY\" -d \"{\"prompt\": \"Hello, World!\", \"max_tokens\": 5}\" https://api.openai.com/v1/engines/davinci-codex/completions\"";
    int result = system(command.c_str());
    return 0;
}

但我得到这个错误：

curl: (3) unmatched close brace/bracket in URL position 22:
    World!, max_tokens: 5}

我应该如何正确格式化我的命令字符串？

我尝试使用CURL请求的-g属性，但这也不起作用。

即使我成功运行代码，我还会收到来自OpenAI的另一个错误：

{
    "error": {
        "message": "We could not parse the JSON body of your request. (HINT: This likely means you aren’t using your HTTP library correctly. The OpenAI API expects a JSON payload, but what was sent was not valid JSON. If you have trouble figuring out how to fix this, please send an email to support@openai.com and include any relevant code you’d like help with.)",
        "type": "invalid_request_error",
        "param": null,
        "code": null
    }
}

I have a bit of a problem right now with sending a CURL request for OpenAI API from inside the `system()` function. I can&#39;t use additional libraries for this goal such as libcurl, so I am trying to do this with a console request.

This is my code:

```c++
int main() {     
    std::string command = &quot;curl -X POST -H \&quot;Content-Type: application/json\&quot; -H \&quot;Authorization: Bearer API_KEY\&quot; -d \&quot;{\&quot;prompt\&quot;: \&quot;Hello, World!\&quot;, \&quot;max_tokens\&quot;: 5}\&quot; https://api.openai.com/v1/engines/davinci-codex/completions&quot;;     
    int result = system(command.c_str());     
    return 0; 
}

But I get this error:

curl: (3) unmatched close brace/bracket in URL position 22:
    World!, max_tokens: 5}

How should I properly format my command string?

I tried using the -g property for the CURL request, but this doesn't work, either.

Even if I somehow succeed to run the code, I get another error but from OpenAI:

{
    "error": {
        "message": "We could not parse the JSON body of your request. (HINT: This likely means you aren’t using your HTTP library correctly. The OpenAI API expects a JSON payload, but what was sent was not valid JSON. If you have trouble figuring out how to fix this, please send an email to support@openai.com and include any relevant code you’d like help with.)",
        "type": "invalid_request_error",
        "param": null,
        "code": null
    }
}

不要在会被Shell解释的字符串周围使用"。像[tag:bash]这样的Shell会将!在Hello, World!中解释为事件。相反，请在发送给Shell的字符串周围使用'。

此外，使用原始字符串文字（列表中的第6点），无需转义特殊字符。

示例：

#include <cstdlib>
#include <iostream>

int main() {
    std::string command =
        R"aw(curl -X POST -H 'Content-Type: application/json' -H 'Authorization: Bearer API_KEY' -d '{"prompt": "Hello, World!", "max_tokens": 5}' https://api.openai.com/v1/engines/davinci-codex/completions)aw";
    std::system(command.c_str());
}

#include <cstdlib>
#include <iostream>

int main() {
    std::string command =
        R"aw(curl -X POST -H 'Content-Type: application/json' -H 'Authorization: Bearer API_KEY' -d '{"prompt": "Hello, World!", "max_tokens": 5}' https://api.openai.com/v1/engines/davinci-codex/completions)aw";
    std::system(command.c_str());
}
