this.curl发起请求，无法带上自定义header

[steelli]

Your detail info about the Bug:

如下是一个调用OpenAI api的controller，请求OpenAI API接口的时候，自定义header带不上。
const Controller = require('egg').Controller;

class OpenAIController extends Controller {
async completions() {
const param = this.ctx.request.body;
const apiUrl = ${this.config.openai.baseUrl}/completions;
try {
const result = await this.ctx.curl(apiUrl, {
method: 'POST',
contentType: 'json',
headers: {
Authorization: Bearer ${this.config.openai.apiKey}},
},
data: param,
streaming: param.stream,
dataType: 'json',
});
this.ctx.status = result.status;
this.ctx.set(result.header);
this.ctx.body = result.data;
} catch (error) {
this.ctx.status = 200;
this.ctx.body = { error: 'error' };
this.ctx.logger.info('OpenAI API call failed:', error);
}
}
}

module.exports = OpenAIController;

如下是抓包的结果：

从抓包的请求中可以看到，并没有自定义headers Authorization 这个请求头，这个是不符合预期的。

注意：上述示例中的代码要运行，需要将config/config.default.js中的apikey字段设置成一个有效的apikey
