【报Bug】uni.request无法有效实现发出的Http post消息头content-type为application/x-www-form-urlencoded

示例代码：

export const HttpRequest = (url, data, method) => {

let header = ""  

if (method == "POST") {  
    //header = "'content-type': 'application/json;charset:utf-8'"  
    header = "'content-type': 'application/x-www-form-urlencoded'"  
} else {  
    header = ""  
}  

return new Promise((resolve, reject) => {  

    let urls = BASE_URL + url  
    // console.log("地址", urls)  
    uni.request({  
        url:urls.replace (/\s*/g,"") ,  
        method: method || 'GET',  
        data: data || {},        //对于'content-type': 'application/json;charset:utf-8'  
        //data:data,             //对于'content-type': 'application/x-www-form-urlencoded'  
        header: {  
            header,  
        },  
        success: (res) => {  
            resolve(res)  
        },  
        //请求失败  
        fail: (err) => {  
            reject(err)  
        }  
    })  
})  

}

调用代码：
var code=e.detail.code;
var data={code:code};
//var data="code="+code;
HttpRequest("/wechat/weixin/getPhoneNumber/hznev",data,"POST");

操作步骤：

var code="dfdfdfdfdsdfewrf";
var data={code:code};
//var data="code="+code;
HttpRequest("/wechat/weixin/getPhoneNumber/hznev",data,"POST");

预期结果：

抓包确认发出的post消息头中content-type值为application/x-www-form-urlencoded

实际结果：

抓包确认发出的post消息头中content-type值总是不变为application/json
