Taro: Taro.request()当有header参数时GET请求变成OPTIONS

Created on 17 May 2019 · 3Comments · Source: NervJS/taro

问题描述
当Taro.request()中有header参数时，method参数为'GET'时不起作用，请求被固定为OPTIONS。

复现步骤

带header参数时

Taro.request({
            url: serverUrl + '/api/base/dict/common/policy_regulation',
            method: 'GET',
            header: {
                'content-type': 'application/json'
            }
        }).then(res => console.log(res.data))

Request URL: http://127.0.0.1:8080/api/base/dict/common/policy_regulation
Request Method: OPTIONS
Status Code: 200 
Remote Address: 127.0.0.1:8080
Referrer Policy: no-referrer-when-downgrade

不带header参数时

Taro.request({
            url: serverUrl + '/api/base/dict/common/policy_regulation',
            method: 'GET'
        }).then(res => console.log(res.data))

Request URL: http://127.0.0.1:8080/api/base/dict/common/policy_regulation
Request Method: GET
Status Code: 200 
Remote Address: 127.0.0.1:8080
Referrer Policy: no-referrer-when-downgrade

期望行为
request method不应该受header参数的影响
