android - E/Volley:[194] BasicNetwork.performRequest : Unexpected response code 307 for url

Question

我正在尝试通过 POST 将 json obj 通过 volley 在我的 android 应用程序中发送到 api 并捕获 json 响应，但我不断收到此错误: E/Volley:[194] BasicNetwork.performRequest:http://phoneapi.adro.co/Services/AdService.svc/GetAd 的意外响应代码 307| .

有一段代码发出请求:

谁能告诉我为什么我总是收到这个错误？

Answer 1

您可以通过添加 / 来避免 307 响应代码在您的网址末尾，即 http://phoneapi.adro.co/Services/AdService.svc/GetAd/

然后使用以下示例代码(我使用了你的 jsonBody )，你应该更多地检查你的网络服务，因为这段代码将得到 400 响应代码

JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, jsonBody, new Response.Listener<JSONObject>() {
    @Override
    public void onResponse(JSONObject response) {
        Log.i("onResponse", response.toString());
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        Log.i("onErrorResponse", error.toString());
    }
}){
    @Override
    protected VolleyError parseNetworkError(VolleyError volleyError) {
        if(volleyError.networkResponse != null && volleyError.networkResponse.data != null){
            VolleyError error = new VolleyError(new String(volleyError.networkResponse.data));
            volleyError = error;
        }

        return volleyError;
    }
};

调试时(在VolleyError error = new VolleyError(new String(volleyError.networkResponse.data));设置断点)，会得到一些信息如
