E/Volley：[194] BasicNetwork.performRequest：url 出现意外响应代码 307

我试图在我的 Android 应用程序中通过 POST 将 json obj 通过 volley 发送到 api 并捕获 json 响应，但我不断收到此错误： E/Volley：[194] BasicNetwork.performRequest：意外的响应代码 307http://phoneapi.adro.co/Services/AdService.svc/GetAd http://phoneapi.adro.co/Services/AdService.svc/GetAd .

有一段代码发出请求：

谁能告诉我为什么我不断收到此错误？

你可以避免307通过添加响应代码/在你的网址的末尾，即http://phoneapi.adro.co/Services/AdService.svc/GetAd/

然后使用以下示例代码（我用了你的jsonBody），您应该更多地检查您的网络服务，因为此代码将得到400而是响应代码

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（设置断点VolleyError error = new VolleyError(new String(volleyError.networkResponse.data));），你会得到一些信息，例如

The server encountered an error processing the request. The exception message is 'Object reference not set to an instance of an object.'. See server logs for more details.
