E / Volley：[194] BasicNetwork.performRequest：url
我正在尝试通过POST将json obj发送到api，通过我的Android应用程序中的截击并捕获json响应，但我一直收到此错误： E / Volley：[194] BasicNetwork.performRequest：http://phoneapi.adro.co/Services/AdService.svc/GetAd的意外响应代码307。

谁能告诉我为什么我会一直收到这个错误？
2 个答案:
答案 0 :(得分：5)
您可以在网址末尾添加/来避免 307 响应代码，即http://phoneapi.adro.co/Services/AdService.svc/GetAd/
然后使用以下示例代码（我使用了您的jsonBody），您应该检查您的网络服务，因为此代码将获得 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));处设置断点），您将获得一些信息，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. The exception stack trace is: </p>

响应代码307 表示临时重定向。
请检查您的服务器端是否存在此问题。
更多说明：
服务器将此响应发送给指示客户端以获取请求 资源到另一个URI，使用与先前请求相同的方法。这个 具有与302 Found HTTP响应代码相同的语义 用户代理不得更改所使用的HTTP方法的异常：if 在第一个请求中使用了POST，必须在中使用POST 第二次请求。
