Android E/截击﹕；[194]BasicNetwork.performRequest:url的意外响应代码307

我正试图在我的android应用程序中通过截取将json obj通过POST发送到api并捕获json响应，但我一直收到以下错误： E/截击﹕ [194]BasicNetwork.performRequest:的意外响应代码307

有一段代码发出请求：

有人能告诉我为什么我一直收到这个错误吗？

响应代码307表示临时重定向

请检查服务器端是否存在此问题

更多解释：

服务器将此响应发送给指示客户端获取请求的客户端 使用与先前请求相同的方法将资源复制到另一个URI。这 与302 Found HTTP响应代码具有相同的语义 例外情况是，用户代理不能更改所使用的HTTP方法：如果 在第一个请求中使用了一个POST，在 第二个请求

---

有关更多信息，请参见：

您可以通过在url末尾添加

/

来避免307回复代码，即

http://phoneapi.adro.co/Services/AdService.svc/GetAd/

然后使用下面的示例代码（我使用了

jsonBody

），您应该更多地检查您的web服务，因为此代码将得到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;
    }
};

JsonObjectRequest request=newjsonobjectrequest（request.Method.POST、url、jsonBody、newresponse.Listener（））{
@凌驾
公共void onResponse（JSONObject响应）{
Log.i（“onResponse”，response.toString（））；
}
}，new Response.ErrorListener（）{
@凌驾
公共无效onErrorResponse（截击错误）{
Log.i（“onErrorResponse”，error.toString（））；
}
}){
@凌驾
受保护的截击错误解析NetworkError（截击错误截击错误）{
if（volleyError.networkResponse！=null&&volleyError.networkResponse.data！=null）{
截击错误=新截击错误（新字符串（截击错误.networkResponse.data））；
截击错误=错误；
}
回击失误；
}
};

调试时（将断点设置为

VolleyError error=new-VolleyError（新字符串（VolleyError.networkResponse.data））；

），您将获得以下信息：

服务器在处理请求时遇到错误。异常消息为“对象引用未设置为对象的实例”。有关详细信息，请参阅服务器日志。异常堆栈跟踪为：

在AdroMobileApi.Services.AdService.GetAd（AdRequest请求）
在SyncInvokeGetAd（对象，对象[]，对象[]）
位于System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke（对象实例、对象[]输入、对象[]输出）
位于System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin（MessageRpc&；rpc）
位于System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5（MessageRpc&；rpc）
位于System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage11（MessageRpc&；rpc）
位于System.ServiceModel.Dispatcher.MessageRpc.Process（布尔isOperationContextSet）

啊哈，你能告诉我如何在服务器端解决这个问题吗？首先，你的答案太棒了！第二，你的意思是我应该检查我的PHP？所以这是一个服务器端问题？我建议您多检查它以解决400而不是307。您可以使用php搜索未设置为对象实例的

对象引用，也许某个变量为空。但是，在解决307问题后，如果您的android代码与web服务（php）一起工作，当然您不必查看php代码
