截击身体400错误

Question

我想向服务器发送一篇帖子，帖子的正文是真是假。我有这个代码，我使用截击库

ShoozyHeader（）将内容类型设置为text/plain，并将Accept设置为text/plain以及身份验证所需的其他标头。

如果我尝试http://requestmaker.com/，服务器正确响应，但我运行此代码，服务器响应：

错误的请求-无效的头HTTP错误400。请求的标头名称无效。

如果删除getBody（），服务器响应良好。

    final String url = POSTS_URI + idPost + "/likes";

    StringRequest strReq = new StringRequest(Request.Method.POST,
            url, new Response.Listener<String>() {

        @Override
        public void onResponse(String response) {
            Log.d(TAG, response);
        }
    }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            VolleyLog.d(TAG, "Error: " + error.getMessage());
            Toast.makeText(act, "Network error", Toast.LENGTH_SHORT).show();
        }
    }
    ) {
        @Override
        public byte[] getBody() throws AuthFailureError {
            return "true".getBytes();
        }
    };

Answer 1

您是否在扩展请求的类中重写了GetHeader？

以下是如何：

@Override
public Map<String, String> getHeaders() throws AuthFailureError {
    return headers != null ? headers : super.getHeaders();
}

下面是设置Base64（用户名、密码）头的示例：

@Override
    private HashMap<String, String> getHeaders() {
        HashMap<String, String> headers = new HashMap<>();
        headers.put("Authorization", getAuthentication("usernameExample", "passwordExample"));
        headers.put("Content-Type", "application/json; charset=utf-8");
        Log.d(TAG + "");
        return headers;
    }

private String getAuthentication(String username, String password) {
        String credentials = String.format("%s:%s", username, password);
        String auth = "Basic " + Base64.encodeToString(credentials.getBytes(), Base64.DEFAULT);
        return auth;
    }

试试这个，它对我很管用：

JSONObject params = new JSONObject();

try {
    params.put("likes", "true");

} catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
//

JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
        url, params,
        new Response.Listener<JSONObject>() {

            @Override
            public void onResponse(JSONObject response) {
                Log.d(TAG, response.toString());
            }
        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.d(TAG, "Error: " + error.getMessage());
            }
        }) {

    /**
     * Passing some request headers
     * */
    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        HashMap<String, String> headers = new HashMap<String, String>();
        headers.put("Content-Type", "application/json; charset=utf-8");
        return headers;
    }

};
jsonObjReq.setRetryPolicy(new DefaultRetryPolicy(60000,
        DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
        DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

// Adding request to request queue
getRequestQueue(jsonObjReq);
