Question

每当我尝试在我的app中使用api时获得此响应。这是我在api hit中获得的响应。我在头文件中放置的内容类型是.application / json; charset = utf-8但在respnose中它们是错误并显示ascii字符。需要帮助解决它。

> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML
> 4.01//EN""http://www.w3.org/TR/html4/strict.dtd"> <HTML><HEAD><TITLE>Bad     Request</TITLE> <META HTTP-EQUIV="Content-Type"
> Content="text/html; charset=us-ascii"></HEAD> <BODY><h2>Bad Request -
> Invalid Header</h2> <hr><p>HTTP Error 400. The request has an invalid
> header name.</p> </BODY></HTML>

这是我放置标题的类..

public class CustomJSONStringRequest extends StringRequest {
public CustomJSONStringRequest(int method, String url, Response.Listener<String> listener,
                               Response.ErrorListener errorListener) {
    super(method, url, listener, errorListener);
}
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
    HashMap<String, String> headers = new HashMap<String, String>();
    headers.put("Cache-Control","no-cache");
    headers.put("Content-Type", "application/json; charset=utf-8");
    headers.put("Authorization", ".....");
    headers.put("X-API-KEY", "......");
    return headers;
} }

Answer 1

尝试使用“接受”而不是“内容类型”
