小编dro*_*823的帖子

我收到以下错误:

<error_code>104</error_code>
<error_msg>Incorrect signature</error_msg>

我应该将contentType类型设置为什么？我应该设置为:

String contentType = "application/x-www-form-urlencoded";

要么

String contentType = "multipart/form-data; boundary=" + kStringBoundary; 

这就是我写流的方式:

HttpURLConnection conn = null;
OutputStream out = null;
InputStream in = null;
try {
    conn = (HttpURLConnection) _loadingURL.openConnection();
    conn.setDoOutput(true);
    conn.setDoInput(true);
    if (method != null) {
        conn.setRequestMethod(method);
        if ("POST".equals(method)) {
            //"application/x-www-form-urlencoded";
            String contentType = "multipart/form-data; boundary=" + kStringBoundary;
            //String contentType = "application/x-www-form-urlencoded";
            conn.setRequestProperty("Content-Type", contentType);
        }

        // Cookies are used in FBPermissionDialog and FBFeedDialog to
        // retrieve logged user
       conn.connect();
       out = conn.getOutputStream();
       if …
