Question

我收到以下错误

InvalidPolicyDocument的内容表格不符合政策中规定的条件 document.Policy文档解析错误：Lexical 错误：输入不匹配：＆lt; s＆gt;

我的异步任务调用HTTPURLConnection如下。 multipartv1类来自here。

在AsyncTask doinbackground内部

{multipartv1.addFormField("key", filename_insert_value);
multipartv1.addFormField("bucket", “myapplication”);
multipartv1.addFormField("Content-Type", "image/jpeg");
multipartv1.addFormField("GoogleAccessId", “myapplication@appspot.gserviceaccount.com");
multipartv1.addFormField("acl", "bucket-owner-read");
multipartv1.addFormField("success_action_redirect", "https://myapplication.appspot.com/getpolicydocumentsuccess");
multipartv1.addFormField("success_action_status", "201");
multipartv1.addFormField("x-goog-meta-programname", this.current_program_name);
multipartv1.addFormField("x-goog-meta-membername", this.member_element_id);
multipartv1.addFormField("x-goog-meta-tag1", tag1);
multipartv1.addFormField("x-goog-meta-tag2", tag2);
multipartv1.addFormField("x-goog-meta-tag3", tag3);
multipartv1.addFormField("x-goog-meta-tag4", tag4);
multipartv1.addFormField("x-goog-meta-tag5", tag5);
multipartv1.addFormField("policy", this.policy);
multipartv1.addFormField("signature", this.signature);

multipartv1.addFilePart("file", new File(this.file_absolute_path));

List<String> response_multipart = multipartv1.finish();
Log.e(Tag, "SERVER REPLIED:");
for (String line : response_multipart) {
Log.e(Tag, "Upload Files Response:::" + line);
}

＆＃34;政策＆＃34;是使用Google Cloud Endpoint API从我的后端（Google App Engine）生成的。这是由列出的here列出的Google云端存储XML API支持的政策文档。＆＃34;政策＆＃34;通过Web应用程序访问时工作正常。

＆＃34;政策＆＃34;看起来像这样 -

我担心的是当我为＆＃34; policy＆＃34;添加参数时在我的HttpURLConnection中，有些东西搞砸了。添加＆＃34;策略的代码＆＃34;参数是这个 -

 public void addFormField(String name, String value) {
            writer.append("--" + boundary).append(LINE_FEED);
            writer.append("Content-Disposition: form-data; name=\"" + name + "\"")
                    .append(LINE_FEED);
            writer.append("Content-Type: text/plain; charset=" + charset).append(
                    LINE_FEED);
            writer.append(LINE_FEED);
            writer.append(value).append(LINE_FEED);
            writer.flush();
        }

HTTP Post调用在这里 -

public List<String> finish() throws IOException {
        List<String> response = new ArrayList<String>();
        writer.append(LINE_FEED).flush();
        writer.append("--" + boundary + "--").append(LINE_FEED);
        writer.close();

        // checks server's status code first
        int status = httpConn.getResponseCode();
        if (status == HttpURLConnection.HTTP_OK) {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    httpConn.getInputStream()));
            String line = null;
            while ((line = reader.readLine()) != null) {
                response.add(line);
            }
            reader.close();
            httpConn.disconnect();
        } else {
            throw new IOException("Server returned non-OK status: " + status);
        }
        return response;
    }

边界字符串是

   String boundary = "===" + System.currentTimeMillis() + "===";

通过Google CloudEndpoint API访问的Google云端存储XML API政策文档。词法错误：无与伦比的输入
