我正在尝试将一些数据发布到我的服务器（字符串）。我得到一个缺少的参数错误，但我不知道为什么。我注销了NameValuePair的内容，数据似乎就在那里。
我正在通过模拟器运行它。如果params在那里，有什么想法服务器会重新出现这样的错误吗？

答案 0 :(得分：1)
你得到了
E/WebService(500): responseBody = Missing parameter: UserID.
当你尝试
时 Log.e(TAG, "responseBody = " + responseBody);
DocObjModParser dp = new DocObjModParser(context);
serviceStatus = dp.getPostTransactionResponseCode(responseBody); // <== this fails!
毫不奇怪，DocObjModParser无法解析响应字符串“Missing parameter：UserID。”
响应建议将用户ID添加到http查询。
我建议打印httppost并尝试首先通过浏览器执行它（它可能会立即给你一个提示），然后，通过curl，可以使用命令行实用程序在Linux或Cygwin中（不确定普通的Windows）。
另一个建议是将打印的httppost与有效的请求进行比较。谁知道，脚本可能对参数的顺序很敏感，或者某些字符串包含应该进行URL编码的字符。
UPD：问题可能在于标题
