我正在尝试使用 Java (HTTP Post) 上传文件:

HttpURLConnection conn = (HttpURLConnection) new URL(_uploadTarget).openConnection();
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
conn.setDoOutput(true);
long fileLength = fileContentLength + tail.length();
String stringData = "--" + boundary + "\r\nContent-Disposition: form-data; name=\"metadata\"\r\n\r\n" + metadata + "\r\n" + "--" + boundary + "\r\nContent-Disposition: form-data; name=\"uploadfile\"; filename=\"" + fileName + "\"\r\nContent-Type: application/octet-stream; charset=UTF-8\r\nContent-Transfer-Encoding: binary\r\n" + "Content-length: " + fileLength + "\r\n\r\n";

long requestLength = stringData.length() + fileLength;
conn.setRequestProperty("Content-length", "" + requestLength);
conn.setFixedLengthStreamingMode((int) requestLength);
conn.connect();
DataOutputStream out = new DataOutputStream(conn.getOutputStream());

out.writeBytes(stringData);
out.flush();

int progress = 0;
int bytesRead = 0;
byte b[] = new byte[1024];
BufferedInputStream bufin = new BufferedInputStream(
        new FileInputStream(_file));
while ((bytesRead = bufin.read(b)) != -1) {
    out.write(b, 0, bytesRead);
    out.flush();
    progress += bytesRead;
}

out.writeBytes(tail);
out.flush();
out.close();

BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
StringBuilder sb = new StringBuilder();

while ((line = rd.readLine()) != null) {
    sb.append(line);
}

public void ProcessRequest(HttpContext context) {
var uploadedFile = context.Request.Files[0]; // often throws exception with message: "Thread was being aborted."
}

这段代码有时有效。希望有人能帮忙。

有帮助吗?

解决方案

看到我不知道你遇到了什么错误/异常,因为你正在使用上传文件 HttpURLConnection, ,那么我建议阅读:

其他提示

尽管您的代码示例中缺少一些关键信息,但我认为您的 Java 部分很好,因为它“有时可以工作”并且异常是特定于 C# 的。

我不做 C#,但是 谷歌 通过以下链接揭示您的 Stackoverflow 问题: http://www.debugging.com/bug/14721. 。以下是相关性的摘录:

通过将请求执行超时计时器设置为比 2 分钟稍高的值来解决这个问题:)

如果请求处理确实需要那么长时间,您的解决方案可能是将超时设置得更高。
