http代理服务器（十四）jira bitbucket confluence 修复

十三后 有三个问题：

1 jira上传文件不行

2 git 删除分支不行

3 confluence edit 后save不行

 

解决：

1 一开始猜测拖入文件上传这个功能与前端有关系，后来发现点击浏览上传文件也有相同错误

那么问题就可以猜测为 Content-type 或者http request body 没传或传错之类的问题

查看代码，发现往后端发送body时，用的竟然是StringEntity，改为同包下ByteArrayEntity后，点击上传，拖入上传和粘贴板上传都修复

 

2 confluence edit 后save不行

 

2.1 最初报错

The server didn't respond. You may retry your request when the server comes back up.

发现日志

https://xxx:443/bitbucket/rest/branch-utils/latest/projects/~xxx/repos/xxx/branches
java.lang.RuntimeException: 7DELETE
at com.jds.test.httpproxy.miniserver.HttpServerJob$ProxySender.send(HttpServerJob.java:510)
at com.jds.test.httpproxy.miniserver.HttpServerJob$ReqQueue$Customer.run(HttpServerJob.java:204)
at java.base/java.lang.Thread.run(Thread.java:834)

 原来是因为没有处理DELETE代码直接抛异常了

（可以注意到git有超过5次重试，该日志打了5次）

 

2.2 在post中加入delete代码

if ("HEAD".equals(method) || "GET".equals(method)) {
    httpUriRequest = new HttpGet(url);
} else if ("POST".equals(method) || "DELETE".equals(method)) {
    httpUriRequest = new HttpPost(url);

    HttpPost httpPost = (HttpPost) httpUriRequest;
    try {
        httpPost.setEntity(new ByteArrayEntity(originHttp.getBody()));
    } catch (Exception e) {
        e.printStackTrace();
    }
} else {
    throw new RuntimeException(open.intValue() + method);
}

报错：A branch 'startPoint' must be supplied.

然后我想到 delete应该用httpdelete去请求

 

2.3 加入处理delete代码

if ("HEAD".equals(method) || "GET".equals(method) || "DELETE".equals(method)) {
    if("DELETE".equals(method))
        httpUriRequest = new HttpDelete(url);
    if("GET".equals(method))
        httpUriRequest = new HttpGet(url);
    if("HEAD".equals(method))
        httpUriRequest = new HttpHead(url);
} else if ("POST".equals(method)) {
    httpUriRequest = new HttpPost(url);

    HttpPost httpPost = (HttpPost) httpUriRequest;
    try {
        httpPost.setEntity(new ByteArrayEntity(originHttp.getBody()));
    } catch (Exception e) {
        e.printStackTrace();
    }
} else {
    throw new RuntimeException(open.intValue() + method);
}

发现居然还有HttpHead

继续报错：

No content to map to Object due to end of input

这个时候已经猜测 这个delete有body，抓包后果然有，要删的东西放在body了而没有像get那样放在url

 

2.4 改为有body的HttpDelete

https://daweini.wordpress.com/2013/12/20/apache-httpclient-send-entity-body-in-a-http-delete-request/ HTTP DELETE does not forbid a entity body, although it is not a common practice.

private static class MyHttpDelete extends HttpEntityEnclosingRequestBase {
    public static final String METHOD_NAME = "DELETE";

    @Override
    public String getMethod() {
        return METHOD_NAME;
    }

    public MyHttpDelete(final String uri) {
        super();
        setURI(URI.create(uri));
    }
}

if ("HEAD".equals(method) || "GET".equals(method)) {
    if("DELETE".equals(method))
        httpUriRequest = new HttpDelete(url);
    if("GET".equals(method))
        httpUriRequest = new HttpGet(url);
    if("HEAD".equals(method))
        httpUriRequest = new HttpHead(url);
} else if ("POST".equals(method) || "DELETE".equals(method)){
    if("POST".equals(method))
        httpUriRequest = new HttpPost(url);
    if("DELETE".equals(method))
        httpUriRequest = new MyHttpDelete(url);

    HttpPost httpPost = (HttpPost) httpUriRequest;
    try {
        httpPost.setEntity(new ByteArrayEntity(originHttp.getBody()));
    } catch (Exception e) {
        e.printStackTrace();
    }
} else {
    throw new RuntimeException(open.intValue() + method);
}

报错 The server didn't respond. You may retry your request when the server comes back up.

那么把put放上

if ("HEAD".equals(method) || "GET".equals(method)) {
    if("DELETE".equals(method))
        httpUriRequest = new HttpDelete(url);
    if("GET".equals(method))
        httpUriRequest = new HttpGet(url);
    if("HEAD".equals(method))
        httpUriRequest = new HttpHead(url);
} else if ("POST".equals(method) || "DELETE".equals(method) || "PUT".equals(method)){
    if("POST".equals(method))
        httpUriRequest = new HttpPost(url);
    if("DELETE".equals(method))
        httpUriRequest = new MyHttpDelete(url);
    if("PUT".equals(method))
        httpUriRequest = new HttpPut(url);

    HttpEntityEnclosingRequestBase httpPost = (HttpEntityEnclosingRequestBase) httpUriRequest;
    try {
        httpPost.setEntity(new ByteArrayEntity(originHttp.getBody()));
    } catch (Exception e) {
        e.printStackTrace();
    }
} else {
    throw new RuntimeException(open.intValue() + method);
}

成功
