Question

我正在使用Apache HttpClient将我的Android项目从Retrofit迁移到OkHttp。 POST / PUT请求返回错误，即使应用程序自定义标头相同，并且两个请求的Content-Length相等。

GET：工作正常。
POST / PUT：Http Error 400 Bad Request - Invalid Header。即使

供参考，服务器是使用ASP.NET上的Windows Azure实现的。

Apache HttpClient ：

HttpPut put = new HttpPut(<URL>);
StringEntity se = new StringEntity(json);
se.setContentEncoding("UTF-8");
se.setContentType("application/json");
put.setEntity(se);
response = client.execute(put);

改造 + OkHttp ：

// API
@PUT("/<path>")
Response updateThing(@Body Dto dto);

// OkHttpClient
@Override
public Response execute(Request r) throws IOException {
    List<Header> headers = HttpHelper.headerFor(method, url, etc);

    // Create new request with required headers
    Request encodedRequest = new Request(method, url, headers, r.getBody());
    return super.execute(encodedRequest);
}

服务器返回：

---> HTTP PUT https://example.com/path
Content-Type: application/json; charset=UTF-8
Content-Length: 53
{"user_id":"0","latitude":"0.0","longitude":"0.0"}
---> END HTTP (53-byte body)

修改：

使用在线Hurl.it发送POST / PUT请求。
使用Retrofit发送POST / PUT请求时没有任何正文。

不确定服务器期望什么作为标头参数，但您可以在客户端界面上传递任何标头值

@PUT("/<path>")
Response updateThing(@Header("headerName") String headerName, @Body Dto dto);

HTTP 400错误请求 - 在Android上使用Retrofit的无效标头
