ios - Alamofire 上传仅在 iphone 6s plus 上崩溃
<p><p>我的应用使用 alamofire 4.0.1 在除 iphone 6s plus 之外的所有设备上完美上传照片。(在 iphone 4s、5、5s、6、7、7plus 版本 9.2 和 10.1 上测试)</p>
<pre><code> let image = profileimage
Alamofire.upload( multipartFormData: { multipartFormData in
// import image to request
if let imageData = UIImageJPEGRepresentation(image!, 1) {
multipartFormData.append(imageData, withName: "user_profile.profile_picture", fileName: "profile_picture"+NSUUID().uuidString, mimeType: "image/png")
}
},
usingThreshold: SessionManager.multipartFormDataEncodingMemoryThreshold,
to:baseURL+String(currentUser.id)+"/",
method: .put,
headers: headers,
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, _, _):
upload.responseJSON { response in
let user = createUserFromJSON(response.result.value as! NSDictionary) //crashes here, response is nil
completion(user, nil)
}
case .failure(let encodingError):
let error = encodingError
completion(nil, error)
}
})
</code></pre>
<p>在 iphone 6s plus 上它崩溃了:</p>
<pre><code>2016-12-02 13:26:04.391264 app [] nw_socket_get_input_frames recvmsg(fd 14, 1024 bytes): Connection reset by peer

</code></pre></p>

<p><p>这与 Alamofire 无关!具有最大文件上传大小的是 NGINX。我是通过打印 responseString 而不是 JSON 发现的。它说“请求实体太大”。</p>
<pre><code> upload.responseString { response in
print(response.result.value)
}
</code></pre></p>
