我可以提交故障单和文件附件，但是当我尝试使用图像查看器打开上传的图像时出现此错误
Error interpreting JPEG image file (Not a JPEG file: starts with 0x2d 0x2d)
和我上传时的控制台输出显示
Content-Type: "multipart/form-data;
这是我提交图像的方式，我用HAML表单上传
connection = Faraday.new(:url => "https://account.zendesk.com/api/v2/uploads.json?filename=image.jpg") do |builder|
builder.basic_auth "email/token", "token"
builder.request :multipart
builder.response :logger
builder.adapter Faraday.default_adapter
end
payload = { 'files[]' => Faraday::UploadIO.new(open(params["images"].first).path, 'image/jpg', "image.jpg", "Content-Disposition" => "file") }
response = connection.post do |req|
req.body = payload
req.headers['Accept'] = 'application/json'
end
rtn_data = JSON.load(response.body)
token = rtn_data['upload']['token']
获得令牌后，我按以下方式提交票证：
conn = Faraday.new :url => "https://account.zendesk.com/api/v2/tickets/#{params["ticket_id"]}.json"
conn.basic_auth "email/token", "token"
resp = conn.put do |req|
req.headers['Accept'] = 'application/json'
req.headers['Content-Type'] = 'application/json'
req.body =
'{
"ticket": {
"comment": {
"body": "See screenshot.",
"uploads":["' + token + '"]
}
}
}
end
如果我尝试将文件上传的内容类型更改为
req.headers['Content-Type'] = 'image/jpg'
我收到一个错误
undefined method 'bytesize' for Hash:0x007fb11e104b78
如果我然后将路径更改为.to_json
Faraday::UploadIO.new(open(params["images"].first).path.to_json, 'image/jpg', "image.jpg", "Content-Disposition" => "file") }
我收到另一个错误
没有这样的文件或目录@ rb_sysopen - “/tmp/RackMultipart20171124-15501-1n0qio6.jpg”
但如果我在浏览器中粘贴路线 - 图片会加载 . 知道我做错了什么吗？
