问题 Here's an example (Express 3) middleware setup thats worked for me globally: app.configure(function () { app.use(express.static(__dirname + "/public")); app.use(express.bodyParser({ keepExtensions: true, limit: 10000000, // set 10MB limit defer: true })); //... more config stuff } For security reasons, I don't want to allow 500GB+ posts on routes other than /upload , so I'm trying to figure out how to specify the limit on specific routes, rather than globally in the middleware. I know the

问题 I've written a python script to take a large file (a matrix ~50k rows X ~500 cols) and use it as a dataset to train a random forest model. My script has two functions, one to load the dataset and the other to train the random forest model using said data. These both work fine, but the file upload takes ~45 seconds and it's a pain to do this every time I want to train a subtly different model (testing many models on the same dataset). Here is the file upload code: def load_train_data(train

问题 I've been looking around for ways to upload large file with additional data, but there doesn't seem to be any solution. To upload file, I've been using this code and it's been working fine with small file: with open("my_file.csv", "rb") as f: files = {"documents": ("my_file.csv", f, "application/octet-stream")} data = {"composite": "NONE"} headers = {"Prefer": "respond-async"} resp = session.post("my/url", headers=headers, data=data, files=files) The problem is that the code loads the whole

问题 I am looking into using WCF for a project which would require the ability for people to upload large files (64MB-1GB) to my server. How would I handle this with WCF, possibly with the ability to resume uploads. In order to handle a larger client base, I wanted to test out JSON via WCF. How would this affect the file upload? Can it be done from JSON, or would they need to switch to REST for the upload portion? 回答1: If you want to upload large files, you'll definitely need to look into WCF
