Set HTTP header in Drive request

阅读更多关于 Set HTTP header in Drive request

问题 I want to detect conflict when updating a file to Drive. To accomplish this, it seems I have to set the If-Match header. Currently, I update the doc to Google Drive with this one-liner: mDriveFile = mService.files().update(mDriveFile.getId(), mDriveFile, byteContent).execute(); What is the simplest way to add the If-Match header in the request? Example in Files: update documentation does not tell how to set HTTP headers. 回答1: You can get the headers from Update object, add your own and put

Using proxies with Google HTTP Client Library for Java

阅读更多关于 Using proxies with Google HTTP Client Library for Java

问题 I use Google HTTP Client Library for Java to make simple JSON requests and parse responses. It works well when I don't go through a proxy. But now I'd like to allow my users to use a proxy (with authentication) functionality in my application. I looked in the HttpTransport, HttpRequestFactory and HttpRequestInitializer classes without any success. I've only slightly modified the examples so far (and mostly it was removing unnecessary code). So where in the code do I add the proxy settings?

In Google HTTP Client library I see only MultipartContent and Part classes that do not seem to be able to handle pure name/value pairs, as StringPart referenced above
