httr

问题 I got simple file uploads to Google Drive working using httr. The problem is that every document is uploaded as "untitled", and I have to PATCH the metadata to set the title. The PATCH request occasionally fails. According to the API, I ought to be able to do a multipart upload, allowing me to specify the title as part of the same POST request that uploads the file. res<-POST( "https://www.googleapis.com/upload/drive/v2/files?convert=true", config(token=google_token), body=list(y=upload_file

问题 I'm trying to access the US Census Geocoder batch address API, found here: http://geocoding.geo.census.gov/geocoder/ I've also gone through the documentation for the API here: http://geocoding.geo.census.gov/geocoder/Geocoding_Services_API.pdf I'm trying to use the httr package in R to post a batch csv file of formatted addresses using this format: Unique ID, Street address, City, State, ZIP I've tried the single address request version using getURL from RCurl and that works fine, but

问题 I am in the process of writing a collection of freely-downloadable R scripts for http://asdfree.com/ to help people analyze the complex sample survey data hosted by the UK data service. In addition to providing lots of statistics tutorials for these data sets, I also want to automate the download and importation of this survey data. In order to do that, I need to figure out how to programmatically log into this UK data service website. I have tried lots of different configurations of RCurl

问题 I need to download information from web site that is protected using cookies. I pass this protection manually and then insert cookies to httr . Here is similar topic, but it does not solve my problem: (Copying cookie for httr) library(httr) url<-"http://smida.gov.ua/db/emitent/year/xml/showform/32153/125/templ" cook<-"_SMIDA=9117a9eb136353bd6956651bd59acd37; __utmt=1; __utma=29983421.1729484844.1413489369.1413625619.1413627797.3; __utmb=29983421.7.10.1413627797; __utmc=29983421; __utmz

问题 I am attempting to utilize the Census Bureau's batch geocoder (http://geocoding.geo.census.gov/geocoder/Geocoding_Services_API.pdf) with R. The input addresses are in a data frame, not a CSV. As the addresses are an intermediate step, I do not want to write them to a CSV. I have read several postings on stackoverflow. Hadley's solution (Posting to and Receiving data from API using httr in R) illustrates how to upload an existing CSV file. MrFlick's solution (Uploading a csv to an api in R)

问题 I have a list of URLs and have extracted the content as follows: library(httr) link="http://www.workerspower.net/disposable-workers-the-real-price-of-sweat-shop-labor" get.link=GET(link) get.content=content(x2,as="text") extract.content=str_extract_all(y2,"<p>(.*?)</p>") This gives a "list of 1" with text. The length of each list is dependent on/varies with the URL. I would like to bind the URL [link] with the content [extract.content] and transform it into a dataframe and then import that

问题 I have created a Client ID and Secret Key in Spotify's developer app section. I am referencing this document and want to extend this by choosing multiple artists. https://www.r-bloggers.com/the-eurovision-2016-song-contest-in-an-r-shiny-app/ In this example, they are only choosing 1 artist ID but there are some holes to this, 1) How do you obtain the artist name rather than the artist ID because I can't find a glossary key anywhere for the artist ID? 2) How do you choose multiple artists

问题 I am trying to use RCurl for an oauth 2 authentication. My code is: library(RCurl) myOpts <- curlOptions(httpheader = c(Accept="application/json", "Content-Type"="application/x-www-form-urlencoded")) token <- postForm(authURL, .params = list( client_id ="aaaaaaaaaaaaaaaaaaaaaaaaaaaaa", client_secret = "bbbbbbbbbbbbbbbbbbbbbbbbbbbb", username = "xxxxx@yyyy.zzz", password = pswd), .opts = myOpts, style="POST") The code works just fine on R/Windows, but not on OS X El Capitan. On OS X, I get the

问题 I trying to imitate a CURL request using the HTTR package in R. It's for propbulica's election API. propublica.github.io/campaign-finance-api-docs/ The command line request is documented as follows: curl "https://api.propublica.org/campaign-finance/v1/2016/president/totals.json" -H "X-API-Key: PROPUBLICA_API_KEY" My imitation of this in using R is as follows: require(httr) api_key <- "my key" path <- "https://api.propublica.org/campaign-finance/v1/2016/president/totals.json" data <- GET(path,

问题 Updated: I am trying to access a corporate internal web API using: require(httr) url = 'https://my_server/api/search/query?q=stuff' httr::set_config( config(ssl_verifypeer = 0L) ) data <- httr::GET( url, use_proxy(url = "ipaddress:port"), verbose() ) I get: -> CONNECT my_server:port HTTP/1.1 -> Host: my_server:port -> User-Agent: libcurl/7.47.1 r-curl/0.9.7 httr/1.1.0 -> Proxy-Connection: Keep-Alive -> <- HTTP/1.1 200 Connection established <- Error in curl::curl_fetch_memory(url, handle =
