如何从github解析csv? [英] how to parse csv from github?

问题描述

jQuery.ajax({
    url: "https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_time_series/time_series_19-covid-Confirmed.csv",
    type: 'get',
    dataType: 'json',
    success: function(data) {
        console.log(data);
    },
    error: function(jqXHR, textStatus, errorThrow){
        alert("Error: " + jqXHR['responseText']);
    }
});

我需要将输出格式化为json，但这会出错，基本上是试图解析此

解决方案

您必须将dataType用作text，然后使用double for循环运行split，以将数据作为JS对象数组获得:/p>

 jQuery.ajax({
    url: "https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_time_series/time_series_19-covid-Confirmed.csv",
    type: 'get',
    dataType: 'text',
    success: function(data) {
        let lines = data.split('\n');
        let fields = lines[0].split(',');
        
        let output = [];
        
        for(let i = 1; i < lines.length; i++){
           let current = lines[i].split(',');
           let doc = {};
           for(let j = 0; j < fields.length; j++){
               doc[fields[j]] = current[j];
           }
           output.push(doc);
        }       
        
        console.log(output);
    },
    error: function(jqXHR, textStatus, errorThrow){
        console.log(textStatus);
    }
});

jQuery.ajax({

    type: 'get',
    dataType: 'json',
    success: function(data) {
        console.log(data);
    },
    error: function(jqXHR, textStatus, errorThrow){
        alert("Error: " + jqXHR['responseText']);
    }
});

I need the output as formatted json but It's going to error, basically trying to parse this

解决方案

You have to use dataType as text and then run split with double for loop to get the data as an array of JS objects:

jQuery.ajax({
    url: "https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_time_series/time_series_19-covid-Confirmed.csv",
    type: 'get',
    dataType: 'text',
    success: function(data) {
        let lines = data.split('\n');
        let fields = lines[0].split(',');
        
        let output = [];
        
        for(let i = 1; i < lines.length; i++){
           let current = lines[i].split(',');
           let doc = {};
           for(let j = 0; j < fields.length; j++){
               doc[fields[j]] = current[j];
           }
           output.push(doc);
        }       
        
        console.log(output);
    },
    error: function(jqXHR, textStatus, errorThrow){
        console.log(textStatus);
    }
});
