我在python中的请求做错了什么:ValueError:期望值:第1行第1列(字符0)? [英] What am I doing wrong with requests in python: ValueError: Expecting value: line 1 column 1 (char 0)?
问题描述
我什至不知道怎么问这个问题，因为看起来它需要很多代码才能进入细节.除了显示代码外，我还将讨论运行时的行为.
I'm not sure even how to ask the question, as it seems it would require quite a lot of code to get into the details. Rather than show the code, I will discuss the behavior when I run.
我正在使用请求从在线数据库中获取信息.当我运行一个for循环遍历所有条目时，在前20个条目之一(通常是第一个，但并非总是如此)中出现以下错误.列表中的条目都是相同的(只是不同的ID号).我正在使用sleep()来确保我不会超出速率限制(我尝试将睡眠时间增加到荒谬的等待时间，但仍然会收到错误).真正令我惊讶的是，它有些起作用，然后被卡住....什么原因可能导致这种情况?
I am using requests to grab information from an online database. When I run a for loop to go through all of my entries, I get an error like the one below on one of the first 20 entries (usually the first, but not always). The entries in the list are all alike (just different ID numbers). I am using sleep() to ensure that I do not go beyond my rate limit (I have tried increasing sleep to ridiculous wait times, but still get the error). What really surprises me is that it works some, and then gets stuck.... what could cause that?
此外，该代码以前也可以运行，然后我对同一文件中的其他代码进行了大量编辑，但是我不认为自己编辑了与此相关的任何内容.
Also, the code was working before, then I made a large number of edits to other code in the same file, but I didn't think I edited anything related to this.

推荐答案
如果可以发布实际代码，那就太好了.但是，如果由于机密原因而无法这样做，我们可以从堆栈跟踪中推测出一些信息.
It would be nice if you could post the actual code. But if you are unable to do so due to confidential reasons we can surmise some information from the stack trace.
您正在使用一些HTTP协议(SOAP/ResT)API来获取JSON格式的数字(或一系列数字).这些ID编号之一具有意外的字符，或者JSON本身无效.尝试并打印您收到的JSON请求，然后再传递它，以查看哪个失败.然后创建一个单元测试并运行它，以尝试使用断点对其进行分析.
You are using some HTTP protocol (SOAP/ResT) API to get a number( or series of numbers) in JSON format. One of these ID numbers has a character that is not expected or the JSON is invalid itself. Try and print the JSON request you receive before you pass it to see which one fails. Then create a unit test and run it try to analyze it with breakpoints.
可以是基于数据库的某种连字符或外来字符.
Could be some sort of hyphenated or foreign character based on the database.
